Cleaner SteelIf there was ever an opportunity to cut corners, this would be it; use a steel of marginal quality, sell at a reduced price and hope no 1 notices the difference.
An innovator in bearing steel, SaiFan uses SUJ-2 steel for balls and rings. SUJ-2 steel is ultra-clean, vacuum-melted bearing steel, much cleaner than typical industry standard steel. With an oxygen content lower than 9 parts per million coupled with the proper treatment, saifan bearings have nearly double the fatigue life.

Superfinished Raceways and Maximum Sphericity

A super finish on both raceways means less wear at start-up, better performance out of the lubricant and smooth, quiet operation. saifan accomplishes this through a proprietary method of honing the raceways to finishes at the sub-micron level. For added value, saifan tests every bearing for low noise and vibration characteristics before the “quiet” rating is applied.

Rough bearing raceways inhibit lubrication and can lead to increased noise. At SAIFAN, raceways for electric motor bearings are finished to a super-smooth condition using a custom honing process they developed specially for this purpose. This finish guarantees excellent lubrication and extends bearing life. To enjure the smoothest possible operation, SAIFAN uses high-grade steel balls manufactured using a proprietary process. The result is an extremely quiet running bearing.

The ball set plays an integral role in the smooth and efficient operation of a bearing. Not only do they need to be extremely close in size and tolerance, but are required to be nearly perfect in shape. At least by SAIFAN standards.

Cage Advancements

It’s the small things that sometimes make the difference. Like the close tolerances SAIFAN achieves by coining the cage pockets. The results are better distribution of the lubricant, less noise and reduced internal friction. The benefit is a strong cage with a lower operating temperature and higher speed limits and ultimately it means longer bearing life.

SAIFAN also provides molded polyamide cages with optimized ball pocket designs. Their conformance with the rolling elements reduces friction for quieter operation with improved grease life. Bearings with polyamide cages also have lower torque at high speeds and are more tolerant of misalignment.

High-Temperature Grease
SAIFAN offers a variety of lubricants to suit a wide range of applications. When it comes to electric motors, the AS2 and NS7 greases are superior quality grade lubricants formulated to deliver low starting torque and extended service life.

This grease offers high-temperature capability with low-noise characteristics in its electric motor bearings. The wide temperature range prolongs the life of the grease, which in turn extends the bearing life. You get smoother and quieter operation throughout the life of the bearing.

Quality from Start to Finish
In the manufacturing process, SAIFAN uses the latest in automated equipment to achieve superior consistency. At each step in the process, the latest Statistical Process Control (SPC) techniques are applied. SAIFAN builds in quality you can count on, with thorough in process gauging. Each bearing is tested for noise and vibration levels, using side-by-side Anderometer in the manufacturing line. The Anderometers measure the degree of geometric and surface protection. Any bearing that does not pass the low, medium and high-frequency tests is automatically rejected.

The Right Clearance
To accomplish that goal SAIFAN identified the optimum RIC for bearings: CM. SAIFAN believes this range provides the right amount of clearance to meet the goal while controlling the air gap between rotor and stator, delivering quiet operation and increased efficiency.

Shields, Seals and the VV
Bearings with 2 enclosures are pre-greased at the factory and are classified as “greased for life”. This simply means that the type and amount of grease is sufficient to outlast most general applications, with the exception of temperature extremes, contamination, high load and high speed.

Enclosures are defined as either contact or non-contact and refer to any gap at the inner ring. The popular Z metallic shield does a good job of keeping the grease in place and larger contaminants out of the bearings. SAIFAN applies an anti-corrosive coating to their Z shield in the event of moisture and because they are non-contact, their operating speed and starting torque are unaffected.

For more arduous service conditions, the seal is in full contact with the inner ring, increasing grease retention and excluding a wider range of contaminants from entering the bearing but generate more head and therefore have reduced operating speeds. Enter the V seal from SAIFAN. Zero drag, low staring torque, maximum operating speeds, no excessive heat and increased grease retention and contaminant protection over the shield design. The V seal from SAIFAN delivers an alternative that’s fast becoming the standard in all bearings.

Types of Ball Bearings

If you’re looking to purchase a new ball bearing, there are many different types available. Learn about Single-row designs, Ceramic hybrid bearings, and Self-aligning ball bearings. You can also choose from stainless steel or single-row designs. Then, read about the different types of materials available to you. You’ll have an easier time making a decision. After all, you won’t have to worry about maintaining your new ball bearing, since it will be maintained by your supplier.

Single-row designs

Ball bearings with a single-row design have a high load-carrying capacity. They are used in applications where high loads must be handled smoothly. A single-row design is a good choice when the material’s properties require high load-carrying capacity but limited axial load capability. Single-row designs use two bearings with similar design features, but they have different mounting methods. Single-row designs can be adjusted either against one another to accommodate axial loads.
The single-row design is suitable for high-speed applications, but also has some disadvantages. The contact angle a is the angle between the radial plane and contact line. The larger the angle, the higher the axial load carrying capacity of the bearing. Single-row angular contact ball bearings are suitable for higher axial forces. Single-row angular contact ball bearings have a single-row design and support high axial forces in one direction. Single-row ball bearings are available in both pressed steel and machined steel cages.
Angular contact ball bearings with a single row feature a cage made of fiber-glass reinforced polyamide 66. These are available in diameters up to 130 mm. Four-point angular contact ball bearings use brass, steel, or brass plate. They have good running properties and a low coefficient of linear expansion. Single-row designs are easy to mount and are widely available. Alternatively, they can be mounted with a universal match design, which allows them to be easily adjusted.
One-row angular contact ball bearings are generally not suitable for angular misalignments because they are unsuitable for compensation of angular misalignments. Misalignments cause internal forces in the bearing which reduce its radial load capacity and life expectancy. This type of bearing is not suitable for adjacent mounting as it increases the chances of misalignment. However, it is a suitable choice for applications where only one bearing is required per bearing position.

Ceramic hybrid bearings

While all-ceramic bearings are limited to very specialized applications, Si3N4-based hybrid bearings are finding use in a wide range of high-speed machines. Compared to steel, ceramics are less susceptible to centrifugal forces, which are directly proportional to the mass of the balls. Because Si3N4 replacement balls have a lower density than steel, these bearings reduce the stress placed on the outer race.
The benefits of hybrid bearings are clear: they allow for higher speeds and loads than full-ceramic bearings, and they require no lubrication. Because of their many benefits, many industrial equipment operators are switching to these innovative bearings. CBR is one company that specializes in ceramic hybrid bearings and can help you find the best product for your application. If you are thinking about purchasing ceramic bearings for your next machine, here are some things you need to know about them.
A ceramic ball bearing surface has an extremely low coefficient of friction, which is important for applications that require low friction and high speeds. Ceramic balls also have a higher hardness than steel balls, which increases their life. In addition to this, ceramic hybrid bearings have superior thermal properties, generating less heat even when spinning at high speeds. These properties make ceramic hybrid bearings an ideal choice for high-speed machinery, especially electric motors. They are also suitable for applications that operate under water.
A ceramic ball hybrid bearing is much less susceptible to temperature fluctuations and wear. Because they are essentially indestructible, ceramic balls do not generate wear particles from the adhesive wear. They can run at significantly higher speeds than steel balls. Ceramic balls are also more resistant to moisture. For this reason, grease is a recommended lubricant in most ceramic bearing applications. These lubricants offer superior protection against moisture and corrosion. Further, they are available in many types.

Self-aligning ball bearings

A self-aligning ball bearing is one type of self-aligning bearing. These bearings are recommended for use in flex shaft systems. Their self-aligning feature prevents them from misaligning when in use. They can be used in both single and multiple-joint systems. In addition to self-aligning ball bearings, these units also feature flex shafts.
These self-aligning ball bearings come in a variety of configurations, including cylindrical, round, tapered, and straight bore. Their inner ring is tapered to meet specific tolerances. They are suitable for operating temperatures ranging from -30°F to 120°F. Their wide range of applications allows them to be used in general machinery, precision instruments, and low noise motors. In addition, they are available in a variety of outside diameters, widths, and internal clearances.
Self-aligning ball bearings have two rows of balls and one common sphered raceway in the outer ring. This enables them to automatically compensate for angular misalignment, which may be caused by machining and assembly errors or deflections. Compared to spherical roller bearings, these self-aligning ball bearings generate less friction. They run cooler even at high speeds. Self-aligning ball bearings also offer free engineering support.
Self-aligning ball bearings are designed for difficult shaft alignment. They are double-row, self-retaining units, with cylindrical or tapered bores. These bearings are available in open and sealed designs, and can also be used in applications with misalignment. They are also available with an outer ring that rotates in relation to the inner ring. When it comes to shaft misalignment, self-aligning ball bearings are a great solution.

Stainless steel

Stainless steel is a metal that resists corrosion and is highly durable. Its corrosion-resistant and water-resistance properties make it a good choice for bearings in food and marine applications. Additionally, stainless steel has hygienic benefits. Here are some of the benefits of stainless steel ball bearings. Read on to learn more about these amazing bearings! We’ve included some of the most common uses for stainless steel.
Hardness is important in a ball bearing. Steel uses the Rockwell C scale to measure hardness. A grade 25 steel ball bearing is accurate to 25 millionths of an inch, while a grade five ceramic bearing is less than a half-inch round. Although roundness is important, it shouldn’t be overemphasized, as the bearing surfaces may not be as accurate as the grade of the metal. And remember, a higher price tag doesn’t mean a better product.
Stainless steel ball bearings are available in a variety of alloys. The alloys used in manufacturing a stainless steel ball bearing vary in hardness, strength, and ductility. Stainless steel ball bearings have high corrosion-resistance properties. Additionally, they have long lubrication lives. These benefits make them a popular choice for industrial applications. These bearings are easy to maintain, reduce replacement costs, and offer corrosion resistance.
The NTN Sentinel Series is a premium line of stainless steel bearings. The solid lube is NSF H1 registered and prevents grease from leaching into food. It is also corrosion-resistant and doesn’t need to be coated. The seals and slinger create a water-resistant barrier between the steel ball and the lubricant. It also adds safety and security to the bearing.

Plastic balls

For applications where noise and weight are major concerns, plastic balls are ideal. These non-magnetic balls are ideal for MRI X-ray machines and sensors. They are also easy to lubricate, and are non-magnetic. A polymer ball bearing is the lightest of all three types. This makes them a good choice for many industries. Read on to learn more. This article will introduce some of the advantages of plastic balls for ball bearings.
Although ceramic ball bearings are more durable and offer many advantages, they are more expensive than plastic. Fortunately, plastic ball bearings offer a cheaper alternative. These bearings feature all-plastic races and cages. Depending on the application, plastic balls can be used in applications involving chemicals. In these cases, plastic ball bearings are available with a C160 grade, which is safe for use in temperatures below 176 deg F.
Medical devices often require precision specialty balls, which are made of glass, stainless steel, and plastic. These bearings must meet stringent cleanliness requirements. To meet the most stringent requirements, they must undergo ultrasonic cleaning. These bearings are available in plastic raceways, and are also available with glass or stainless steel balls. Polyethylene balls are lightweight and can be used in a variety of applications. They can be ordered in different sizes and tolerances to meet specific requirements.
Plastic balls for ball bearings are often mounted into other parts, such as plastic wheels, pulleys, and housings. They can be seamlessly integrated into other parts of a machine, which reduces assembly time and improves affordability. One important advantage of plastic bearings is that they are rust-resistant. As such, they can be used in harsh environments without causing any damage. If a piece of equipment is exposed to extreme temperatures, polymers are the ideal choice.
