Spherical Roller Bearing
In SKF Spherical Roller Bearing, the raceway of outer ring is designed to have a spherical profile, whose centre coincides with the bearing’s centre point.
This type of bearing is self-aligning type, hence can be used for applications where a misalignment of shaft may arise either due to an erroneous mounting or due to shaft deflections. The outer ring generally has lubrication holes and grooves. These bearings are suitable for very high radial impact load applications, and a moderately high level of bi-directional axial load.

- Like skf spherical roller bearing with adapter sleeve(22220 bearing sleeve,22222 ek bearing sleeve,22212 bearing sleeve)is spherical roller bearing with adapter sleeve.
- The self-aligning design of spherical roller bearings supports high radial loads and heavy axial loads in both directions.
- Each bearing consists of an inner ring with two raceways and an outer ring.
- Spherical roller bearings withstand the most demanding conditions by resisting galling and wear despite constant vibration, misalignment and shock loads.
- They maintain dimensional stability and can withstand high radial loads and moderate axial loads.
- Their performance enhancements include extremely tight radial play tolerances, additional accuracy in ID and OD, and super-finished, heat-treated rollers with excellent shock load capability.
- Spherical roller bearings are best suited for applications that require vibration resistant components, but that is not the only quality of these bearings.
- These bearings can withstand heavy loads because of their ring alignment.
- Because of the curved outer ring, spherical bearings are self-aligning and can absorb shock, allowing the equipment to withstand high axial and radial loads even in harsh environments with high vibration.
- Even in this harsh operating environment, roller bearings often have high accuracy. Typically these bearings are available in two different types, which have completely different designs, constructions, specifications and applications.
- Single row spherical roller bearings. Because of their design, they are also known as cartridge bearings and they are widely used where only low radial load carrying capacity is required.
- Except for the load capacity differences, single row these bearings are very similar to their counterparts in terms of performance and durability.
- Double-row spherical roller bearings
- They are used where high radial load carrying capacity is required, which makes them an important part of almost all heavy machinery. The design differences between the two are obvious;
- double row roller bearings are equipped with a central flange to optimize the overall performance of the machine.
Application of Spherical Roller Bearings
- Depending on the field of activity and application, needle roller and cage assemblies can be integrated between the rings to strengthen the assembly and ensure the connection between the various mechanical parts.
- Therefore, needle roller bearings come in many forms (cages, bushes, bearings with solid rings, combination bearings, split spherical roller bearing to meet all technical constraints of the industrial market.
- The smallest cross-section in a split spherical roller bearing cage assemblies provide a very compact solution for applications where space is limited.
High load capacity
- Due to the large number of rollers, the needle roller and cage assembly has a high load-carrying capacity.
high stiffness - The split spherical roller bearing and cage assembly has high stiffness due to the large number of small diameter rollers.

FAQ
Due to their internal design, ball bearings cannot usually be disassembled down to the component level; therefore, they cannot usually be refurbished.
Solid base shells are manufactured without cavities and fillers; they are stronger than hollow bases, and there are no traps for bacteria and fungi to grow. In the thermoplastic shell, the sturdy base will not break under steam or high-pressure washing. The hollow base saves material and weight to reduce costs. Some people use epoxy resin to backfill the hollow base to eliminate the trap of bacteria breeding, but this will not increase the strength, will cause the installation surface to be uneven, and water will seep between the shell and the filling material, causing cracking.
Use particularly thermally stable bearing rings, larger internal clearance (C4), specially selected lubricants that will not decompose at high temperatures, and zinc anodized flinger. There are two basic versions of our high temperature bearings. The suffix “C4HR5” represents the bearing that can withstand 400°F, and the suffix “C4HR23” represents the bearing that can withstand 450°F.
For critical applications such as pulp and paper processing, printing and packaging, material tearing can cause expensive downtime due to excessive torque and vibration.
The two biggest factors affecting the starting and running torque of the bearing are the seal design and lubricant selection. The shaft and bearing seat fit, component accuracy and surface finish, and retainer design also have some influence.
In higher speed applications, non-contact sealing devices are usually required to minimize operating torque and heat generation, so oil baffle rings and secondary sealing devices are usually required. Flowing oil lubrication systems are usually the best solution.
After proper installation, most seated bearings only need to be relubricated regularly with a small amount of grease and checked to ensure that they operate at low temperatures, quietness, and sufficient accuracy.
This depends on many factors, such as the application’s load conditions, operating speed, duty cycle, temperature, and operating environment. The technical information section of this website provides some basic information. Our engineers can help you determine more specific theoretical life calculations.
When noise and/or operating temperature increase or operating accuracy decreases, bearings should be replaced.

The noise emitted by the bearing may be caused by a combination of one or more factors, such as insufficient working clearance, excessive working clearance, changes in working clearance due to temperature, damage to the contact area, contamination, inappropriate lubricants or The raceway is damaged.
Lubricants have five basic functions for bearings:
Reduce friction
Reduce wear
Reduce temperature rise
Minimize corrosion
Seal contaminants
We do not recommend mixing grease. Mixing incompatible greases will cause the mixture to harden, preventing it from releasing any oil. Mixing incompatible greases can also soften the mixture, which releases all the oil. In either case, the mixture will not be able to properly lubricate the bearing. We strongly recommend using the same type of grease originally provided with the bearing.
