Cylindrical roller bearing with inner ring or outer ring without retaining edge, whose inner ring and outer ring can move relatively axially, can be used as free end bearing.
A cylindrical roller bearing with double retaining edges on one side of the inner ring and the outer ring and a single retaining edge on the other side can bear a certain degree of axial load in one direction.
Generally, steel plate stamping cage or solid cage made of copper alloy are used. However, some use polyamide shaped cages.

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.
Lubricant of choice
Lubrication joint type or location
Sealing materials and design options
Dimensions, suitable for housing or insert
Fixing screw options
Paint the shell in any color
Too little or too much lubricant
Incorrect lubricant type
Poor bearing installation
Improper internal clearance
Excessive load and/or speed
Extreme temperature
Pollution
Movement between mounting surfaces
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.
