Cylindrical Roller Bearing
Cylindrical roller bearings use cylindrical rollers as rolling elements, which have high load capacity. The roller is guided by the rib of the inner or outer ring. The inner ring and the outer ring can be separated to facilitate assembly, because the inner ring and the outer ring are usually pressed on the shaft and bearing seat respectively. On bearings without inner or outer ring ribs, the ring can move freely in the axial direction, which makes cylindrical roller bearings an ideal choice for applications that experience thermal expansion of the shaft, such as electric motors

Cylindrical Roller Bearing Types
As one of the largest cylindrical roller bearings suppliers in China, we can produce major brands and various types of cylindrical bearing rollers, such as: timken split cylindrical roller bearing and link belt cylindrical roller bearings and the following most common types of roller bearings
Features and benefits of Cylinder roller bearing
- High load carrying capacity
- High stiffness
- Accommodate axial displacement
Except for bearings with flanges on both the inner and outer rings.
- Low friction
The open flange design
- Together with the roller end design and surface finish, promote lubricant film formation resulting in lower friction and higher axial load carrying capability.
- Long service life
The logarithmic roller profile reduces edge stresses at the roller/raceway contact and sensitivity to misalignment and shaft deflection.
- Enhanced operational reliability
The surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.
- Separable and interchangeable
The separable components of our cylindrical roller bearings are interchangeable. This facilitates mounting and dismounting, as well as maintenance inspections.
Main applications of cylindrical roller bearings
Large and medium-sized motors, locomotives, machine tool spindles, internal combustion engines, generators, gas turbines, reducers, rolling mills, vibrating screens and lifting and transporting machinery, etc.

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
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 temperature rise
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.
