Cylinder roller bearing
Most of cylindrical roller bearings are separable. This make it very convenient to mount and dismount. Cylindrical roller bearings can carry heavier radial load, and are suitable to be used in the condition of high speed. This type of bearings can allow a small angular error between inner axes and outer axes in the range of 2′ ～ 4′. Therefore, it requires higher machining precision on shaft and housing; otherwise, asymmetrical load and stress would be focused at the position of raceway. However, this situation can be improved by correcting the contacted generatrix of rollers or raceways. According to different rows, cylindrical roller bearings are divided into single row, double-row, and multi-row cylindrical rollers. These differences are also displayed on the design of flange position.

Product Description of Cylinder roller bearing
High-quality brand, high-quality materials
Whether you are looking for carburized inch series cylindrical roller bearings made in the United States, or metric series, fully hardened bearings, they can meet your application needs.
To provide cylindrical roller bearings, we use high-quality steel and special heat treatment to extend the service life and increase reliability when the application requires it.
The precise control of heat treatment, size and surface finish of the components further contributes to the realization of reliable bearing performance.
As heat treatment
Austenite strengthening process (AS) is a special heat treatment applied to rolling elements. By chemically changing the surface chemistry of the roller, a thin layer of retained austenite can be produced, which can generate compressive stress and extend the life of the bearing. AS treatment results in a material life multiplier of 1.5.
HL surface treatment
High lubrication (HL) surface treatment is a unique micro-pitting surface treatment that can extend bearing life in applications with insufficient lubrication. Based on the theory that the oil film formation in the bearing contact area can be improved by changing the characteristics and direction of the surface finish of the parts, the unique micro tank can effectively capture the oil and transport it to the place where it is needed.
Large capacity separator
The developed technology combines the high load capacity of the full complement bearing with the high speed capacity of the cage design.
By placing resin rolling element separators between the rollers, it is possible to maintain the same number of rollers as the full complement design and prevent the rollers from contacting to reduce friction and heat generation.
By optimizing the shape and guiding method of the separator, the same allowable speed can be achieved as the bearing with a cage.
Application of Cylinder roller bearing
Cylindrical roller bearings may have the simplest structure in the roller bearing category. These bearings are suitable for carrying relatively high loads in high-speed applications.
There is linear contact between the rolling elements and the raceway.
Compared with ball bearings, the relatively large contact surface area enables cylindrical roller bearings to withstand greater loads. However, their axial load carrying capacity is limited. Many variants of this bearing type can be used to meet specific application requirements.
These bearings are suitable for applications involving light axial loads, especially where precise shaft alignment is difficult. Cylindrical roller bearings have two types of bores, namely cylindrical and tapered. Their cages are made of pressed steel or brass.
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.
These bearings use cylindrical rollers as rolling elements and have a high load carrying capacity.
The rollers are guided by the ribs of the inner ring or the outer ring.
The inner ring and the outer ring can be separated for ease of assembly, because the inner ring and the outer ring are usually press-fitted to the shaft and the bearing seat, respectively.
The bearing ring can move freely in the axial direction on a bearing without inner or outer ring ribs, which makes cylindrical roller bearings very suitable for applications where the shaft is thermally expanded, such as electric motors.

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 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.
