Product introduction

Cylindrical roller bearings are available in various designs, such as with different types of cages, inner and outer ring configurations, and clearance levels


The cylindrical rollers are also made of steel and are arranged parallel to the axis of rotation. The cage, usually made of brass or steel, holds the rollers evenly spaced apart and prevents them from coming into contact with each other.


Cylindrical roller bearings are commonly used in various machinery and equipment, including automotive applications, industrial machinery, and power transmission systems.

They are known for their high load-carrying capacity, relatively high stiffness, and ability to accommodate axial loads in addition to radial loads.
