cylindrical roller bearings

• 

A cylindrical roller bearing is a type of radial rolling bearing that uses cylindrical rollers as rolling elements, designed for line contact with the raceway.

Key Components

Inner/Outer Ring: Typically features one or two ribs to guide roller movement.

Cylindrical Rollers: High-precision rollers, available in symmetric or logarithmic profiles to reduce edge stress.

Cage: Made of brass, steel, or polymer, ensuring even roller distribution.

Characteristics

High Radial Load Capacity: Approximately 2-3 times that of a ball bearing of the same size.

Moderate Axial Load Capacity: Depends on the rib design.

Suitable for High Speeds: Optimized cage designs allow speeds up to 20,000 rpm.
