What are the types of crossed cylindrical roller bearings?

Crossed cylindrical roller bearings, also known as crossed roller bearings, are a type of rolling element bearing designed to handle both radial and axial loads simultaneously. These bearings have cylindrical rollers arranged perpendicular to each other in a V-shaped groove, forming an X-shaped configuration. This design provides high rigidity and load-carrying capacity in a compact structure. There are several types of crossed cylindrical roller bearings, each with specific features and applications.

Crossed cylindrical roller bearing types

Single Row Crossed Roller Bearings

This is the most basic type, consisting of a single row of cylindrical rollers with alternating orientations.

Suitable for applications with limited radial space and where high axial rigidity is required.

Commonly used in robot joints, industrial robots, and precision machinery.

Double Row Crossed Roller Bearings

In this type, two rows of cylindrical rollers are arranged in a crossed pattern.

Offers higher load-carrying capacity and increased rigidity compared to single row crossed roller bearings.

Used in applications where higher radial and axial loads need to be accommodated, such as machine tools and industrial robots.

Three Row Crossed Roller Bearings

Features three rows of cylindrical rollers arranged in a crossed pattern.

Provides even higher load capacity and stiffness compared to the double row design.

Commonly used in heavy-duty applications like construction machinery, industrial robots, and turntables.

Separable Crossed Roller Bearings

This design allows the inner and outer rings to be separated, simplifying installation and maintenance.

Beneficial for applications where ease of assembly and disassembly is crucial.
