What is a Cross roller?

A cross roller is a type of bearing commonly used in precision machinery and devices, featuring rollers arranged in a cross pattern. Unlike traditional bearings, the rollers in a cross roller are positioned at right angles to each other. This unique design provides high precision and load-bearing capacity, enabling it to handle both axial and radial loads simultaneously.

Key features of cross rollers include:

・High Precision: The crossed arrangement of rollers ensures very small gaps, maintaining high accuracy.
・Load-bearing Capacity: The crossed rollers evenly distribute loads from different directions, making them ideal for heavy load applications.
・Compact Design: Cross roller bearings are often used in compact devices, as they require less space while providing reliable performance.
Cross roller bearings are widely used in applications where precise rotational movement is necessary, such as in robot joints, precision equipment, and optical instruments.

Application of Cross roller

１．Robot Arms: Cross rollers are used in robot joints to enable precise rotational movement and ensure smooth operation of the joints.
２．Precision Machinery: In machinery that requires high accuracy (such as CNC machines or manufacturing equipment), cross roller bearings evenly distribute axial and radial loads, ensuring stable operation.
３．Optical Instruments: Used in the rotating components of optical devices like cameras or microscopes, where high precision is required for fine movements.
