Product Info

Crossed Roller Bearings are specialized components designed to support rotational motion in machinery. They feature cylindrical rollers arranged at 90-degree angles in an alternating cross pattern, allowing them to handle radial loads, axial loads, and moment loads simultaneously — all in a single, compact bearing.

This unique design makes crossed roller bearings ideal for high-precision applications, such as industrial robots, machine tools, rotary tables, medical equipment, and camera inspection systems. In addition to being highly durable, these bearings offer smooth and stable rotation, even in demanding environments.

1. Structure and Working Principle of Crossed Roller Bearings
----------------------------------------------------------------------------------------------
Each roller is positioned at a right angle to the next and alternates between the inner and outer raceways. This cross arrangement enables even load distribution and eliminates the need for using two separate bearings, reducing both installation complexity and component size.

Key Benefits:
- Supports loads in all directions (radial, axial, and moment)
- Compact design with high load capacity
- Enhances rotation accuracy and stability
- Perfect for limited-space applications

2. Ideal Applications for Crossed Roller Bearings
----------------------------------------------------------------------------------------------
Crossed roller bearings are commonly used in industries requiring both strength and precision, including:

- Robotic arms in industrial automation
- CNC machines and precision tooling equipment
- Rotary stages in vision systems and automated inspection
- Medical devices, such as MRI machines and diagnostic instruments
- Indexing tables or rotary systems for assembly lines
