RAU Crossed Roller Bearings

What is RAU Crossed Roller Bearings?

RAU Crossed Roller Bearings are a type of high-precision bearing designed to provide exceptional rigidity and load-carrying capacity. Unlike traditional roller bearings, crossed roller bearings feature cylindrical rollers that are arranged in a crisscross pattern. This unique arrangement allows the bearing to handle radial, axial, and moment loads simultaneously, making it ideal for applications requiring precise motion and high reliability.

These bearings are engineered to withstand extreme conditions, including high speeds, heavy loads, and harsh environments. This makes them a preferred choice in various industries, including aerospace, robotics, machine tools, medical equipment, and automotive manufacturing.
