Introduction

Ultra-thin XRB series crossed roller bearings are a type of high-precision rotary bearing that are specifically designed for use in compact machinery where space is limited. They are characterized by their ultra-thin design and high rigidity, which makes them ideal for use in high-precision applications such as robots, precision machinery, and other applications where precise rotary motion is required.

The ultra-thin design of XRB series crossed roller bearings allows for a high degree of accuracy and rigidity in rotary motion, even in applications where space is limited. The rollers in these bearings are arranged in a 90-degree crossing pattern, which provides high rigidity and load capacity in both the radial and axial directions.

Ultra-thin XRB series crossed roller bearings features

High speed capacity

XRB series bearings are capable of operating at high speeds, which makes them ideal for use in high-speed machinery.

Low noise and vibration

XRB series bearings are designed to have low noise and vibration levels, which helps to reduce noise and wear in high-precision machinery.

High reliability

XRB series bearings are designed for high reliability and long life, which helps to reduce maintenance costs and improve the overall efficiency of machinery.
