Roller Linear Guide

Made of bearing steel, GZB roller linear guide is composed of rail, slide block, rollers, reverse unit, retainer, roller cage, and seal gasket, etc. The roller linear guide has high rigidity rollers and its load bearing pattern is changed from the traditional point contact to line contact. The roller linear guide can withstand a large torque due to its inner V type groove design. In addition, the structure of slide block is optimized by finite element analysis. All of this contributes to the high load carrying capacity of our roller linear guide. Moreover, the contact angle between the roller and raceway is 45º, enabling the roller linear guide to have equal load in four directions.

Roller cage is set among rollers to keep them apart and avoid collision, eliminating any noise caused by roller collision. It also makes the rollers move straight and stably. There is an oil layer between roller and the cage which greatly reduces friction and reduces heat generated by the linear guide during moving, ensuring high speed and high accuracy motion. What's more, with lubricating grease stored in the cage, the roller linear guide is free from maintenance for a long period of time and the operating life is extended. These are a few reasons why our roller linear guide is widely used for machining centers, NC lathes, grinders, etc.
