Product Information

As a core supporting component for ball bearings, the ball bearing housing is designed with the core positioning of "precise adaptation and stable protection". Adopting integral forming technology and precision milling processing, it balances structural strength and easy installation. The inner cavity of the ball bearing housing is precisely polished, with a fit gap of 0.005-0.01mm with the ball bearing, which can perfectly fit the outer ring of the bearing, effectively preventing offset and shaking after installation and ensuring that the transmission accuracy is not affected.

Lead Screw End Bearing

Compared with ordinary bearing housings, the ball bearing housing has achieved dual optimizations in structural design: on the one hand, it strengthens the sealing and heat dissipation performance, with heat dissipation grooves added on the surface to increase the heat dissipation efficiency by 35%, avoiding precision attenuation caused by high temperature generated by high-speed operation of the bearing; on the other hand, it optimizes installation adaptability, supporting various installation methods and realizing direct assembly without complex debugging, which greatly improves installation efficiency. In addition, the ball bearing housing is made of high-strength base material, with excellent wear resistance and corrosion resistance, and its service life is 60% longer than that of ordinary housings, which can stably meet the transmission needs of CNC machine tools and automation equipment.

Lead Screw End Bearing

【Usage Guidelines】When ordering, provide the specifications, installation methods and equipment parameters of the matching ball bearing to ensure that the ball bearing housing is accurately matched with the bearing and equipment, avoiding impact on use due to inconsistent parameters. During installation, violent knocking is prohibited to prevent housing deformation. In daily use, regularly clean impurities on the surface of the housing and check the sealing performance; no complex maintenance is required to maintain its protective and fixing effect, further extending the service life of the ball bearing and the housing.
