THK SVR45LRH Linear Guide SVR45 SVR45LR SVR45LRH Rail Slider

Structure and Features

THK SVR45LRH Linear Guide is a product with high rigidity and high load capacity in the ball retainer type LM rolling guide series. Considering the use environment of equipment such as machine tools, a variety of accessories are provided to enhance its dustproof performance, thereby achieving the performance maintenance and high reliability of the LM rolling guide. THK SVR45LRH Linear Guide has extremely high rigidity and is easily affected by the misalignment of the center line of the mounting surface or installation errors in structure.

[Super heavy load and improved damping effect]

THK SVR45LRH Linear Guide adopts an arc-shaped deep groove with a rolling surface curvature close to the diameter of the steel ball. As the load increases, the contact area of ​​the steel ball also increases, which can obtain high load capacity and further improve its damping effect (damping).

[Improved dustproof performance]

The newly developed protector improves the ability to remove foreign matter and enhances dustproof performance. In addition, the THK SVR45LRH Linear Guide adopts a side scraper to reduce the intrusion of foreign matter into the LM slider, and the performance of the W rolling guide can be maintained for a long time even in harsh environments.
