To be the top bearing manufacturers in world is our goal,ZYSL bearing Co., Ltd is the first choice of your bearing manufacturers list!
ZYSL Linear Guide Rail are mainly used in automated machinery, such as machine tools, bending machines, laser welding machines, etc. Of course, linear guides and linear axes are used together. The linear guides are mainly used in mechanical structures with relatively high precision requirements. Instead of intermediate media between the moving elements and fixed elements of linear guides, rolling steel balls are used. Because the rolling ball adapts to high-speed motion, small friction coefficient and high sensitivity, it can meet the working requirements of moving parts, such as the tool holder and pallets. If the force acting on the steel ball is too large, the steel ball is subject to a preloading time that is too long, resulting in an increase in the carriage movement resistance.

Specification of linear motion bearing sf30:
The surface of Linear shaft was specially ground,hard-chromium plated and mirror polished. It has good wear resistance and corrosion resistance. With the surface of the chrome plated rod to choose after high-frequency processing. It is applicable to ordinary standard and special specifications can be customized, with a good quality guarantee. Linear shaft is ground and polished within a consistent surface finish range resulting in a higher level of predictable performance. This surface finish results in more evenly distributed loading, decreased the amount of wear and particulate generation, and reduced drag. Finally, the consistent dimensional tolerances along the entire length of the inch steel shafting maximize consistent bearing operation.
