CHTR linear guides rail under the automatic and efficient producing, our high precision suitable for high precision equipment, the the smoothness of the movement is goods which achieves a smooth and noiseless linear motion.
High precision linear guideway is produced by high precision special plane which can polyhedral grind at the same time, detected by laser and other advanced process.
Linear guides are mainly used in machining center, grinding machine ,pressing machine, WEDM machine, transmission machines, etc.

The difference between linear guide slider and linear bearing:
In terms of cost: the same brand, linear guides are more expensive than linear bearings;
From the equipment: linear guides are more accurate than linear bearings, with higher load, stronger stability and longer life;
From the market point of view: linear guides are more suitable than linear bearings, and linear bearings are relatively only suitable for primary processing;
The first patent for a radial style ball bearing was awarded to Jules Suriray, a Parisian bicycle mechanic, on 3 August 1869. The bearings were then fitted to the winning bicycle ridden by James Moore in the world's first bicycle road race, Paris-Rouen, in November 1869.[9]
In 1883, Friedrich Fischer, founder of FAG, developed an approach for milling and grinding balls of equal size and exact roundness by means of a suitable production machine and formed the foundation for creation of an independent bearing industry.
