High straightness of guideway with precision machining technology. The the smoothness of the movement is goods which achieves a smooth and noiseless linear motion.
Small friction in motion, greatly reducing the power loss of the station, Suitable for high-speed, frequent start-up and commutation of moving parts.
Linear guides are mainly used in mechanical structures with Machining Center, grinding machines, Line Adapter, packaging machines, etc.

Data unit is mm
(1) thk is interchangeable
Due to the strict control of production precision, the size of the linear guide can be maintained within a certain level, and the slider has a retainer design to prevent the steel ball from falling off. Therefore, some series of precisions are interchangeable, and customers can order the guide rails or The slider can also store the rails and sliders separately to reduce storage space.
(2) High rigidity in all directions
The four-row circular groove is matched with the contact angle of 45 degrees such as four rows of steel balls to make the steel ball reach the ideal two-point contact structure, and can withstand the load from the up and down and left and right directions; if necessary, it can apply preload to improve rigidity.
(3) Self-aligning ability
The DF (45-°45)° combination from the circular groove can be absorbed by the linear slider even if the mounting surface is slightly deviated during the installation by the elastic deformation of the steel ball and the transfer of the contact point. The effect of automatic self-aligning ability results in smooth motion with high precision and stability.
Designed in 1968 and later patented in 1972, Bishop-Wisecarver's co-founder Bud Wisecarver created vee groove bearing guide wheels, a type of linear motion bearing consisting of both an external and internal 90-degree vee angle.

In the early 1980s, Pacific Bearing's founder, Robert Schroeder, invented the first bi-material plain bearing which was size interchangeable with linear ball bearings. This bearing had a metal shell (aluminum, steel or stainless steel) and a layer of Teflon-based material connected by a thin adhesive layer.[14]
Today ball and roller bearings are used in many applications which include a rotating component. Examples include ultra high speed bearings in dental drills, aerospace bearings in the Mars Rover, gearbox and wheel bearings on automobiles, flexure bearings in optical alignment systems, bicycle wheel hubs, and air bearings used in Coordinate-measuring machines.
