Linear guide, also known as line rail, sliding rail, linear guide, linear slide, for linear reciprocating motion occasions, has a higher load rating than linear bearings, at the same time can bear a certain torque, can be in the case of high load to achieve high precision linear motion.

Linear guide features

(1) Auto-centreing capability

DF (45-°45)" combination from the circular groove, when installed, by the elastic deformation of the steel ball and the transfer of the contact point, even if the installation surface more or less letter difference, can be absorbed by the inside of the linear rail slider, the effect of automatic alignment ability and get high precision and stable smooth movement.

(2) with interchangeability

Due to the strict control of manufacturing accuracy, linear guide size can be maintained within a certain level, and the slider has a keeper design to prevent the ball from falling off, so part of the series accuracy with interchangeability, customers can order guide or slider according to needs, but also separate storage guide and slider, in order to reduce storage space.

(3) High rigidity in all directions

The use of four rows of circular grooves, with four rows of steel balls and other 45 degrees of contact angle, so that the steel balls to achieve the ideal two-point contact structure, can withstand the load from the up and down and left and right direction; when necessary can also apply pre-pressure to improve rigidity.

Linear guide can be understood as a rolling guide, is by the steel ball in the slider eye guide between the infinite rolling cycle, so that the load platform along the guide easily linear movement with high precision, and the coefficient of friction down to the usual traditional sliding guide of one fiftieth, can easily achieve a very high positioning accuracy.
