Bearing Rail JSH25 Series Guideway Precision Machine Linear Guide

Interchangeability

For the tightly control of production precision, all the size can be maintained at as table tolerance range. So the interchange type linear guide can keep the same smoothness, preloading and precision when  block arbitrarily assemble on the same type of rail. It is very easy to assemble and repair.

High Positioning Accuracy

When machine that vectoring by linear guide, the friction coefficient will be 1/50 of sliding frictionco efficient, as the friction method of linear guide is rolling friction, the disparity of dynamic friction and static friction will become smaller, when machine runs, there will be no slipping phenomenon and the positioning accuracy can reach very high

Four Direction Equal Load Capacity

JSH rail rolling body is to be designed with special pressure angle which make it can bear the same rated load of its radial, anti radial and horizontal direction

High Rigidity. High Load

JSH Linear guideway is designed with four columns arc grooves which increase the contact area, compare with two cloumns groove design has been greatly improve on the loading capacity ,contact stiffness and system rigidity.

JSH linear guideway is produced by high precision special plane which can polyhedrally grind at the same time, detected by laser and other advanced process . all of these guarantee the manufacturing precision of TRH linear guideway

Smoothness, Low Noise

The returning device of JSH linear guide adopt a simple and lubricant ball recirculation design with shocker sistant circulative accessory -strengthening synthetic resin, the smoothness of the movement is good which achieves a smooth and noiseless linear motion.

With automatic self-aligning capability

Arc groove design of the front combination makes the linear guideway has the ability to automatically adjust the center, even if to give preloading it can absorb installation error, and maintains a high precision, smooth and stable linear motion.
