THK SHS15

Caged Ball LM Guide (Linear Motion Guide)

Use of a ball cage eliminates friction between balls, and achieves low noise, acceptable running sound, long-term maintenance-free operation, and superbly highspeed response.

1.Product Introduction of this model

Global Standard size Model SHS

(SHS15/SHS20/SHS25/SHS30/SHS35/SHS45/SHS55/SHS65)

Since each row of balls is arranged at a contact angle of 45°, the model THK SHS15 can be used in all directions.

 

2.Product Feature And Application

Ball - holding linear guide - track world standard structure and specialty

The steel ball rolls along four rolling surfaces of THK SHS15 guide rail and slide block after precise grinding. The steel ball is moved in a circular motion through the ball retainer and the end cover plate assembled on the LM slide.

3.Product Feature And Application

For THK SHS15, slider on the four direction (radial, the radial and lateral) have the same rated load, the steel column is designed according to the contact Angle 45 ° configuration, so no matter what kind of posture can be used. In addition, it can maintain a low friction coefficient on one side and strengthen the rigidity in four directions by applying an equal pressure. At the same time, the SHS slider is designed with high rigidity due to the low cross-section height, so that stable and high-precision linear motion can be obtained.

4.Production Details

Because the radial clearance of the THK SHS15 linear guide can greatly affect the walking accuracy, load bearing capacity and rigidity of the linear guide, it is very important to select the appropriate clearance according to the usage. In general, the selection of a negative clearance (i.e., the application of preloading) can have a good effect on service life and accuracy, given the vibrations and shocks that may be generated by the reciprocating motion
