THK HRW12

THK HRW12

The steel ball rolls along the four rolling surfaces of HRW guide rail and slide block after precision grinding. By assembling the end cover plate on the slider, the steel ball column moves in a circular manner

1?Product Introduction of the THK HRW12

The HRW slider USES a holding plate to hold the ball, so the ball will not fall off even if the slider is pulled out of the guide. (except HRW12 and 14 lr type) in order to make the 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. This model is a low center of gravity structure with wide range of track and low total height. Therefore, it can be used in a space saving place or a place with torque and a place with high rigidity.

2?Product Feature And Application of the THK HRW12

Miniaturization and heavy load

Automatic centering ability

Radial clearance(Preloading level)

3?Production Details of the THK HRW12

Because the radial clearance of the 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.

The gap between all types of linear guides (except for separating types HR, GSR and gsr-r) is adjusted as specified before delivery, so they do not need to be preloaded.
