seal up
The sliding block is completely closed from all directions by baffle, gap seal, upper seal and lower double side seal. These seals ensure that the rolling element will not be polluted even in harsh environments.
Double lip seals at both ends of the standard slider ensure that lubricating oil or grease will not be lost from the system.
Preload
Linear circulating roller bearing guide system rue- E the optional preload level is
When the preload has only a very small deviation, the system will achieve the optimal rigidity. When the linear circulating roller bearing guide system leaves the factory, it has been assembled in complete sets, and all parts have been grouped and matched.
The higher the preload, the better the rigidity.
However, preload will affect friction and system life.
friction
The coefficient of friction depends on the ratio of C / P. For no seal, the load ratio C / P = 4 to C / P = 20:
Rue = 0.002 to 0.004
Accuracy grade of linear circulating roller bearing guide system the accuracy grade of linear circulating roller bearing guide system ranges from G0 to G3
