TBR series linear guides are always rolling guides. Rolling steel balls reciprocate infinitely between the slider and the guide rail. The load platform can easily move linearly with high precision along the track. Compared with the traditional machine tool guide, the friction coefficient of the rolling guide can be reduced to 1/50 of the original. Since the starting friction is greatly reduced, the occurrence of invalid motion is relatively reduced, so high-precision feeding and positioning can be achieved.
