Converts uniform input motion to intermittent output motion, or uniformly decelerated intermittent output motion. The input shaft drives the CAM, and in the area of CAM motion Angle, the work surface of the indexing turntable rotates. When the rotation reaches the area of the CAM line segment, the work surface is stationary. The precise fit of the roller shaft with the CAM provides a locking working position. We increase the design size and use size of the rotating CAM as much as possible to make the indexing turntable run more smoothly. There is a side through hole in the housing to facilitate the cable or tube body wiring. Brake wear is reduced by using the control system of the indexing table, making the indexing table maintenance-free for life.
