THK DCMB Change Nut

The THK DCMB Change Nut is designed to convert linear motion into rotary motion, or rotary motion into linear motion. It has a large lead and can create a fast-feed mechanism with low-speed rotation. THK specifies an efficiency of approximately 70%.

The DCMB Change Nut is made from high-strength zinc alloy. This material provides good wear resistance and high load capacity. The mating screw shaft has hardened, mirror-finished teeth for smooth operation.

The DCMB Series includes miniature and long-nut designs. Models are available from DCMB 8T to DCMB 50, with dynamic permissible thrust from 863 to 57,100 N, depending on the model.
