DCMA Nut

Short Nut
This model is capable of easily converting linear motion to rotary motion and vise versa with 70% efficiency. Since the lead is large, it is optimal for building a fast feed mechanism with low speed rotation.

Note 1: The permissible dynamic torque (T) or permissible dynamic thrust (F) is the value at which the contact surface pressure on the screw tooth surface is 9.8 N/mm2. The maximum axial load (both when stopped and during operation) is set to the dynamic permissible thrust or below, and it must be selected while taking into consideration the desired safety factor.For more detailed specifications, please download the Product Catalog with the link in the Downloads section of this product page.
