THK Change Nut DCMA Type / DCMB Type
Lead screw suitable for fast-forward mechanism.
The Change Nut DCMA type/DCMB type is a change nut with a lead angle of 45° that is not easily obtained through machining. It can efficiently convert linear motion to rotary motion and rotary motion to linear motion at a rate of 70%, and due to its large lead, it is ideal for creating fast feed mechanisms at low rotational speeds. The multi-start screw shafts that are combined with the change nut are formed through cold forging. The surface hardness of the tooth profile is processed to over 250HV, and with a mirror finish, the movement combined with the change nut is extremely smooth and has excellent wear resistance. Additionally, the DCMA40 type and DCMB40 type or higher are combined with cutting screw shafts. The miniature change nut is molded from oil-impregnated plastic, which provides wear resistance and particularly excellent lubrication performance without oil. Moreover, it can maintain this performance for a long time, making it possible to be maintenance-free. For more details, please contact us.
