Uses special alloys! Bearings with minimal variation in precision, high accuracy, and excellent wear resistance.
The "Screw Nut" DCM type/DC type is manufactured according to the standards of 30-degree trapezoidal threads. The nut is made from a special alloy and is die-cast molded using a precision male thread as a core. As a result, unlike machined products, it has less variation in precision and is a high-precision bearing with excellent wear resistance. The screw shafts that are combined are standardized through forming. Additionally, we also manufacture cutting screw shafts and grinding screw shafts according to your application, so please feel free to inquire. 【Features】 ■ Manufactured according to the standards of 30-degree trapezoidal threads ■ Made from a special alloy ■ Less variation in precision, high precision, and excellent wear resistance *For more details, please refer to the PDF materials or feel free to contact us.

basic information
【Features of the Dedicated Rolling Shaft】 For the screw nut, a dedicated rolling shaft with standardized length is available. ■ Improved Wear Resistance Due to cold rolling, the tooth profile of the shaft is formed, resulting in a surface hardness of over 250HV and a smooth mirror finish, which provides excellent wear resistance. The movement resulting from the combination of screw nuts is also extremely smooth. ■ Enhanced Mechanical Properties The internal structure of the tooth surface of the rolled shaft exhibits fiber flow along the contour of the tooth profile, resulting in a very dense structure at the root of the tooth, which increases fatigue strength. ■ Additional Processing of the Shaft End Support Since the shaft is rolled, additional processing such as turning and milling for the support bearing at the shaft end can be easily performed. The screw nut (DC/DCM) and screw shaft CS are sold separately. Please use them as a set. *For more details, please refer to the PDF document or feel free to contact us.
