Trapezoidal lead screw DC series

die-cast zincwith nutrolled

The Lead Screw Nut Models DCM and DC are manufactured to meet the standards for 30° trapezoidal threads. The nut is made of a special alloy and die-cast with a precision male thread as its core. As a result, these bearings achieve greater stability in accuracy and higher accuracy and wear resistance than machined lead screw nuts. For the screw shafts to be used with this product, rolled shafts are available as the standard. In addition, cut screw shafts are also available according to the application. Contact THK for details. Structure and Features The lead Screw Nut models DCM and DC are manufactured to meet the standards for the 30° trapezoidal threads. They use a special alloyHigh Strength Zinc Alloy(see) for the nuts and have a precision male thread, formed through die casting, as the core. As a result, these bearings achieve less unevenness in accuracy and higher accuracy and wear resistance than the machined lead screw nuts.For the screw shafts to be used with this product, the rolled shafts are available as the standard. In addition, cut screw shafts are also available according to the application. Contact THK for details. Features of the Special Rolled Shafts The dedicated rolled shafts with the standardized lengths are available for the Lead Screw Nut. Increased Wear Resistance The shaft teeth are formed by cold gear rolling, and the surface of the tooth surface is hardened to over 250 HV and are mirror-finished. As a result, the shafts are highly wear resistant and achieve significantly smooth motion when used in combination with lead screw nuts.
