Kerk Motion Products, a manufacturer of non-ball lead screws, has introduced the VHD series, suitable for eliminating drag and wear associated with high pre-load forces. The series anti-backlash assembly is said to provide the maximum load-carrying capability and the highest axial and radial stiffness of any Kerk nut assembly.
Designed for smooth, quiet operation and long life, the VHD assembly
provides low drag torque by making use of the patented Kerk axial
take-up mechanism, creating a stiff spacer which will continually
expand to accommodate the wear which occurs during use.
The self-lubricating series is available in leads from 1.27 mm/.050 in. to 92 mm/3.6 in. and lengths up to 4 m/160 in.. Screws are 303 stainless steel, with Kerk's custom Kerkote TFE extended life coating optional. Assemblies are available cut-to-length or with screws machined to requirements.
