Series for high load motion control applications

The Kerk VHD series anti-backlash assembly provides 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 assembly provides low drag torque by making use of the 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 also instrumental in combating environmental and noise reduction challenges, as encountered in the packaging industry. The VHD screw does not require grease to operate and therefore reduces noise and dust in the workplace.

Accuracy, reliability and load rating make the series a good replacement for ball screws.

Leads are available from 1.27 to 92 mm and lengths up to 4 m. The series screws are 303 stainless steel, with Kerk’s Kerkote TFE extended life coating optional. Assemblies are available cut to length or with screws machined to user requirements.
