Kerk KHD Series Anti-Backlash Lead Screw Assemblies

KHD Series Anti-Backlash Lead Screw Assemblies The Kerk KHD Series anti-backlash assembly makes use of Kerk’s patented AXIAL TAKE-UP MECHANISM to provide backlash compensation. The unique split nut with torsional take-up provides increased load capacity and axial stiffness over comparably sized ZBX units. Though high in axial stiffness, the assembly is very low in frictional drag torque (1-3 oz. in.). The anti-backlash mechanism in the KHD unit eliminates the need for load compensating preload forces. The assembly consists of a 303 stainless steel screw mated with a self-lubricating polyacetal nut. End machining to customer specifications and TFE screw coating are optional. Sizes/Leads Available: – Screw Diameter” 3/16″ (9.5mm) – Leads from 0.02″ (0.6mm) to 1.5″ (38mm) – Dynamic Loads to 20 lbs. (10kg)
