CMP SERIES Anti-Backlash Lead Screw Nut - for Light Loads, Compact Design

Part Number Construction

Kerk CMP Anti-backlash Nut Assembly - 303 Stainless Steel Acme Lead Screw

The Kerk® CMP Series anti-backlash lead screw assembly utilizes a general purpose self-compensating nut in an exceptionally compact package. This allows equipment designers to utilize smaller assemblies without sacrificing stroke length. The CMP anti-backlash nut design is also ideally suited for applications using grease or oil.

The standard CMP Series assembly utilizes a self-lubricating acetal nut, axially preloaded, on a 303 stainless steel screw. End machining of the lead screw to customer specifications and Kerkote® or Black Ice™ TFE screw coating are optional. Various axial compression springs are also available, depending on application requirements. Please consult factory for details.
