Kerk NTG Adjustable Anti-backlash Nut Assembly – 303 Stainless Steel Acme Lead Screw

The patented NTG Series offers a cost effective anti-backlash assembly for applications requiring precise positional accuracy, repeatability, and smoothness. The NTG has been developed specifically for demanding applications that require zero backlash with minimal drag torque. With its compact size and no moving components, the NTG can also be easily incorporated into customer specified, custom molded parts.

An integral part of the NTG design is the ability to manually adjust the drag torque setting to match specific requirements of the application. This drag torque can also be set at the factory to meet individual customer specificatons. This is especially effective with fine leads.

The standard NTG unit utilizes a self-lubricating polyacetal nut on a precision rolled 303 stainless steel acme lead screw. End machining to customer specifications and Kerkote® TFE screw coating are optional.
