Inch Precision Accuracy Ball Screw Assembly XPR

To obtain optimum performance, it is required that the ball screws machined in their case hardened state. When annealing is applied to the end of the ball screw for machining purposes, the lead accuracy is distorted causing the ball nut to lock or jam on the ball screw.

Nook ball screw assemblies provide ease of application without the need to machine or anneal the ball screw, as all that is required is installation. Nook inch precision ball screw assemblies offer turnkey solutions that only require a power source. All of the elements are available for quick delivery from shelf stock.
