The assembly offers maximum load-carrying capability and high axial and radial stiffness. The leadscrew requires no grease to operate and, therefore, reduces noise and dust. Available leads are 1.27 mm/0.050 in. to 92 mm/3.6 in. and lengths up to 4 m/160 in.

The screws are manufactured from 303 stainless steel and can be coated with the optional Kerkote TFE extended-life coating.
