More Details

Roller screw high load ratings and extreme performance characteristics place large demands on end support units. Nook Industries has developed support units capable of handling these demands.

Nook series EZRF end support units are matched to the roller screw (see dimension table below) and are designed to provide high load carrying capacity, precision, speed, rigidity, low friction, and ease of maintenance and installation. EZRF supports include a SFZ locknut.

Note: When selecting the bearing support for an application with high axial loads, the capacities of the bearings and locknuts must be considered. See page 207 of our Precision Screw Assemblies Catalog.
