Overview

NSK PSS1010N1D0221 Support Unit is a pre-assembled bearing housing that carries the ends of a ball screw or lead screw shaft. Supplied as fixed-side and support-side units, it locates the shaft axially and radially so the drive maintains accuracy under load, simplifying assembly of linear axes.

The unit combines a machined housing block with angular contact or deep groove bearings, a lock nut, and seals, matched to a screw shaft end diameter. Fixed-side units carry axial thrust with preloaded angular contact bearings, while support-side units allow thermal elongation through a floating bearing.

Key features

Pre-assembled, ready-to-mount bearing housing
Fixed- and support-side types for both shaft ends
Preloaded bearings for axial rigidity and accuracy
Sized to standard ball screw shaft ends

Typical applications

Ball screw and lead screw supports
CNC and automation linear axes
Electric actuator assemblies
Positioning stages and slides

Selection guidance

Match the screw shaft end diameter and mounting pattern, then verify fixed/support type, bearing arrangement, and required axial rigidity.
