Ball Screw Support Bearings


Ball Screw Support Bearings

High-precision angular contact thrust ball bearings for precision ball screws are designed for a wide variety of applications with a range of high rigidity and high load capacity series available.


Lineup Highlights

  • A high rigidity series for machine tools provides high axial rigidity and precise rotation with low drive power.
  • A sealed high rigidity series for machine tools improves life and reliability.
  • A high load capacity series for electric injection molding machines offers longer service life and higher permissible loads through optimized ball diameters and contact angles.

NSKTAC 03 Series Angular Contact Ball Bearings

Reliable NSKHPS bearings with a compact, simplified design for reducing costs.


  • Compact with high load capacity
  • High reliability
    Significantly longer service life compared to standard angular contact ball bearings.
  • Low torque
    An optimized ball bearing design realizes lower torque.
BSBD Series Double-Row Angular Thrust Ball Bearings

Grease-filled NSKHPS bearings with seals and mounting holes help simplify operations. These high-performance double-row angular contact ball bearings come arranged back-to-back (DB) with an integrated outer ring.


  • No need to fill grease
    Bearings come pre-packed with high-performance grease, eliminating difficult and messy grease filling.
  • Easy to mount/dismount
    BSF types feature bolt holes and an extraction groove for easy handling.
  • Options for even longer life/higher rigidity
    Matched DT pairs available for applications with large external loads or where high rigidity and long life are required.



answersNSKTAC Series bearings are specially designed for ball screw support. They provide particularly high precision and high rigidity under large thrust loads.
