Ball Screw Support Bearings

NSKHPS: Reliability has been improved by focusing on material cleanliness, which has the biggest impact on bearing life, by employing NSK’s proprietary material evaluation technology. The dynamic load rating has been improved by 5% compared with that of conventional bearings. The NSKTAC C Series features high axial rigidity and is suitable for machine tool feeding mechanisms, while the NSKTAC 03 Series with its high axial load capacity is well suited for the support of large ball screws in high-load drive applications such as electric injection molding machines. With these series, users can achieve much lower torque and higher accuracy than with roller bearings.
