Ball Screw Support Bearings for High Load Application - NSKTAC-SHR Series The NSKTAC-HR series has been developed for support ball screws operating under high loads. The new NSKTAC-SHR series allow users to maintain high capacity performance with a smaller diameter of the screw shaft end. This will enable a reasonable contact point pressure at the shoulder of the inner ring in the bearing. Product Features • Smaller bore diameter • Reasonable contact point pressure at the inner ring • No need to create a bigger shoulder on the ballscrew shaft Condition Description • High Load • High load capacity in a small envelope design • 5 times longer service life than a standard product • Easy handling • Optimum design for reduced torque • No additional cost required for bigger shaft material • Automotive Production • Machine Tools • Injection Moulding 60 Bearing bore diameter Bearing type symbol Dimension symbols Internal design symbol Cage symbol Arrangement symbol Preload symbol Accuracy symbol
