01 · Description

What the bearing is for

The 35TAC72CSUHPN7C is a high-precision single-row NSK angular contact ball bearing from the BSTC series for supporting ball screws with a 35 mm bore. It is used in larger CNC machining centres where a combination of high axial rigidity and accurate positioning is required.

The 60° contact angle optimises the bearing's ability to carry the axial load generated by the ball screw during axis movement. The PN7C precision class ensures minimal run-out and stable thermal behaviour even during long operating cycles.

The universal SUHP design allows mounting in any paired configuration without selection.
