Rolling Elements: Ball. Number Of Rows: 1. Bore Type: Straight. Closure Type: Open. Bearing Material: Bearing steel. Series: TAC.

Decoding the designation

25TAC62 — NSK’s ball screw support angular contact thrust series. The leading number is the bore in millimetres and the number following TAC is the outside diameter in millimetres, so 25TAC62 is a 25 mm bore in a 62 mm outside diameter.

B — the second design generation within the TAC family.

SU — single, universally ground. The ring faces are ground so that the bearing can be set against another of the same execution in any orientation to build a matched stack.

What these specs mean in practice

Ball screw support bearings carry thrust along the screw axis and hold the screw in axial position under reversing load. The 25 mm bore seats on the screw journal and the 62 mm outside diameter locates in the support housing bore. Overall Width: 15 mm, which sets the axial space each bearing occupies in a stacked arrangement.

Quantity and configuration

Unit Quantity: 1 Pc. Universally ground faces allow this bearing to be combined with further pieces of the same execution.
