Decoding the designation:

35TAC72 — 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 35TAC72 is a 35 mm bore in a 72 mm outside diameter.

A — the first design generation within the TAC family.

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 35 mm bore seats on the screw journal and the 72 mm outside diameter locates in the support housing bore. Overall Width: 15 mm per bearing, which sets the axial space each piece occupies in a stacked arrangement.
