Decoding the designation:

B72 — Schaeffler’s spindle bearing series in the 72 section, which carries more load than the 70 section on the same bore.

7211 — ISO size code. Bore 55 mm, outside diameter 100 mm, width 21 mm.

C — Contact angle 15°.

TPA — Fabric-base laminate phenolic cage, machined.

P4 — Precision Class: ABEC 7 / P4.

UL — Universally matchable. Faces are ground so any two or more bearings pair in back-to-back, face-to-face or tandem arrangement and reach the published preload without shims.
