Product Description

What this part is:

RHP 7211-E-T-SUL-P4 single-row super precision angular contact ball bearing, 55 x 100 x 21 mm, 25° contact angle, universally ground faces for pairing. Unit Quantity: 1 Pc.

Decoding the designation:

72 — ISO dimension series 02, the medium section of the RHP super precision angular contact range.

11 — bore code, 55 mm.

E — 25° contact angle, the legacy RHP code for the execution now designated A5. X3 in the RHP B-series string and the leading 3 in the Fafnir string carry the same angle.

T — machined laminated phenolic cage, outer-ring guided.

SU — universal face control, a face-ground property of the bearing.

L — light preload class for a universal pair.

P4 — RHP tolerance class P4, equivalent to BS 292 EP7 and ABEC 7.
