RHP7206CTSUHP4Angular Contact Ball Bearing – 30 mm ID, 62 mm OD, 16 mm Width, 15° Contact Angle, ABEC 7 / P4, Heavy Preload, Open.

Product Description

What this part is:

RHP 7206CTSUHP4 super precision single-row angular contact ball bearing, 30 x 62 x 16 mm, 15° contact angle, ABEC 7 / P4, heavy preload, universally face-ground. Unit Quantity: 1 Pc.

Decoding the designation:

7 — single-row angular contact ball bearing.

2 — RHP dimension series 2, ISO series 02.

06 — bore code 06, a 30 mm bore.

C — 15° contact angle. The carton’s B-series code X2 and the leading 2 of the Fafnir number 2MM206WI both state the same 15°.

T — machined cage in laminated phenolic resin, outer-ring guided. The Fafnir-scheme cage code CR on the same carton is the same laminated phenolic.

SU — single universal face control. Inner and outer rings are ground to equal width, so two bearings mount back-to-back, face-to-face or in tandem without custom-ground spacers.

H — heavy preload, the highest of RHP’s four standard levels. The B-series UH and the Fafnir SUH on the carton both state heavy preload.

P4 — RHP precision grade P4, ABEC 7. The carton’s EP7 marking is the British Standards form of the same grade.
