RHP7002-C-T-DUM-P4Angular Contact Ball Bearing – 15 mm ID, 32 mm OD, 9 mm Width, 15° Contact Angle, ABEC 7 / P4, Medium Preload, Open.

Product Description

What this part is:

RHP 7002-C-T-DUM-P4 super precision single-row angular contact ball bearing, 15° contact angle, medium preload, ABEC 7 / P4, open, machined phenolic outer-ring guided cage. Unit Quantity: 1 Pc, one bearing from a factory-matched duplex pair (-1/2PR).

Decoding the designation:

7 — single-row angular contact ball bearing.

0 — RHP dimension series 0, ISO series 10.

02 — bore code 02, a 15 mm bore.

C — 15° contact angle. The carton’s B-series code X2, the Fafnir number 2MM9102WI and the FAG and SKF cross-numbers B7002-C-T-P4S and 7002 CD/P4A all state the same 15°.

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

DU — duplex universal. The factory set is two bearings ground together with the bores and outside diameters size-graded to share load evenly.

M — medium preload. The SKF cross-number on the same carton carries DGB, SKF’s own medium preload code.

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

-1/2PR — half a pair. Unit Quantity: 1 Pc.
