RHP 7304-A-T-DUL-P4 super-precision angular contact ball bearing, 20 x 52 x 15 mm, 30° contact angle, ABEC 7 / P4. Two pieces from a factory matched set, ground for light preload when mounted as a pair.
7304 — ISO series 03 angular contact ball bearing, 20 mm bore, 52 mm outside diameter, 15 mm width.
A — 30° contact angle.
T — machined cage. The carton’s B-series string resolves it to TA: a one-piece machined laminated phenolic cage, outer-ring centred.
DU — duplex universal. The faces are ground so that any two bearings from the range mount back-to-back, face-to-face or in tandem.
L — light preload.
P4 — ISO precision class 4, equivalent to ABEC 7.
EP7 — the same class written in RHP’s B-series scheme, equivalent to ABEC 7.
