Product Description

What this part is:

RHP 7203ETDUMP4V super-precision single-row angular contact ball bearing, ISO dimension series 02, 17 mm bore x 40 mm outside diameter x 12 mm width. One half of a factory duplex pair, universally faced. Unit Quantity: 1 Pc.

Decoding the designation:

7203 — single-row angular contact ball bearing, dimension series 02, bore code 03 = 17 mm.

E — 25° contact angle (legacy RHP code, current NSK A5).

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

DU — paired unit, universally faced for back-to-back, face-to-face or tandem mounting.

M — medium preload. As a back-to-back pair this gives an axial preload of 200 N and an axial stiffness of 87 N/µm.

P4 — ISO Class 4, ABEC 7, British Standard EP7.

1/2PR — one half of the factory pair.
