RHP7004ETSULP4ASuper-Precision Angular Contact Ball Bearing – 20 mm ID, 42 mm OD, 12 mm Width, Open, 25° Contact Angle, Light Preload, ABEC 7

Product Description

What this part is:

RHP 7004ETSULP4A super-precision single-row angular contact ball bearing, ISO dimension series 10, 25° contact angle, single universal (face-ground for pairing). Unit Quantity: 1 Pc.

Decoding the designation:

7004 — single-row angular contact ball bearing, ISO dimension series 10, bore code 04 = 20 mm bore.

E — 25° contact angle.

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

SU — single universal. Rings are the same width and flush ground, so any two of these bearings pair back-to-back or face-to-face at the rated preload.

L — light preload. In a back-to-back pair this gives an axial preload of 78 N and an axial stiffness of 68 N/µm.

P4 — ISO Class 4, ABEC 7, BS292 EP7.
