RHP7200ETDULP4Angular Contact Ball Bearing Pair – 10 mm ID, 30 mm OD, 9 mm Width, 25° Contact Angle, Light Preload, ABEC 7 / P4, Phenolic Cage, Open.

Product Description

What this part is:

RHP 7200ETDULP4 super-precision angular contact ball bearings, ISO dimension series 02, supplied as a matched duplex pair with a 25° contact angle, light preload, phenolic cages and ABEC 7 / P4 precision. Bore Diameter: 10 mm. Outside Diameter: 30 mm. Overall Width: 9 mm per bearing. Total Width: 18 mm for the pair.

Decoding the designation:

7 — single-row angular contact ball bearing.

2 — RHP dimension series 2, ISO series 02.

00 — bore code 00, 10 mm bore.

E — 25° contact angle. The legacy RHP code for the angle NSK now designates A5.

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

DU — paired unit. Two universally faced bearings supplied and matched as a set, mountable back-to-back, face-to-face or in tandem.

L — light preload. As a back-to-back pair this gives an axial preload of 39 N and an axial stiffness of 41 N/µm.

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