RHP7008CTSULP4Angular Contact Ball Bearing – 40 mm ID, 68 mm OD, 15 mm Width, 15° Contact Angle, Light Preload, ABEC 7 / P4.

Product Description

What this part is:

RHP 7008-C-T-SUL-P4 super-precision single-row angular contact ball bearing, universally ground for matching. Unit Quantity: 1 Pc.

Decoding the designation:

7 — single-row angular contact ball bearing.

0 — RHP dimension series 0, ISO series 10. This is the 70xx light section.

08 — bore code, multiplied by five for a 40 mm bore.

C — 15° contact angle.

T — laminated phenolic resin cage, guided on the outer ring. Maximum recommended operating temperature 120 °C.

SU — single universal. One bearing with universal face control, ground so any two of the same designation combine as a matched pair at the stated preload.

L — light preload. Axial preload 120 N and axial stiffness 51 N/µm when two are paired.

P4 — RHP precision grade P4: ISO Class 4, ABEC 7, British Standard EP7.
