RHP7907ETSULP4Super Precision Angular Contact Ball Bearing – Straight Bore, 35 mm ID, 55 mm OD, 10 mm Width, Open, 25° Contact Angle, Light Preload, ABEC 7.

Product Description

What this part is:

RHP 7907ETSULP4 super precision angular contact ball bearing, ISO dimension series 19, single universal, light preload. 35 mm bore, 55 mm outside diameter, 10 mm width, 25° contact angle. Unit Quantity: 1 Pc.

Decoding the designation:

7907 — ISO dimension series 19, 35 x 55 x 10 mm. The ISO 719 family, so 7907 and 71907 designate the same bearing.

E — RHP 25° contact angle execution, catalogued as A5.

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

SU — single universal: the bearing pairs with another of the same execution back-to-back or face-to-face.

L — light preload.

P4 — tolerance class P4, equivalent to ABEC 7 and ISO Class 4.

B7907X3 — RHP B-series form of the number; X3 is the 25° code.

3MM9307WICRSUL — Fafnir designation on the same bearing; 3MM is the 25° prefix and the 9300 series maps to ISO 719xx.
