RHPAngular Contact Bearing – 65 mm ID, 120 mm OD, 23 mm Width, Open, 40° contact angle.

Product Description

What this part is: RHP 7213BJ single-row angular contact ball bearing. Bore: 65 mm. Outside diameter: 120 mm. Width: 23 mm. Series: 7200 (ISO 72xx medium series). Contact Angle: 40°. Open on both faces. Precision Class: ABEC 1 / P0, which is RHP grade EP1, the standard tolerance class. Country of origin on this item: United Kingdom. Decoding the designation: B: 40° contact angle in the RHP designation system. J: pressed steel cage. Bore Type: Straight. Cage Type: Pressed. Cage Material: Steel. The ISO base number for this envelope is 7213. What these specs mean in practice: A 40° contact angle is the highest of the standard angular contact range, so this execution carries the largest one-directional thrust load available on a 65 x 120 x 23 mm envelope and gives up top speed to do it. It is the angle chosen where axial load dominates over radial — pump and compressor shafts, worm drives, vertical shafts, and screw-jack and feed-screw locations. The pressed steel cage keeps mass and cost down and suits the moderate speeds a standard-class 40° bearing runs at. Quantity and configuration: One bearing. Unit Quantity: 1 Pc. A single angular contact bearing takes thrust in one direction, so a shaft loaded both ways runs two of them opposed, back-to-back or face-to-face. Interchange guidance: 40° bearings in the same 65 x 120 x 23 mm size: SKF 7213 BEP, FAG 7213-B-XL-TVP and NSK 7213B. SKF 7213 BECBM also matches in angle and size but has a machined brass cage. Cage material differs across these designations — polyamide on the BEP and TVP forms, machined brass on the BECBM — which changes the speed and temperature ceiling. Other contact angles in the same size: 7213C or 7213 CD at 15°, and 7213E or 7213 ACD at 25°.
