RHP7310-C-T-DUM-P0Angular Contact Ball Bearing — 50 mm ID, 110 mm OD, 27 mm Width, 15° Contact Angle, Medium Preload, Machined Phenolic Cage, Open

Product Description

What this part is:

RHP 7310-C-T-DUM-P0 angular contact ball bearing. Bore Diameter: 50 mm. Outside Diameter: 110 mm. Overall Width: 27 mm. Contact Angle: 15°. Precision Class: ABEC 1 / P0. Rolling Elements: Ball. Number Of Rows: 1. Bore Type: Straight. Closure Type: Open. Bearing Material: Bearing steel. Series: 7300.

Decoding the designation:

7310 — ISO series 03 angular contact ball bearing, 50 mm bore, 110 mm outside diameter, 27 mm width.

C — 15° contact angle. The carton’s B-series code X2 states the same 15°.

T — machined cage. The carton’s B-series string resolves it to TA: a one-piece machined laminated phenolic cage, outer-ring centred.

DU — duplex universal. The faces are ground so that any two bearings from the range mount back-to-back, face-to-face or in tandem.

M — medium preload.

P0 — ISO normal precision class, written EP1 in RHP’s B-series scheme.

What these specs mean in practice:

Contact Angle: 15°. A 15° angle keeps the load path close to radial, which raises the speed a pair will run at and lowers the thrust it will take compared with a 25° or 30° execution of the same envelope.

Cage Material: Phenolic. Cage Type: Machined, outer-ring guided. A laminated phenolic cage is light, runs against the outer-ring land and tolerates high cage speeds.

Preload: Medium. A medium preload raises stiffness over a light-preload set at the cost of more heat generation at a given speed.

Precision Class: ABEC 1 / P0. Normal-class ring tolerances, combined here with the machined phenolic cage and universal face grinding of the precision range.

Mounting data:

Mounting Arrangement: Duplex, universally ground. Bore Type: Straight. Snap Ring Included: No.

Quantity and configuration:

Unit Quantity: 2 Pcs. Two pieces from a factory matched set, ground for medium preload when mounted as a pair.

Interchange guidance:

Same 50 x 110 x 27 mm envelope at a 15° contact angle: NSK 7310CTRDUM, Koyo 7310C, NTN 7310C, and the higher-class FAG B7310-C-T-P4S and SKF 7310 CD/P4A. The 25°, 30° and 40° executions of the 7310 envelope split the load differently and are not a substitution.
