Product Description

What this part is

RHP 7304-A-T-DUL-P4 super-precision angular contact ball bearing. Bore Diameter: 20 mm. Outside Diameter: 52 mm. Overall Width: 15 mm. Contact Angle: 30°. Precision Class: ABEC 7 / P4. Rolling Elements: Ball. Number Of Rows: 1. Bore Type: Straight. Closure Type: Open. Bearing Material: Bearing steel. Series: 7300.

Decoding the designation

7304 — ISO series 03 angular contact ball bearing, 20 mm bore, 52 mm outside diameter, 15 mm width.

A — 30° contact angle.

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.

L — light preload.

P4 — ISO precision class 4, equivalent to ABEC 7.

EP7 — the same class written in RHP’s B-series scheme, equivalent to ABEC 7.

What these specs mean in practice

Contact Angle: 30°. A 30° angle puts more of the load path along the shaft axis than a 15° or 25° execution of the same envelope, so a pair carries a higher thrust load and a lower radial one.

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: Light. A light preload removes internal play with the least axial force, holding running temperature down at speed.

Precision Class: ABEC 7 / P4. Tighter bore, outside diameter and running-accuracy tolerances than a standard-class bearing.

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 light preload when mounted as a pair.

Interchange guidance

Same 20 x 52 x 15 mm envelope at a 30° contact angle: NSK 7304ATRDULP4 in the same super-precision class, and the standard-precision Koyo 7304 and NTN 7304. The 15° and 40° executions of the 7304 envelope are a different load split and are not a substitution.
