Product Description

What this part is

RHP 7002CTDULP4 super-precision angular contact ball bearing, supplied as a universally ground matched pair. Series: 7000, ISO dimension series 10. Bore: 15 mm. Outside Diameter: 32 mm. Overall Width: 9 mm per bearing. Contact Angle: 15°. Precision Class: P4. Precision Rating: ABEC 7. Bore Type: Straight. Number Of Rows: 1. Rolling Elements: Ball. Bearing Material: Chrome bearing steel. Closure Type: Open. Item Weight: 0.07 lbs per bearing.

Decoding the designation

The carton carries this bearing in four numbering schemes, and all four give the same contact angle. RHP 7002 C T DUL P4, FAG B7002 C T P4S, SKF 7002 CD/P4ADGA and Fafnir 2MM9102WI DUL. Contact Angle: 15°. Cage Material: Phenolic. Cage Type: Machined, outer ring guided. The cage is laminated phenolic resin riding on the outer ring land. Preload: Light. Grouping: DU, a universally ground paired unit. Precision Class: P4, published by RHP as EP7 under BS292 and equivalent to ABEC 7 and ISO Class 4.

What these specs mean in practice

Dynamic Load Rating: 6.25 kN. Static Load Rating: 3.4 kN. Limiting Speed: 71,400 rpm on oil-air lubrication and 44,200 rpm on grease, quoted for a single bearing under spring preload. Preload Force: 29 N per bearing at the light class. A 15° contact angle favours speed and radial stiffness over thrust capacity, which is why this execution runs roughly 20% faster than the 25° version of the same envelope. The laminated phenolic cage is light, quiet and self-lubricating. Max Temp: 120°C. Min Temp: -30°C.

Mounting dimensions

Minimum shaft abutment diameter: 17.5 mm. Maximum housing abutment diameter: 29.5 mm. Maximum outer ring abutment diameter: 30.8 mm. Bore chamfer r min: 0.3 mm. Outer chamfer r1 min: 0.15 mm.

Quantity and configuration

Unit Quantity: 2 Pcs. Two universally ground bearings supplied as a matched DUL pair at light preload. Mounting Arrangement: Universal — universally ground faces allow the pair to be set back-to-back, face-to-face or in tandem.

Interchange guidance

Cross-Reference 1: SKF 7002 CD/P4ADGA. Cross-Reference 2: FAG B7002-C-T-P4S-DUL. Cross-Reference 3: NSK 7002CTRDULP4. Cross-Reference 4: Fafnir 2MM9102WICRDUL. Each is a 15 x 32 x 9 mm, 15°, phenolic-caged super-precision execution at the equivalent tolerance class. A 7002 A5 carries a 25° contact angle on the same envelope and is a related size rather than a direct substitution.
