Product Description

What this part is

RHP 7002CTDULP4V super precision single-row angular contact ball bearing. Bore: 15 mm. Outside Diameter: 32 mm. Overall Width: 9 mm. Series: 7000, ISO dimension series 10. Number Of Rows: 1. Rolling Elements: Balls. Bore Type: Straight. Closure Type: Open. Country of Origin: United Kingdom.

Decoding the designation

Contact Angle: 15°. Cage Material: Laminated phenolic resin. Cage Type: Machined, outer-ring guided. Preload: Light. Mounting Arrangement: Duplex universal. Precision Class: RHP P4, ISO Class 4, ABEC 7. The carton carries the same bearing in three schemes: RHP 7002-C-T-DUL-P4V, RHP B-series B7002 C T P4S, and Fafnir 2MM9102WI-DUL. Searchable forms: 7002CTDULP4V, 7002 C T DUL P4V, 7002-C-T-DUL-P4V, 7002C.

What these specs mean in practice

Dynamic Load Rating: 6.25 kN, 1405 lbf. Static Load Rating: 3.40 kN, 764 lbf. Limiting Speed, oil/air lubrication: 71,400 r/min. Limiting Speed, grease lubrication: 44,200 r/min. A 15° contact angle carries less thrust and more speed than a 25° execution on the same envelope, which is why this size reaches the speeds above. Effective Load Centre: 7.6 mm. Bearing Material: Carbon chrome bearing steel, SAE 52100, through hardened and heat treated. Maximum Operating Temperature: 120 °C. Minimum Operating Temperature: -30 °C. Internal Clearance: N/A — the light preload is set at manufacture, so the bearing is preloaded rather than clearance-graded. Lubricant: grease or oil. Item Weight: 0.031 kg, 0.07 lbs.

Quantity and configuration

Unit Quantity: 1 Pc. One piece from a factory duplex light-preload pair. Universal face control means the inner and outer rings are ground to the same width, so two of these mount back-to-back or face-to-face at the same light preload, and tandem-mounted bearings share load equally. Axial Preload, duplex light pair: 39 N. Axial Stiffness, duplex light pair: 23 N/µm.

Fitting notes

Abutment Diameter, shaft, d1 min: 17.5 mm. Abutment Diameter, housing, D1 max: 29.5 mm. Housing Abutment D2 max: 30.8 mm. Chamfer r min: 0.3 mm. Chamfer r1 min: 0.15 mm. Internal Free Volume: 1.4 cm³. Pitch Circle Diameter of Lubrication Jets: 21.3 mm. The high point of radial runout is marked by a burnished spot on the inner ring face and by a V line on the outer ring diameter, which also gives the direction of the contact angle.
