Product Description

What this part is

RHP 7305ETSULP4 super precision single-row angular contact ball bearing. Bore: 25 mm. Outside Diameter: 62 mm. Overall Width: 17 mm. Series: 7300, ISO dimension series 03. Number Of Rows: 1. Rolling Elements: Balls. Bore Type: Straight. Closure Type: Open. Country of Origin: United Kingdom.

Decoding the designation

Contact Angle: 25°. Cage Material: Laminated phenolic resin. Cage Type: Machined, outer-ring guided. Preload: Light. Mounting Arrangement: Single universal. Precision Class: RHP P4, ISO Class 4, ABEC 7. The carton carries the same bearing in three schemes: RHP 7305-E-T-SUL-P4, RHP B-series B7305X3TADULEP7, and Fafnir 3MM305WICRDUL. Searchable forms: 7305ETSULP4, 7305 E T SUL P4, 7305-E-T-DUL-P4, 7305E.

What these specs mean in practice

A 25° contact angle carries more thrust and less speed than a 15° execution on the same envelope. Bearing Material: Carbon chrome bearing steel, SAE 52100, through hardened and heat treated for stability and life. Cage Material: Laminated phenolic resin, outer-ring guided, for high-speed quiet running. 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.

Quantity and configuration

Unit Quantity: 1 Pc. Universal face control means the inner and outer rings are ground to the same width and the face relationships are adjusted at manufacture, so two of these mount back-to-back or face-to-face at the same light preload, and tandem-mounted bearings share load equally.

Fitting notes

The high point of radial runout is marked by a burnished spot or small circle on the inner ring face and by a V line on the outer ring diameter. The V line also gives the direction of the contact angle, and points toward maximum axial capacity when load is applied to the inner ring. Item Weight: 0.51 lbs.
