RHP7305ATSUHP4Super-Precision Angular Contact Ball Bearing – 25 mm ID, 62 mm OD, 17 mm Width, Open, 15° Contact Angle, Heavy Preload, ABEC 7

Product Description

What this part is:

RHP 7305ATSUHP4 super-precision single-row angular contact ball bearing, ISO dimension series 03 (the medium series), with a 15° contact angle, heavy preload, a machined phenolic cage and P4 / ABEC 7 precision. Bore: 25 mm. Outside Diameter: 62 mm. Overall Width: 17 mm.

Decoding the designation:

7305 — ISO size 25 x 62 x 17 mm, series 7300.

SUH — single universal at heavy preload. Inner and outer rings are the same width and flush ground, so any two of these bearings clamp back-to-back or face-to-face at the rated preload with no custom spacer, and share load equally in tandem.

P4 — ISO Class 4, equivalent to BS292 EP7 and ABEC 7.

2MM305WICRUH — Fafnir carton designation: 2MM = 15° contact angle, CR = phenolic outer-ring-guided cage, UH = universal heavy preload.

B7305X4TADUHEP7 — RHP B-series carton designation; EP7 = P4.

Dimensions and mounting:

Recommended shaft fit at P4 for a 25 mm seat: +2 to −2 µm, a mean 2 µm interference. Recommended housing fit for a locating position at 62 mm: +5 to 0 µm, a mean 5 µm clearance. The high point of radial runout is marked on the bearing: a small circle or burnished spot on the inner ring face, and a V line on the outer ring outside diameter, which also shows the direction of the contact angle.

Compatibility and replacement:

Carton designations carried on this part: B7305X4TADUHEP7 and 2MM305WICRUH. Cross-reference: Timken Fafnir 2MM305WICRUH. A 7305 in the 25° or 40° execution shares this 25 x 62 x 17 mm envelope and is a related size.
