Product Description

What this part is

A matched duplex pair of RHP 7201 super-precision angular contact ball bearings, 15° contact angle, phenolic cage, universally ground for light preload. Bore Diameter: 12 mm. Outside Diameter: 32 mm. Width: 10 mm each bearing. Total Width, mounted as a pair: 20 mm. Small-bore super-precision like this goes into high-speed grinding spindles, instrument spindles, small ball screw ends and precision indexing heads.

Decoding the designation

7201 — the ISO angular contact envelope, 12 x 32 x 10 mm.

C — 15° contact angle in the RHP / Timken scheme.

T — phenolic cage.

DUL — duplex, universally ground, light preload.

P4 — ABEC 7 tolerance class.

What these specs mean in practice

Contact Angle: 15°. Precision Class: P4 / ABEC 7. Preload: Light. Cage Material: Phenolic. Number Of Rows: 1 per bearing, mounted as a duplex pair. Closure Type: Open. A 15° angle is the high-speed, low-thrust end of the angular contact range: excellent for speed and radial load, with modest axial capacity compared with a 25° or 30° bearing of the same size. Light preload keeps friction and heat down, which a small bearing running fast needs. The phenolic cage is light, quiet and carries oil in its surface.

Quantity and configuration

Unit Quantity: 2 Pcs, supplied as the matched set. Universally ground rings let the pair be arranged back-to-back (DB), face-to-face (DF) or in tandem (DT) and still produce the intended light preload with no spacer.

Interchange guidance

7201 15° ABEC 7 light-preload universally ground duplex pairs, including the NSK 7201CTYDULP4 and B7201 forms and RHP’s own 7201-C-T-DUL-P4. Related but not interchangeable: 7201A5 (25°) and 7201A (30°) in the NSK scheme, and DUM / DUH medium and heavy preload variants.
