A matched duplex pair of RHP 7201 super-precision angular contact ball bearings, 15° contact angle, phenolic cage, universally ground for light preload. Each bearing is 12 mm bore x 32 mm OD x 10 mm wide, so the pair stacks to 20 mm overall. Small-bore super-precision like this goes into high-speed grinding spindles, instrument spindles, small ball screw ends and precision indexing heads.
7201 is the ISO angular contact envelope, 12 x 32 x 10 mm. C is the 15° contact angle in the RHP / Timken scheme. T is a phenolic cage. DUL is duplex, universally ground, light preload. P4 is ABEC 7 tolerance class. V is an RHP variant suffix carried on the carton and kept as a search term.
15° is the high-speed, low-thrust end of the angular contact range: excellent for speed and radial load, modest axial capacity compared with a 25° or 30° bearing of the same size. Light preload keeps friction and heat down, which is what a small bearing running fast needs. The phenolic cage is light, quiet and self-lubricating.
Bore: 12 mm. Outside diameter: 32 mm. Width: 10 mm each bearing. Total width mounted as a pair: 20 mm. Contact angle: 15°. Tolerance class: P4 / ABEC 7. Preload: light. Cage: phenolic. Rows: single row each, mounted as a duplex pair. Closure: open. Dynamic load rating: 7.7 kN / 1731 lbf. Static load rating: 4.15 kN / 933 lbf. Limiting speed: 40000 rpm. Mass: 0.08 lbs.
Two bearings, supplied as the matched set. Universally ground rings mean the pair can be arranged back-to-back (DB), face-to-face (DF) or in tandem (DT) and still produce the intended light preload with no spacer.
Direct equivalents are 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.
