An RHP 7912C-T-SUL-P4 super-precision angular contact ball bearing with a 60 mm bore, an 85 mm outside diameter and a 13 mm width. It has a phenolic cage and is single universally ground for light preload. This is the 71912 thin-section size.
7912: 79 thin-section angular contact series, equivalent to 71912: 60 mm bore, 85 mm OD, 13 mm width. C: 15° contact angle in the RHP scheme. T: phenolic cage. SUL: single universally ground, light preload. P4: precision class 4, equivalent to ABEC 7.
A 15° contact angle keeps the load line close to radial, which limits centrifugal ball loading and lets the bearing run fast, and the thin 79-series section keeps the outside diameter small for a given bore — useful where a spindle housing is tight. The phenolic cage is light and self-lubricating, so it runs quietly at speed and tolerates marginal lubrication, with a lower temperature ceiling than brass. Universal grinding means the faces are finished so the bearing can be paired with another of the same designation into a light-preload set, in back-to-back, face-to-face or tandem orientation, without shims.
Bore: 60 mm (2.3622 in). Outside diameter: 85 mm (3.3465 in). Width: 13 mm (0.5118 in). Contact angle: 15°. Preload: light (L). Precision class: P4, ABEC 7. Cage material: phenolic. Number of rows: 1. Rolling elements: steel balls. Closure: open. Grinding: single universally ground.
Supplied as 1 Pc, a single universally ground bearing.
Genuine equivalents are 15° ABEC 7 universally ground light-preload bearings in the same 60x85x13 mm envelope: FAG B71912-C-T-P4S-UL, NSK 7912CTRSULP4, SKF 71912 CD/P4A in light preload and Fafnir 2MM9112WI-SUL. The 25° build of this size, coded E by RHP and A5 by NSK, is a related size rather than an interchange, and medium or heavy preload versions change spindle stiffness and running temperature.
