RHP 7012-C-T-DUM-P4, a matched duplex pair of single-row angular contact ball bearings. Boundary dimensions 60 mm bore × 95 mm outside diameter × 18 mm width per bearing.
70 – single-row angular contact ball bearing, ISO dimension series 10
12 – bore code, 12 × 5 = 60 mm bore
C – 15° contact angle in the RHP scheme
T – phenolic cage
DU – duplex, a pair ground to run together
M – medium preload
P4 – ABEC 7 precision class
B7012X2TADUMEP7 – the same bearing in the RHP B-series scheme, where X2 = 15° and EP7 = P4
A 15° contact angle favours speed and radial stiffness over thrust capacity, which is why it is the usual machine-tool spindle angle. Mounted as a duplex pair the set locates the shaft in both directions under a built-in medium preload, so the ring faces are ground with a matched offset and the two bearings clamp against each other rather than against a shim stack. Medium preload gives higher axial and radial stiffness than a light-preload set and generates more heat at the same speed. ABEC 7 controls bore, outside diameter and running accuracy to super-precision limits.
Bore: 60 mm (2.3622 in)
Outside diameter: 95 mm (3.7402 in)
Width: 18 mm (0.7087 in) per bearing
Total width mounted: 36 mm (1.4173 in)
Contact angle: 15°
Rows: 1 per bearing
Preload: medium (M)
Precision class: P4 (ABEC 7), RHP equivalent EP7
Cage: phenolic
Closure: open
2 Pcs, one matched duplex pair.
The pair mounts as a unit in the orientation marked on the outer rings, ground faces together, so preload comes from the matched ring-face offset rather than from clamp-up force. Full preload develops once the inner rings are clamped solid against the shaft shoulder and nut and the outer rings against the housing shoulder.
Same-spec 15° medium-preload duplex equivalents in other schemes: RHP B-series B7012X2TADUMEP7, Fafnir 2MM9112WI-CR-DUM, NSK 7012CTRDUMP4, FAG B7012-C-T-P4S-UM. Light-preload DUL and heavy-preload DUH forms, the 25° 7012-E form, and single SU bearings are related sizes in the same 60 x 95 x 18 mm envelope rather than interchanges.
