A factory-matched pair of SNR 7010 C V DU J84 super-precision angular contact ball bearings. Single row each, 50 mm bore, 80 mm outside diameter, 16 mm width, open on both faces, with a machined phenolic cage.
7010 is the ISO 70 dimension series with bore code 10, giving a 50 mm bore. C is a 15° contact angle. DU marks a duplex set ground together at the factory. J84 is the medium preload class in the NTN-SNR super-precision preload scheme, one step above the J74 light class. This preload family is separate from the SNR J20 to J50 radial clearance codes used on standard bearings.
Basic dynamic radial rating is 29 kN and static radial rating 16.1 kN. A 15° contact angle favours speed and radial stiffness over thrust capacity. Medium preload gives higher axial and radial stiffness than a light-preload set and holds spindle position more firmly under changing load, at the cost of extra friction and running temperature. Limiting speed for the set is 18,000 rpm.
Two pieces, one matched duplex set, 32 mm total width. Mounted back-to-back or face-to-face the set takes thrust in both directions and realises the J84 medium preload; in tandem it takes thrust in one direction at doubled capacity.
The marked ring faces go together in the factory-ground orientation, clamped square against a rigid shoulder so the preload lands as designed. Clamping load passes through the rings. Operating range for the phenolic cage is –40 °C to 120 °C.
Equivalents at the same size, angle, cage and preload include SKF 7010 CD/P4ADGB, FAG B7010-C-T-P4S-DUM, NSK 7010CTYNDUMP4, RHP 7010CTDUMP4 and Fafnir 2MM9110WI-CR-DUM. The same designation at J74 is the light-preload version and is a related size rather than an interchange, because preload sets the stiffness and speed of the assembly.
