SNFAVX35-7CE1DUMAngular Contact Ball Bearing – 35 mm ID, 62 mm OD, 14 mm Width, Open, 15°, Medium Preload, Universal Duplex Pair

Product Description

What this part is

SNFA VX35-7CE1DUM super-precision angular contact ball bearing, supplied as a universally ground matched duplex pair. Bore 35 mm, outside diameter 62 mm, width 14 mm per bearing, 28 mm across the pair. ISO equivalent size 7007. SNFA is part of the SKF group.

Decoding the designation

VX is the SNFA high-speed angular contact series. 35 is the bore in millimetres. The 7 is the precision class, ABEC 7 to ISO P4. CE1 is the high-speed execution at a 15° contact angle. DUM is a duplex universal set at medium preload.

What these specs mean in practice

The 15° contact angle favours speed and radial stiffness over thrust capacity, which is what supports the 31,000 rpm limiting speed on a 35 mm bore. Medium preload raises axial and radial stiffness relative to a light-preload set, at the cost of a little speed and more heat. The phenolic cage is light and runs well with oil-mist and oil-air lubrication. Dynamic capacity is 24.3 kN and static capacity 15.0 kN.

Quantity and configuration

Two bearings, matched as one set, 0.35 lbs per bearing. Universal grinding allows back-to-back, face-to-face or tandem arrangement, with preload established as the ground ring faces are clamped together.

Preload and clearance

Medium preload, ground into the ring faces. A preloaded matched pair has no operating radial internal clearance, so clearance classes such as CN do not apply.

Fitting notes

The outer rings carry a mark across the outside diameter; the marks are aligned to hold the intended arrangement. Shaft and housing seats are held to matching precision tolerances, and both bearings are clamped as one unit against a common shoulder.

Interchange guidance

FAG B7007-C-T-P4S-DUM is a same-specification interchange at 15°, phenolic cage, duplex universal medium preload. Fafnir 2MM9107WI-CR-DUM matches size, angle, cage and arrangement. SKF 7007 CD/P4ADGB shares the envelope and angle but is supplied as a fixed back-to-back pair, so it is a related arrangement.
