A Fafnir 3MM9107WI-SUL super-precision angular contact ball bearing, 35 mm bore by 62 mm outside diameter by 14 mm wide, single universally ground at light preload. Fafnir is Timken’s super-precision line.
The 3MM prefix sets a 25° contact angle, which the 7007E designation confirms independently, and the MM prefix carries P4S precision, equivalent to ABEC 7/9. The leading 9 in 9107 places the bearing in the ISO 70 light dimension series, giving an ISO base number of 7007, and the 07 size code gives a 35 mm bore. WI marks the super-precision angular contact family and SUL a single universally ground bearing at light preload.
A 25° contact angle carries more thrust and less speed than a 15° in the same envelope, which suits spindle and screw-drive positions where axial load is substantial. The SUL grind lets any two of these bearings clamp together to light preload, so pairs, triplex and quad stacks can be built from single pieces held in stock.
One bearing, single universally ground, open.
Mounting is onto a clean straight journal against a square shoulder, with the marked face oriented to the thrust direction or to the mating bearing in a stacked arrangement. Precision-class bearings are fitted to measured interference rather than by feel.
Same-spec equivalents at 25° and P4-class precision include the SKF 7007 ACD/P4A and the FAG B7007-E-T-P4S-UL. A 7007 at a 15° or 40° angle, or a duplex-ground pair, is a related size rather than an interchange for a single universal bearing.
