A Fafnir 7215WN-SU angular contact ball bearing, 75 mm bore by 130 mm outside diameter by 25 mm wide, single universally ground. Fafnir is Timken’s super-precision line.
The 7215 base number places the bearing in the ISO 72 dimension series, and the 15 size code gives a 75 mm bore. WN is Fafnir’s angular contact family designation, and SU marks the bearing as single universally ground.
An angular contact ball bearing takes radial and one-direction axial load together, and is located axially by whatever it is clamped against. The SU grind is the useful part of this designation: the ring faces are relieved so that two or more of these bearings clamped together come up to a defined preload, which means a pair, a triplex or a quad can be built from single pieces rather than ordering a factory-matched set.
One bearing, single universally ground, open.
An angular contact bearing carries thrust in one direction only, so it is mounted with the marked face oriented to the load, or paired against a second bearing where the load reverses. Mounting is onto a clean straight journal against a square shoulder.
The base number is 7215, so the size envelope matches a 7215-series angular contact bearing from any maker. Contact angle and preload are not coded in this designation, and both have to match for a substitution, so same-envelope 7215 bearings from other brands are related sizes rather than confirmed interchanges.
