A Timken 275158-3 tapered roller bearing cup: the outer race of a tapered roller bearing, 15-7/8 in outside diameter by 1-13/16 in wide. Cup only. A cup carries no rollers of its own and runs against a matching cone, which is a separate part number.
The trailing *3, also written -3 or #3, is Timken precision Class 3: a tighter outside diameter and running accuracy grade than standard tolerance.
Class 3 on a cup controls the outside diameter and the raceway runout, which is what holds a large shaft in position rather than merely supporting it. At a 15-7/8 in outside diameter the housing bore tolerance becomes the limiting factor on that accuracy, so the precision grade is only realised in a housing machined to match.
One cup, single row.
The cup is fitted into the housing bore and seated square against its shoulder, pressed on the cup face rather than the raceway. Running clearance or preload is set against the mating cone on assembly.
A 275158 cup at standard tolerance rather than Class 3 is a related size, since the precision grade is the substance of this part number. Cup and cone raceway angles are matched between the two halves of a given Timken pairing.
