A Timken 275158 tapered roller bearing cup — the outer race of a large-bore inch tapered roller bearing, supplied to Timken precision Class 3. Outside diameter 15-7/8 in, width 1-13/16 in.
275158 is a Timken inch tapered roller cup number. The trailing -3, marked on the carton as *3, is the Timken precision class: Class 3 holds tighter bore, outside-diameter and running-accuracy tolerances than standard Class 4 or K.
Class 3 tightens the cup outside-diameter and raceway runout, which reduces the eccentricity carried into the housing and lets the assembly hold a repeatable endplay setting. That accuracy is what large mill and gear-drive positions specify it for.

Cup only. Sold as 1 Pc.
The cup presses into the housing bore against a square machined shoulder; the housing bore roundness governs whether the Class 3 raceway accuracy survives installation.
A 275158 cup in standard class is the same envelope at wider tolerance, which makes it a related size rather than an equivalent where Class 3 accuracy is specified.
