Timken Tapered Bearing Cup, 4.331X0.741

The Timken 394A Tapered Bearing Cup is a precision outer race (cup) used with matching tapered roller bearing components in Timken’s 395 series. Built to handle heavy radial and thrust loads in demanding equipment, it’s the critical “seat” your bearing rollers ride in—so everything spins smoothly instead of sounding like a coffee can full of bolts.
