The Timken 15578/15520 is a single-row tapered roller bearing designed to accommodate combined radial and axial loads. Its tapered rollers and raceways provide support for bearing arrangements in industrial machinery and other equipment.
The bearing consists of an 15578 cone, which includes the inner ring, rollers and cage, and an 15520 cup, which forms the outer ring. The separable design allows the cone and cup to be installed individually.
This bearing has a 25.400 mm bore, a 57.150 mm outside diameter and an overall assembled width of 17.462 mm. It accommodates axial load in one direction and can be used with an opposing bearing where axial location in both directions is required.
