Tapered roller bearing 32315-B transmits combined radial and axial loads through angled raceways acting on a single row of tapered rollers. Bore diameter is 75.0 mm, outside diameter 160.0 mm, net mass 5.636 kg, limiting speed 4350.0 1/min. The bearing follows main dimensions according to DIN 720 and is of separable design, with cone and cup mountable independently. Cage execution is standard. Being separable, the inner and outer assemblies can be fitted and adjusted independently, which allows setting the internal clearance during mounting to suit the application. The single-row tapered configuration handles axial load in one direction combined with radial load, so shaft support typically requires pairing with a second bearing to take up thrust in the opposite direction. No sealing is integrated, so the arrangement relies on external sealing and a separate lubrication supply, either grease or oil, appropriate to the limiting speed stated.
