Two rows of barrel rollers running between a common outer raceway and two inner raceways allow this spherical roller bearing to accommodate misalignment and radial loads while compensating for shaft deflection or housing bore inaccuracy. Main dimensions follow DIN 635-2: 75.0 mm bore, 160.0 mm outside diameter, 55.0 mm width, net mass 5.144 kg. The 1:12 tapered bore (K) permits mounting on a tapered shaft seat or with a sleeve, with the E1 design providing an optimized internal geometry and load distribution. Limiting speed is rated at 4500 1/min, reference speed at 3550 1/min. The C3 radial internal clearance, wider than normal, offsets the fit-related clearance reduction that occurs when the tapered bore is drawn up onto the shaft, and also accommodates thermal expansion during operation. The JPA cage guides the rollers and separates the rows, supporting steady operation at the stated speeds. As an open bearing without integrated sealing, it requires external sealing and a separate lubrication arrangement suited to the operating conditions; relubrication is standard, in line with regular maintenance intervals.
