This spherical roller bearing carries radial loads together with oscillating loads acting from either direction, compensating shaft misalignment thanks to its two rows of rollers on a common sphered raceway. It has a bore diameter of 170.0 mm, outside diameter of 360.0 mm, width of 120.0 mm and a net mass of 57.56 kg. The limiting speed is 2130.0 1/min, with a reference speed of 1320.0 1/min. The bore is tapered, coded K, allowing mounting on an adapter sleeve or directly on a tapered shaft seat with restricted diameter tolerances. The bearing is produced with C4 internal clearance, which offsets the reduction of internal clearance occurring during mounting on a tapered seat and during operation under thermal expansion. The polyamide cage, designation JPA, guides the rollers with reduced friction and supports operation at the given speed ratings. Design BE reflects the internal geometry of the bearing. With no integrated seals, relubrication follows the standard feature, so lubricant supply and maintenance intervals must be planned according to operating conditions and the tapered bore mounting method.
