This spherical roller bearing carries radial loads and accommodates shaft misalignment through its two rows of rollers on a common sphered raceway. Main dimensions follow DIN 635-2, with a bore diameter of 320.0 mm, outside diameter of 540.0 mm, and width of 218.0 mm; net mass is 196.0 kg. The bearing has a tapered bore K30 (taper 1:30), design BE, and runs with C3 internal clearance, giving it a wider operating clearance range than standard to compensate for interference fit on a tapered seat or sleeve. Limiting speed is 1010.0 1/min, reference speed 415.0 1/min. The tapered bore allows mounting directly on a tapered shaft seat or with an adapter or withdrawal sleeve, which simplifies achieving the correct fit and preload without measuring shaft tolerances as closely as with a cylindrical bore. The JPB cage guides the rollers and contributes to stable operation at the given speed ratings. C3 clearance suits applications where thermal expansion or an interference fit would otherwise reduce internal clearance below the working range. Relubrication is standard, meaning the bearing is designed for regular replenishment of grease or oil through its intended lubrication points rather than sealed-for-life operation.
