This spherical roller bearing carries a 320.0 mm bore diameter, 540.0 mm outside diameter and 218.0 mm width, with a net mass of 199.5 kg. The design is symmetric with rib washer, executed in BE design with Z bore type. Radial internal clearance is in group CN (Group N), and the cage is made in JPB execution. Limiting speed is rated at 1010.0 1/min, while the reference speed is 415.0 1/min, both values relevant for selecting drive parameters within the bearing's mechanical limits. The symmetric roller profile combined with CN clearance allows the bearing to accommodate shaft misalignment while maintaining even load distribution across the double row of rollers. The JPB cage construction supports stable roller guidance under the radial and moderate axial loads typical for this bearing series. Relubrication is standard, meaning the bearing is designed for periodic grease replenishment through its lubrication channels rather than sealed-for-life operation. Dimensionally and constructionally interchangeable references include NTN 24164B, SKF 24164CC/W33, and TIMKEN 24164CAW33.
