This spherical roller bearing has two rows of rollers set on a spherical outer raceway, allowing the inner ring to self-align relative to the outer ring. The bore diameter is 120.0 mm, outside diameter 180.0 mm, and width 46.0 mm, with a tapered bore (taper 1:12, bore type K) for mounting on an adapter sleeve or tapered shaft seat. Net mass is 3.906 kg. Limiting speed is rated at 3950 1/min, with a reference speed of 2800 1/min. The cage is of type M, machined brass, running at design E1A. Radial internal clearance is CN (Group N), the standard clearance class, suited for normal fit and operating temperature conditions. The tapered bore simplifies mounting and allows clearance adjustment during installation by driving the bearing up the tapered seat. Relubrication is standard, meaning the bearing is designed for periodic grease replenishment through its lubrication path. The self-aligning design accommodates shaft misalignment and deflection without introducing additional edge loading on the rollers. Dimensionally and constructionally, this bearing corresponds to GPZ 3113124, LINK-BELT 23024LBK, NSK 23024CDKE4, NTN 23024BK, NTN 23024BKD1, NTN 23024K, RHP 23024EKJW33, SKF 23024CCK/W33, SKF 23024CK.
