This spherical roller bearing has a bore diameter of 150.0 mm, an outside diameter of 225.0 mm, and a width of 75.0 mm, which fix the shaft and housing seating dimensions. Net mass is 10.334 kg. The limiting speed is 2750.0 1/min and the reference speed is 1790.0 1/min, setting the speed boundaries for continuous operation. Design BE with symmetric rollers and a rib washer, bore type Z, and cage JPB define the internal geometry and the rolling element guidance. Radial internal clearance is CN (Group N), the standard clearance class, suitable for normal mounting conditions without induced preload. The symmetric roller profile allows the bearing to accommodate shaft misalignment and some axial displacement within the clearance range. Relubrication is standard, meaning the bearing is designed for periodic grease replenishment during service. Dimensionally and constructionally equivalent designations are KOYO 24030RH, NSK 24030CE4, NSK 24030CE4S11, NTN 24030C, NTN 24030CD1, RHP 24030EJW33, RHP 24030JW33, SKF 24030CC/W33, SNR 24030EAW33, TORRINGTON 24030SD.
