23028K-C4 Spherical roller bearing C4

23028K-C4 The 23028K-C4 is a spherical roller bearing with a 140 mm bore diameter, featuring a tapered bore (1:12 taper) and C4 radial internal clearance. The tapered bore design allows secure mounting on tapered shafts or adapter sleeves, while the C4 clearance accommodates thermal expansion and misalignment in operating conditions. Spherical roller bearings are self-aligning and designed to handle heavy radial loads and moderate axial loads in both directions. Common applications include industrial gearboxes, mining equipment, paper mills, construction machinery, and heavy-duty conveyors where shaft deflection or misalignment may occur.
