21312K-C3 Spherical roller bearing C3

21312K-C3 The 21312K-C3 is a spherical roller bearing with a 60mm tapered bore (1:12 taper) and C3 radial clearance, designed to accommodate higher operating temperatures and thermal expansion. The tapered bore enables direct mounting on tapered shafts or mounting with adapter sleeves on cylindrical shafts. Spherical roller bearings are self-aligning and suitable for heavy radial loads and moderate thrust loads in applications with shaft deflection or misalignment. Common applications include industrial gearboxes, mining equipment, paper mill machinery, and material handling systems where robust performance under demanding conditions is required.
