21313K-C3 Spherical roller bearing C3

21313K-C3 The 21313K-C3 is a spherical roller bearing with a 65mm tapered bore (1:12 taper) and C3 radial internal clearance. The tapered bore design allows for secure mounting directly on tapered shafts or adapter sleeves, while the C3 clearance provides greater internal space than standard to accommodate thermal expansion or shaft deflection. Spherical roller bearings are self-aligning, double-row bearings designed to handle heavy radial loads and moderate axial loads in both directions. They are commonly used in mining equipment, construction machinery, paper mills, gearboxes, and other industrial applications where shaft misalignment or deflection is expected.
