21320K-C3 Spherical roller bearing C3

21320K-C3 The 21320K-C3 is a spherical roller bearing with a 100 mm 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 accommodates thermal expansion and shaft deflection in demanding applications. Spherical roller bearings are self-aligning and excel in heavy radial and moderate thrust load applications where shaft misalignment or deflection is present. Common applications include mining equipment, paper mills, gearboxes, crushers, and industrial fans where robust performance under challenging conditions is required.
