21320K-C3 is a spherical roller bearing, 100 mm bore × 215 mm OD × 47 mm wide (3.937 × 8.4646 × 1.8504 in). It has C3 internal clearance and a tapered bore (1:12).

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.
