22212K-C3 is a spherical roller bearing, 60 mm bore × 110 mm OD × 28 mm wide (2.3622 × 4.3307 × 1.1024 in). It has C3 internal clearance and a tapered bore (1:12).
The 22212K-C3 is a spherical roller bearing with a 60mm tapered bore (1:12 taper) and C3 radial internal clearance. The tapered bore design allows for secure mounting on tapered shafts or adapter sleeves, while the C3 clearance accommodates thermal expansion and shaft deflection in operating conditions.
