21311K-C3
The 21311K-C3 is a spherical roller bearing with a 55 mm tapered bore (1:12 taper) and C3 radial internal clearance. The tapered bore design allows secure mounting directly onto tapered shafts or standard cylindrical shafts using adapter sleeves or withdrawal sleeves.
Spherical roller bearings are self-aligning and designed to accommodate heavy radial loads and moderate axial loads in both directions. Common applications include industrial gearboxes, mining equipment, paper mills, crushers, vibrating screens, and conveyor systems where shaft deflection or misalignment may occur.
