21306-C3 Spherical roller bearing C3

The 21306-C3 is a spherical roller bearing with a 30 mm bore diameter from the 213 series. It features C3 radial internal clearance, which is greater than normal clearance, allowing for thermal expansion and shaft deflection in operating conditions.

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, pumps, and construction machinery where shaft misalignment or deflection may occur.
