21307-C3 Spherical roller bearing C3

The 21307-C3 is a spherical roller bearing with a 35 mm bore diameter from the 213 series. It features C3 radial internal clearance, which is greater than normal clearance to accommodate thermal expansion or shaft deflection in operating conditions.

Spherical roller bearings are self-aligning and designed to handle heavy radial loads and moderate axial loads simultaneously. Common applications include industrial gearboxes, mining equipment, paper mills, and construction machinery where shaft misalignment or deflection may occur.
