21311-C3 Spherical roller bearing C3

21311-C3 The 21311-C3 is a spherical roller bearing with a 55 mm bore diameter from the 213 series. It features C3 radial internal clearance, providing greater clearance than standard to accommodate thermal expansion and shaft deflection in operating conditions. Spherical roller bearings are self-aligning designs capable of accommodating misalignment and shaft deflection while supporting heavy radial and moderate axial loads. Common applications include industrial gearboxes, mining equipment, paper mills, and heavy machinery where robust load capacity and alignment compensation are required.
