21312-C3 Spherical roller bearing C3

21312-C3 The 21312-C3 is a spherical roller bearing with a 60 mm bore diameter from the 213 series, featuring C3 radial internal clearance for applications requiring greater clearance than normal. Spherical roller bearings use barrel-shaped rollers running on a common spherical outer ring raceway, providing self-aligning capability to accommodate shaft deflection and misalignment. Typical applications include industrial gearboxes, mining equipment, paper mills, vibrating machinery, and heavy-duty conveyors where shaft misalignment or deflection is present. The C3 clearance makes this bearing suitable for applications with thermal expansion, interference fits, or operating conditions that reduce internal clearance.
