SKF Spherical Roller Bearing: 21311, 55 mm Bore, Cylindrical, 120 mm OD

The SKF 21311 E/C3 is a high-clearance spherical roller bearing designed for heavy radial and moderate axial loads in industrial machinery such as conveyors, fans, and gearboxes. Its C3 internal clearance accommodates thermal expansion and misalignment, making it suitable for applications where shaft deflection or housing distortion occurs.

The SKF 21311 E/C3 has a 55 mm bore, 120 mm outer diameter, and 29 mm overall width. It features a cylindrical bore type and is classified under bearing industry number 21311. The C3 clearance provides additional internal radial play for high-temperature or high-speed operations.
