21308K-C3 Spherical roller bearing C3

The 21308K-C3 is a spherical roller bearing with a 40mm tapered bore (1:12 taper) from the 213 series. It features C3 radial internal clearance, providing greater clearance than standard for applications with thermal expansion or shaft deflection requirements.

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, and heavy machinery where shaft misalignment or deflection is present.
