21315K-C3 Spherical roller bearing C3

The 21315K-C3 is a spherical roller bearing with a 75mm tapered bore (1:12 taper) and C3 radial internal clearance. The tapered bore design allows for secure mounting directly onto tapered shafts or adapter sleeves, while the C3 clearance provides greater internal clearance than standard for applications with thermal expansion or shaft deflection.

Spherical roller bearings are self-aligning and accommodate misalignment between shaft and housing. They are well-suited for heavy radial and moderate axial loads in industrial equipment including gearboxes, conveyor systems, construction machinery, and mining equipment where shaft deflection or misalignment is present.
