23030K-C3 Spherical roller bearing C3

The 23030K-C3 is a spherical roller bearing with a 150 mm tapered bore (1:12 taper) and C3 radial internal clearance. The tapered bore design allows for secure mounting directly on tapered shafts or adapter sleeves, while the greater-than-normal C3 clearance accommodates thermal expansion and misalignment in operating conditions.

Spherical roller bearings are self-aligning double-row bearings designed for heavy radial loads and moderate thrust loads in both directions. Common applications include mining equipment, construction machinery, paper mills, gearboxes, and other industrial equipment where shaft deflection or misalignment may occur.
