22318K-C3 Spherical roller bearing C3

22318K-C3 The 22318K-C3 is a spherical roller bearing with a 90mm 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 C3 clearance provides greater operating clearance than standard for applications with thermal expansion or misalignment requirements. Spherical roller bearings are double-row, self-aligning bearings designed to accommodate heavy radial and moderate axial loads while compensating for shaft deflection and misalignment. Common applications include industrial gearboxes, mining equipment, paper mills, crushers, vibrating screens, and heavy-duty conveyor systems where shaft misalignment or deflection is expected.
