For equipment that must tolerate shaft misalignment while carrying combined radial and axial loads, the SKF 22218 EK/C3W64 spherical roller bearing is a practical choice. Its two rows of rollers run on a spherical outer raceway, so the shaft can deflect without compromising operation. This makes mounting simpler and helps absorb alignment errors in driven machinery.

The code 22218 EK/C3W64 tells you what you are getting. The 22218 is the basic bearing size and series. EK means a tapered bore with a 1:12 taper, so it mounts on a tapered shaft or an adapter sleeve. C3 indicates internal clearance greater than standard. W64 is a manufacturer-specific modification, often tied to tolerances or surface treatments. When you read a designation like this, break it into these blocks to confirm the fit, clearance and any special features.

These bearings are common in mining, cement, steel, paper and aggregate processing. You will find them in vibrating screens, mills, crushers, induced draft fans and high-load conveyors. Agricultural machinery and balanced feed plants also use them, where dust and vibration are constant. The self-aligning design suits long shafts that bend under load or welded frames where perfect alignment between supports is hard to achieve.

Selection starts with radial and axial load, speed and the environment. If you mount on a tapered shaft, check the recommended axial drive-up to get the internal clearance you need. In dirty conditions, add suitable seals or protection plates. Match lubrication to temperature and speed—high-viscosity grease for heavy loads and low speeds, or oil in circulating systems. Proper initial alignment and controlled tightening of adapter sleeves help avoid early failures.

Bearings from different brands can be swapped if the main dimensions, bore type and internal clearance match. Suffix designations may differ between manufacturers, so verify functional equivalence before replacing. A code with a tapered bore and C3 clearance from one brand often has a counterpart with a similar configuration, but always check tolerances and the type of special modification. MR Industrial Accessories can help you interpret the differences between nomenclatures.
