Description

SKF 22218 EK/C3W64 is a spherical roller bearing reference, within Bearings. Request a quote for 22218 EK/C3W64 via WhatsApp or email with the quantity you need; we respond promptly with lead time and equivalents.

The SKF spherical roller bearing is a two-row oscillating component designed to withstand high radial loads and axial loads in both directions. Its spherical outer raceway allows the shaft to misalign without losing functionality, which simplifies mounting and absorbs alignment errors. It is used in equipment subject to vibration, deflection or assemblies where frame rigidity makes perfect alignment difficult. MR Accesorios Industriales supplies this line with technical advice so you can choose the right variant for your application.

The designation of this series combines letters and numbers that indicate key characteristics. The suffix EK indicates a tapered bore with 1:12 taper, intended for mounting on an adapter sleeve or tapered shaft. The letter C followed by a number defines the internal clearance, for example C3 for greater than standard clearance. The suffix W with a number, such as W64, identifies a special manufacturer modification, generally linked to particular tolerances or treatments. The example 22218 EK/C3W64 combines these variants: 222 series, tapered bore, C3 clearance and W64 modification.

In Argentine industry, these bearings appear in mining, cement, steel, paper and aggregate processing equipment. They are found in vibrating screens, mills, crushers, induced draft fans and high-load conveyors. They are also present in agricultural machinery and in balanced feed plants, where dust and vibration demand robust bearings. Their self-aligning capability makes them suitable for long shafts that deflect under load, or for welded frames where achieving perfect alignment between supports is costly.

To select correctly, take into account radial and axial load, rotational speed and environmental conditions. If mounting is on a tapered shaft, verify the recommended axial drive-up to obtain the desired internal clearance. In contaminated applications, choose suitable seals or protection plates. Lubrication must be compatible with temperature and speed: high-viscosity grease for high loads and low speeds, or oil in circulating systems. Initial alignment and controlled tightening of the adapter sleeves prevent premature failures.

Spherical roller bearings from different brands are interchangeable if main dimensions, bore type and internal clearance match. Suffix designations may vary between manufacturers, so it is advisable to verify functional equivalence before replacing. In general, a code with tapered bore and C3 clearance from one brand can be replaced by another with a similar configuration, but always check tolerances and the type of special modification. MR Accesorios Industriales can help you interpret the differences between nomenclatures.

Frequently Asked Questions

What does the EK suffix mean in a spherical roller bearing?
The EK suffix indicates that the bearing has a tapered bore with 1:12 taper. This allows it to be mounted on a tapered shaft or on an adapter sleeve, which facilitates adjustment of internal clearance and dismounting. It is a common option when a firm and adjustable fit is sought.
How do I choose the right internal clearance for my application?
Internal clearance depends on load, speed and working temperature. Greater clearance, such as C3, compensates for thermal expansion and heavy loads. If mounting is on a tapered shaft, final clearance is adjusted during mounting. Consult us with your equipment data to determine the most suitable one.
Can I replace an SKF bearing with another brand?
Yes, if main dimensions, bore type and internal clearance match. Suffix designations may change between manufacturers, so functional equivalence must be verified. Send the original code and we will help you find the right alternative.
