The SKF spherical roller bearing is a self-aligning component with two rows of rollers that accommodates radial and axial loads in both directions, even with misaligned shafts. It is used in equipment where shaft deflection or mounting errors are common, such as conveyor belts, mills, pumps and gearboxes. Its self-aligning design simplifies mounting and extends service life under demanding conditions. At MR Accesorios Industriales we supply them and advise you on choosing the correct variant.

The designation of these bearings combines numbers and letters that indicate their geometry and performance. In the 213 series, the first digit indicates the bearing type and the following digits the dimension series; the suffix EW defines the stamped steel cage design, optimized for high speeds and loads. The slash separates the basic code from additional variants, such as C3, which establishes a larger internal radial clearance than standard. For example, 21308 EW/C3 identifies a spherical roller bearing with steel cage and C3 clearance. Knowing these suffixes is key to ordering the exact replacement.

In Argentine industry, these bearings are found in mining, cement, steel, paper and aggregate processing equipment. They appear in belt conveyors, vibrating screens, ball and hammer mills, high-flow centrifugal pumps and speed reducers. They are also used in agricultural machinery and food plants, where cleanliness and resistance to contamination are important. Their ability to withstand misalignment makes them ideal for long shafts or shafts mounted in structures that deflect under load.

To select correctly, take into account radial and axial load, rotational speed and environmental conditions. Sealing is critical: in dusty or humid environments, choose variants with seals or flingers. The C3 internal clearance is recommended when there are interference fits or thermal gradients. Lubrication must be adequate: high-quality grease for high temperatures or oil in circulation systems. During mounting, verify alignment and use controlled impact tools to avoid damaging the rollers. Poor practice shortens bearing life.

SKF spherical roller bearings are interchangeable with those from other European, Japanese or American brands that follow the same standardized dimensions. When replacing, compare not only the basic code but also the suffixes: cage, internal clearance and heat treatment can vary between manufacturers. If space allows, a bronze cage can be an alternative to the stamped steel one. Always verify the complete code of the original bearing and consult our technical team with any questions.
