SKF spherical roller bearings of the 223 series with EKJA/VA405 suffixes are self-aligning bearings with two rows of rollers, designed to withstand high radial loads and angular misalignment. Their robust construction and special treatment make them suitable for applications with vibration and shock, such as vibrating screens and crushing equipment. MR Accesorios Industriales supplies this line, with technical advice to select the correct size for your equipment.

The designation 22315 EKJA/VA405 is interpreted as follows: the prefix 223 indicates that it is a spherical roller bearing of the 223 series, with a wide section and high load capacity. The letter E indicates an internally optimized design. The K means it has a tapered bore (taper 1:12), which allows it to be mounted with an adapter sleeve or directly on a tapered shaft. The J refers to the stamped steel sheet cage. The final A indicates a special execution. The suffix /VA405 corresponds to a variant with special heat treatment for vibrating applications, with greater dimensional stability and shock tolerance. Examples in the series are 22315, 22318 and 22320, all with the same EKJA/VA405 suffix.

These bearings are used in industries where there are heavy loads and oscillating movements. In Argentina they are common in vibrating screens in mining and quarries, in screens in the grain industry, in jaw and cone crushers, in earthmoving equipment and in road machinery. They also appear in large industrial fans, in process centrifugal pumps and in gearboxes subject to vibration. The self-aligning capability compensates for small shaft deflections or mounting misalignments, which reduces maintenance on critical equipment.

To select the correct bearing, take into account the radial and axial load it must withstand, the rotation speed and the type of fit. If the shaft is tapered, the K series is mounted with an adapter sleeve; if it is cylindrical, the version without K is required. The sealing is open in this execution, so it requires adequate lubrication and protection against contaminants. Lubrication can be grease or oil, depending on the operating conditions. During mounting, check the initial alignment and internal clearance; excessive or insufficient clearance shortens service life. For vibrating applications, the VA405 suffix offers greater resistance.

As for equivalents, spherical roller bearings of equivalent series are available from different brands, but the suffixes and internal treatments are not always interchangeable. A bearing with a similar designation may differ in cage, clearance or heat treatment. Therefore, when replacing, do not rely only on the bore, outside diameter and width dimensions: also check the bore type, the cage and the execution suffix. If you have doubts, ask us with the complete code engraved on the bearing and we will help you identify the correct version.
