Spherical roller bearings are self-aligning bearings with two rows of rollers, a spherical raceway on the outer ring and a cylindrical or tapered bore on the inner ring. They absorb radial and axial loads in both directions and tolerate angular misalignment between shaft and housing. They are used in equipment with shaft deflection, mountings that are difficult to align or seats that deform under load, such as transmissions, pumps, fans and process machinery. MR Accesorios Industriales supplies the FAG brand in Buenos Aires, Argentina.

The designation of this series is read in blocks: the initial number indicates the size, the letter S indicates an annular groove and three lubrication holes in the outer ring, the K indicates a tapered bore (1:12 taper), and MB identifies the solid brass cage guided by the inner ring. Thus, in 23936-S-K-MB or 23944-S-K-MB each block contributes a mounting or lubrication feature. If the part number you're looking for has another combination of suffixes, write to us on WhatsApp and we'll verify it.

In Argentine industry these bearings appear in reducers and gearboxes, centrifugal pumps, induced draft fans, vibrating screens, mills and mining and cement equipment. They are also chosen in paper machines, cranes and conveyors where the shaft deflects or the housing is not rigid. Their ability to self-align compensates for alignment errors and frame deformations, which reduces parasitic forces on the shaft and extends the life of the assembly.

To select correctly, take into account the type of load and the expected misalignment, the rotation speed and the lubrication method. The S groove with holes allows relubrication from the housing; the K tapered bore is mounted with an adapter sleeve or withdrawal sleeve, which makes adjusting the internal clearance easier. The MB solid brass cage is suitable for high loads and moderate speeds. During mounting, verify the initial alignment, the cleanliness of the seat and the residual clearance according to the equipment manual.

Between brands, spherical roller bearings are interchangeable by standardized dimensions: bore, outer diameter and width match between manufacturers for the same basic designation. The suffixes, however, are not always equivalent: grooves, lubrication holes, taper and cage type may vary. That is why it is advisable to compare the complete designation and not just the size number. If you need to replace a bearing from another brand, send us the complete part number and we'll review the correspondence.
