FAG spherical roller bearings are self-aligning, with two rows of rollers and a spherical raceway on the outer ring. They handle radial and axial loads in both directions and tolerate angular misalignment between shaft and housing, making them suitable for equipment where shaft deflection or seat deformation occurs.

The part number breaks down into meaningful blocks. The initial number gives the size. The letter S denotes an annular groove plus three lubrication holes in the outer ring. The K indicates a 1:12 tapered bore. MB identifies a solid brass cage guided by the inner ring. So in 23936-S-K-MB or 23944-S-K-MB, each suffix tells you about mounting or lubrication. If your required combination differs, send it to us on WhatsApp for verification.

These bearings are common in reducers and gearboxes, centrifugal pumps, induced draft fans, vibrating screens, mills, and mining and cement equipment. They also appear in paper machines, cranes and conveyors where the shaft deflects or the housing lacks rigidity. Their self-aligning capability offsets alignment errors and frame distortion, which reduces parasitic forces on the shaft.

Selection depends on load type and expected misalignment, rotation speed and lubrication method. The S groove with holes allows relubrication from the housing. The K tapered bore mounts with an adapter sleeve or withdrawal sleeve, simplifying internal clearance adjustment. The MB solid brass cage suits high loads and moderate speeds. During mounting, check initial alignment, seat cleanliness and residual clearance per the equipment manual.

Spherical roller bearings are dimensionally interchangeable between brands for the same basic designation: bore, outer diameter and width match. However, suffixes are not always equivalent. Grooves, lubrication holes, taper and cage type can vary. Compare the complete designation, not just the size number. To replace a bearing from another brand, send the full part number and we will review the correspondence.

MR Industrial Accessories LLC supplies FAG bearings to customers across the United States and in several Latin American countries. If your equipment uses a spherical roller bearing from this series, send the part number or model via WhatsApp or email. Our team replies promptly, can suggest equivalents and help you choose the right adapter sleeve, lubrication and mounting approach.
