Decoding FAG 23936-S-MB
- 239Series
- Spherical roller bearings, 239 series. Series differ in outside diameter and width even when the bore is the same.
- 36Bore
- Bore 180 mm (36 × 5).
- S-MBSuffix
- FAG suffix: identifies the variant, such as seals or shields, cage, internal clearance or other features.
23936 is the standard ISO basic designation, which sets the bearing type, series and bore.
Description
FAG 23936-S-MB measures 180 mm across the bore and 250 mm across the outside diameter; its width is 52 mm (180 x 250 x 52 mm).

The FAG 23936-S-MB, 23938-S-MB and 23940-S-MB are double-row self-aligning spherical roller bearings. They carry heavy radial loads together with axial loads in either direction, and they tolerate shaft deflection and seat inaccuracies that would trouble a rigid bearing. MR Industrial Accessories LLC supplies this line to maintenance and purchasing teams throughout the United States and in several Latin American countries, and helps pinpoint the right code for each application.
Reading the code is the fastest way to know what you are ordering. The leading digits set the size and dimension series, so 23936, 23938 and 23940 differ only in size. The S suffix marks an outer ring with a lubrication groove and holes. The MB suffix identifies a solid brass cage guided by the inner ring. Same construction, three sizes.
These bearings suit mining, cement, steel, paper and aggregate processing equipment, as well as gearboxes, conveyors, mills, screens and other continuous-duty machines. Where loads run high and alignment is never perfect, the self-aligning behavior pays off on long or flexing shafts and on housings whose seating face is not truly square.
Selection comes down to radial load, axial load, speed and shaft diameter. The S feature makes relubrication in service practical, which matters in dusty or damp areas where grease breaks down. The MB brass cage holds up under demanding duty. At installation, check alignment first, use the correct tools, and pick a lubricant matched to the temperature and speed of the application.
Equivalent designations exist across several brands. Interchangeability can be assessed, but tolerances, internal clearance and cage style deserve a check before substituting. Main dimensions alone do not tell the whole story; the suffix and internal execution decide how the bearing behaves on the job. If you are replacing an existing unit, ask about equivalent options.

Frequently asked questions
- FAG 23936-S-MB bearing: what are its dimensions?
- FAG 23936-S-MB measures 180 mm across the bore and 250 mm across the outside diameter; its width is 52 mm (180 x 250 x 52 mm). Those are the boundary dimensions standardized in ISO 15 for basic designation 23936.
- What does the S suffix indicate on these bearings?
- It means the outer ring carries a lubrication groove and holes, so the bearing can be regreased while it is in service. That helps in applications with heavy load or contaminated surroundings, where the lubricant loses effectiveness over time.
- Why choose the MB cage version?
- MB is a solid brass cage guided by the inner ring. It is specified for severe duty, high speeds or heavy loads, since it is stronger and more stable than a sheet metal cage, and it holds up well in continuous operation.
- How do I get a quote for a spherical roller bearing?
- Send the full code, such as 23936-S-MB, through WhatsApp or email, or provide the shaft dimensions and equipment model. The team replies promptly and can point you to the right option for your application.
