How to read FAG 23936-S-MB

239Series
Spherical roller bearings, 239 series. For the same bore, each series has a different outside diameter and width.
36Bore
180 mm bore: 36 × 5.
S-MBSuffix
FAG suffix: it defines the variant (sealing, cage, internal clearance or other features).

23936 is the standard (ISO) basic designation: it defines the type, the series and the bore.

Description

The FAG 23936-S-MB bearing has a 180 mm bore, a 250 mm outside diameter and a 52 mm width (180 x 250 x 52 mm).

FAG spherical roller bearings are self-aligning double-row components designed to support high radial loads and axial loads in both directions, even with misaligned shafts. They are used in equipment where shaft deflection or mounting errors require self-aligning capability. MR Accesorios Industriales supplies this line in Buenos Aires, Argentina, and helps you identify the exact code for your application.

The designation of this series is read in blocks: the initial number indicates the size and dimension series; the suffix S indicates a design with a lubrication groove and holes in the outer ring; MB identifies the solid brass cage, guided by the inner ring. For example, in 23936-S-MB, 23938-S-MB and 23940-S-MB the size changes, but the configuration with lubrication and brass cage remains. These codes allow you to order the bearing with the same construction features.

In Argentine industry, these bearings appear in mining, cement, steel, paper and aggregate processing equipment. They are also found in gearboxes, conveyor belts, mills, screens and continuous process machines, where loads are high and perfect alignment is not always possible. Their self-aligning capability makes them suitable for long or flexed shafts, and for mountings where the seat is not perfectly perpendicular.

To select the correct bearing, take into account the radial and axial load, the rotation speed and the shaft diameter. The S suffix with lubrication holes facilitates relubrication in service, especially in dusty or humid environments. The MB solid brass cage is suitable for demanding conditions. During installation, verify the initial alignment, use suitable tools and choose a lubricant compatible with the operating temperature and speed.

Spherical roller bearings are available from different brands under equivalent designations. Dimensional and functional interchangeability can be evaluated, but it is always advisable to verify tolerances, internal clearance and cage type. Matching the main dimensions is not enough: the suffix and internal execution define the behavior in service. Ask us about equivalent alternatives if you need to replace an existing bearing.

If you already have the bearing code you need, send it by WhatsApp to MR Accesorios Industriales and we will quote you shortly. If you cannot find it, write to us with the equipment model or shaft dimensions and we will help you identify it. We work with leading brands and advise you so that the replacement is the correct one.

Frequently Asked Questions

What are the dimensions of the FAG 23936-S-MB bearing?
The FAG 23936-S-MB bearing has a 180 mm bore, a 250 mm outside diameter and a 52 mm width (180 x 250 x 52 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 23936.
What does the S suffix mean in a FAG bearing?
The S suffix indicates that the outer ring has a lubrication groove and holes. This allows the bearing to be relubricated during operation, which is useful in applications with high load or contaminated environments where the lubricant degrades over time.
What advantage does the MB cage have?
The MB cage is made of solid brass and is guided by the inner ring. It is chosen for severe working conditions, high speeds or high loads, because it offers greater strength and stability than a sheet metal cage. It is a robust configuration for continuous service.
