How to read FAG 238/710-MB
- 238Series
- Spherical roller bearings, 238 series. For the same bore, each series has a different outside diameter and width.
- /710Bore
- 710 mm bore.
- MBSuffix
- FAG suffix: it defines the variant (sealing, cage, internal clearance or other features).
238/710 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description
The FAG 238/710-MB bearing has a 710 mm bore, a 870 mm outside diameter and a 118 mm width (710 x 870 x 118 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. Their self-aligning design makes them suitable for applications where shaft deflection or mounting errors are unavoidable. MR Accesorios Industriales sells this line with the technical assistance backed by the industry.
The designation of these bearings combines a series number with the suffix -MB. In the examples, series 238, 239 and 230 correspond to thin-section, medium and higher load capacity designs, respectively, within this family. The suffix -MB indicates a machined brass cage, roller-guided, which provides robustness and heat dissipation in continuous service. The numbers after the slash include the bore diameter, which is expressed in millimeters when it exceeds 500 mm, or in a two-digit code for smaller diameters. Thus, a 239/500-MB has a 500 mm bore.
These bearings are used in heavy equipment in mining, cement, steel, paper and energy, where loads are high and alignment conditions are difficult. In Argentina, they are commonly found in large gearboxes, mills, rotary kilns, conveyor belts and continuous process machines. Their self-aligning capability compensates for shaft deflection and mounting errors, which extends the service life of the assembly and reduces downtime for corrective maintenance.
To select the right bearing, take into account the radial and axial load, the rotation speed and the type of lubrication. The -MB cage is suitable for high temperatures and severe loads, but requires a lubricant that withstands those conditions. During mounting, check the initial alignment and internal clearance; excessive adjustment can cause overheating. Lubrication can be grease or oil, depending on the operating regime, and the sealing must be chosen according to the environment: dust, moisture or contaminants require additional protection.
When replacing a spherical roller bearing, it is common to find equivalents between different brands that meet the same standardized dimensions. However, not all suffixes are interchangeable: the cage, heat treatment and internal clearance may vary. Therefore, it is always advisable to verify the full part number and the service conditions before substituting. MR Accesorios Industriales can advise you on compatibility.

Frequently Asked Questions
- What are the dimensions of the FAG 238/710-MB bearing?
- The FAG 238/710-MB bearing has a 710 mm bore, a 870 mm outside diameter and a 118 mm width (710 x 870 x 118 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 238/710.
- What does the -MB suffix mean on an FAG bearing?
- The -MB suffix indicates that the bearing has a machined brass cage, roller-guided. This cage is robust and suitable for high loads and temperatures, and helps dissipate the heat generated in continuous service.
- How do I read the part number of a bearing such as 239/500-MB?
- The number 239 identifies the medium-section spherical roller series. The number after the slash, 500, indicates the bore diameter in millimeters. The -MB suffix indicates the cage type. Thus, 239/500-MB is a bearing with a 500 mm bore.
- What applications do spherical roller bearings have in Argentina?
- They are used in heavy equipment such as mills, rotary kilns, gearboxes, conveyor belts and machinery in mining, cement, steel and paper. Their self-aligning capability makes them ideal for shafts with deflection or difficult mountings.
