- /850Bore
- 850 mm bore.
- XL-MSuffix
- FAG suffix: it defines the variant (sealing, cage, internal clearance or other features).
C 39/850 is the standard (ISO) basic designation: it defines the type, the series and the bore.

Toroidal roller bearings are high-capacity radial bearings designed to withstand heavy loads and compensate for misalignment. Their roller and raceway geometry ensures stable operation in demanding applications. At MR Accesorios Industriales we sell the FAG line with designations such as C30/500-XL-M or C31/530-XL-M. If you need to identify the correct code for your equipment, write to us on WhatsApp and we will advise you.
The designation of this series combines the letter C with a number indicating the dimension series and a suffix identifying execution variants. For example, in C30/500-XL-M, the C corresponds to the toroidal roller family, 30 is the dimension series, 500 the bore diameter in millimeters, XL the longer-life execution and M the brass cage. In C31/530-XL-M, the 31 indicates a series with higher load capacity. Knowing these components lets you read the full code and order the exact replacement.
These bearings are used in equipment with significant radial loads and shafts that may flex, such as gearboxes, paper machines, cranes, mills and industrial drives. In the Argentine market, FAG toroidal roller bearings appear in mining, steel, cement and materials handling applications, where robustness and the ability to compensate for misalignment are critical to avoid unplanned downtime.
To select the right bearing, take into account the radial and axial load, rotation speed, type of lubrication and required sealing. The C30 series is usually used in arrangements with predominantly radial load, while the C31 series offers higher capacity. Installation requires careful alignment and proper lubrication; the M brass cage provides resistance under severe conditions. Always check the internal clearance and the fit on the shaft and in the housing.
FAG toroidal roller bearings can be interchanged with equivalent products from other brands that follow the same dimensional designation, but tolerances and capacities may vary. Therefore, when requesting a quote, it is important to provide the full code and the operating conditions. At MR Accesorios Industriales we can guide you on interchangeability.

Frequently Asked Questions
- What are the dimensions of the FAG C39/850-XL-M bearing?
- The FAG C39/850-XL-M bearing has a 850 mm bore, a 1120 mm outside diameter and a 200 mm width (850 x 1120 x 200 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation C 39/850.
- What does the XL-M suffix mean on a FAG bearing?
- XL indicates a longer-life execution, with improvements in design and materials. M indicates that the cage is made of brass, which provides strength and stability in applications with high loads or high speeds.
- How do I choose between the C30 series and the C31 series?
- The C31 series has a higher load capacity than the C30. The choice depends on the radial load the bearing must withstand and the available space. If you have doubts, write to us on WhatsApp with your equipment data and we will advise you.
- Are FAG toroidal roller bearings interchangeable with other brands?
- They can be interchanged with bearings of similar dimensions from other brands, but tolerances and capacities may differ. Always check the full code and contact us on WhatsApp to confirm the equivalence before buying.
