How to read FAG 238/630-XL-MA1
- 238Series
- Spherical roller bearings, 238 series. For the same bore, each series has a different outside diameter and width.
- /630Bore
- 630 mm bore.
- XL-MA1Suffix
- FAG suffix: it defines the variant (sealing, cage, internal clearance or other features).
238/630 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description
The FAG 238/630-XL-MA1 bearing has a 630 mm bore, a 780 mm outside diameter and a 112 mm width (630 x 780 x 112 mm).

The spherical roller bearing is a component designed to withstand high radial loads and axial loads in both directions, even when the shaft presents angular misalignment. Its double row of spherical rollers and its spherical outer raceway allow it to self-align, which reduces stress on the housing and extends the service life of the assembly. It is used in applications where mounting rigidity is not perfect, such as heavy transmissions, mills or mining and cement equipment.
The designation of this series combines a size number with suffixes that indicate construction features. In the example 238/630-XL-MA1, the numeric prefix defines the dimension series; the suffix XL identifies the X-life execution, with optimized raceways and higher load capacity; MA1 indicates the machined brass cage, guided by the outer ring. Knowing these suffixes is key to ordering the correct replacement.
In Argentine industry, these bearings appear in crushing, grinding, rotary kiln, conveyor belt and paper machine equipment, where loads are high and shafts may bend. They are also found in large gearboxes and in steel industry applications. Their self-aligning capability makes them suitable for mountings where perfect alignment between housings cannot be guaranteed.
To select the right bearing, take into account the radial and axial load, the rotation speed and the type of lubrication. The machined brass cage is suitable for high demands and elevated temperatures. During mounting, verify the initial alignment and avoid striking the rings; correct lubrication and effective sealing against contaminants make the difference in service life.
When looking for equivalents with other brands, do not rely only on diameter and width: the execution and cage suffixes may vary. The safest approach is to compare the complete designation and consult the tolerances and internal clearance. At MR Accesorios Industriales we can guide you so that the replacement meets your equipment's requirements.

Frequently Asked Questions
- What are the dimensions of the FAG 238/630-XL-MA1 bearing?
- The FAG 238/630-XL-MA1 bearing has a 630 mm bore, a 780 mm outside diameter and a 112 mm width (630 x 780 x 112 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 238/630.
- What does the XL suffix mean in the designation?
- XL corresponds to the FAG X-life execution, which incorporates improvements in the design of the raceways and rollers to increase load capacity and service life. It is important to respect this suffix when ordering a replacement, because not all bearings of the same series include it.
- How do I know if this bearing is the right one for my equipment?
- Verify the complete designation engraved on the bearing or in the equipment manual. The numbers and suffixes indicate dimensions, cage and execution. If you have doubts, send us the part number by WhatsApp and we will help you confirm the equivalent with the available technical information.
- What care does the mounting of a self-aligning bearing require?
- It is essential to clean the housing and the shaft, verify alignment and apply the mounting force on the corresponding ring, never through the rollers. Adequate lubrication and sealing against dust and moisture extend the bearing's service life.
