SKF special bearings of the BT… B line are components designed for applications where the geometry, housing or function differs from a standard bearing. They are used when the available space, type of load or movement to be transmitted requires a custom solution. MR Accesorios Industriales supplies this line, with technical advice to identify the correct reference.
The designation of these bearings combines a base code BT with a series number and the suffix B. In the examples BT1-0507 B and BT1-0509 B, the BT prefix identifies the special bearing category, the numeric block distinguishes each size or variant within the series, and the final letter indicates a particular construction characteristic defined by the manufacturer. Since not all variants share the same interpretation, it is advisable to validate each code against the drawing or the sample before replacing it.
These bearings appear in equipment where a conventional bearing does not fit: machine tools, gearboxes, pumps, compressors, transmission equipment and mechanisms with non-standard housings. In the Argentine market they are found in maintenance of production lines, food, metallurgical and process industries, where a failure stoppage forces you to obtain the exact reference. That is why code traceability is as important as the brand.
To select the replacement, start from the complete code engraved on the component or from the equipment documentation. Verify mounting dimensions, type of sealing, internal clearance and original lubrication. If the bearing works in a special housing, also check the fit and alignment between shaft and support. Careful cleaning of the seat and the use of the right tool prevent damage during mounting and extend service life.
Regarding equivalents, each manufacturer uses its own nomenclatures for special bearings, and a direct correspondence between brands does not always exist. Interchangeability is confirmed by comparing critical dimensions, load capacity and service conditions, not just the code. When the replacement is not exact, technical analysis of the assembly prevents premature failures. MR Accesorios Industriales can help you interpret the designation and find the right alternative.
If you have the bearing code at hand, send it by WhatsApp to MR Accesorios Industriales along with a photo or the main dimensions. With that data we can advise you on the corresponding SKF BT… B reference and clear up any doubts about mounting or interchangeability before the equipment goes back into operation.

Frequently Asked Questions
- What does the B suffix mean on an SKF BT… B bearing?
- The B suffix indicates a construction characteristic defined by SKF within this special line. It does not always mean the same thing across all series, so it is advisable to confirm its meaning with the complete code and the equipment documentation before replacing it.
- Can I replace a BT… B with a standard bearing?
- Only if the mounting dimensions, load capacity and service conditions match. As these are special bearings, a direct standard equivalent often does not exist. Always compare the critical dimensions and consult before substituting.
- How do I request the correct reference from MR?
- Send by WhatsApp the code engraved on the bearing, a photo and, if possible, the main dimensions of the housing and shaft. With that data MR Accesorios Industriales can advise you on the SKF BT… B reference that corresponds to your equipment.
