SKF special bearings in the BC…B … series are components designed for applications that require a particular configuration, outside conventional standards. They are used when mounting, load or speed conditions demand a specific geometry that cannot be solved with general catalogue bearings. MR Accesorios Industriales supplies this line as an official brand, backed by more than 80 years in the Argentine industrial market.
The designation BC…B … identifies these special bearings within the SKF system. The prefix BC usually indicates an execution for specific applications, while the numeric block that follows (as in BC1B 320298 or BC1B 320811) corresponds to an internal code that defines particular dimensions and characteristics. Unlike standard series, these codes do not follow a public dimensional progression, so each reference must be checked against its drawing or technical specification. It is essential to verify the complete code before requesting a quote.
These bearings are used in equipment where mounting space is critical or operating conditions are demanding: gearboxes, machine tool spindles, mining equipment, steelmaking and continuous process plants. In Argentina, they are commonly found in machinery imported from Europe or the United States, where the original manufacturer defined a special bearing to guarantee performance. They are also used in retrofits or replacements where it is not possible to modify the housing or the shaft.
To select the correct replacement, the code alone is not enough: you must confirm bore dimensions, outside diameter, width, sealing type, internal clearance and lubrication. Many of these bearings have special tolerances or predefined clearances that affect operation. During mounting, follow the specified fitting method (press, induction or hot oil) and verify alignment between housings. Poor alignment shortens service life even in high-quality bearings.
Interchangeability between brands for special bearings is limited: each manufacturer defines its own codes and dimensions. In general, an SKF BC…B … cannot be replaced by an equivalent from another brand without checking the drawing thoroughly. If the original bearing is not available, the alternative is to analyze the function in the equipment and look for a replacement that meets the same load, speed and environment conditions. MR Accesorios Industriales can help you with that technical analysis.
If you have the code BC1B 320298, BC1B 320811 or any other reference in the series, send us your inquiry by WhatsApp. At MR Accesorios Industriales we guide you so you reach the correct bearing, with the documentation needed to validate the application. Avoid improvised replacements that put the equipment at risk.

Frequently Asked Questions
- What does the designation BC…B … mean on an SKF bearing?
- It is an SKF internal code for special bearings. The BC prefix and the numeric block identify a particular execution that does not follow the standard dimensional nomenclature. To know the exact measurements, you must check the drawing or the technical data sheet for the specific code.
- Can I replace an SKF BC…B … with another brand?
- In general, not directly. Special bearings have dimensions and tolerances defined by each manufacturer. Substitution requires checking the drawing thoroughly and confirming that the replacement meets the load, speed and mounting conditions of the equipment.
- How do I request a quote for these bearings from MR?
- Send the complete code by WhatsApp, for example BC1B 320298, together with a photo of the bearing or the drawing if you have it. That way we can identify the exact reference and advise you on the best option for your application.
