The NSK tapered roller bearing is a component designed to support radial and axial loads in one direction. Its tapered geometry allows linear contact between rollers and raceways, which gives it high load capacity and rigidity. It is used in applications where significant forces must be transmitted, such as gearboxes, wheel axles and heavy machinery. At MR Accesorios Industriales we sell it so you can complete your assembly with the exact size you need.

The M A series designation reads as follows: the letter M indicates that it is a single-row tapered roller bearing, and the number that follows identifies the size and main dimensions. The suffix A indicates a construction variant within the series, generally associated with a specific contact angle or cage design. A concrete example is M 86648 A, where the numeric code defines the bore and outer diameter, and the final letter distinguishes the execution. To select the correct one, always use the complete part number shown on the drawing or on the original part.

These bearings are used in industries such as food processing, metalworking, mining and plastics, in equipment such as conveyor belts, mills, presses, pumps and gearboxes. In Argentina, they are commonly found in agricultural machinery, especially in seeders and harvesters, where axles support combined loads and demanding working conditions. They also appear in forklifts and power transmission systems. Their ability to support axial loads in one direction makes them ideal for paired arrangements, where two opposed bearings absorb forces in both directions.

To choose the right bearing, take into account the type of sealing: there are open ones, with shields or with seals, and each adapts to different levels of contamination. Lubrication is key: a good quality grease and the correct amount extend service life. Mounting must ensure precise alignment, since these bearings are sensitive to angular misalignment. Internal clearance also matters: in paired applications, it is adjusted using lock nuts or shims. If the shaft works with vibrations, it is advisable to verify the fit and preload. Always follow the manufacturer's recommendations for mounting and commissioning.

Regarding equivalences, tapered roller bearings are identified by codes that vary between manufacturers. If you have the part number of another brand, we can help you find the compatible replacement. What matters is respecting the main dimensions and the contact angle. Not all series are directly interchangeable, so it is essential to verify the complete designation. If the part has no identification, send us the shaft and housing measurements, and we will advise you to find the bearing you need.
