When a shaft has to carry both radial and axial forces in a single direction, an NSK tapered roller bearing is a common choice. Its cone-and-cup geometry creates line contact between the rollers and the raceways, which supports heavy loads and keeps the assembly rigid. You will find this type of bearing in gearboxes, wheel hubs and other demanding machinery. MR Industrial Accessories LLC supplies it so you can match the exact size your equipment requires.

The M A series code breaks down into three parts. The leading M tells you it is a single-row tapered roller bearing. The digits after it define the size and main dimensions. The trailing A marks a construction variant in the series, usually tied to a particular contact angle or cage style. Take M 86648 A as an example: the numeric block sets the bore and outer diameter, while the final letter points to the specific execution. Always order by the full part number that appears on your drawing or on the bearing you are replacing.

These bearings show up in food processing, metalworking, mining and plastics plants, in equipment such as conveyors, mills, presses, pumps and gearboxes. You will also find them in forklifts and power transmission systems. Because they take axial load in one direction only, they work best in opposed pairs, where two bearings handle forces in both directions.

Selection starts with sealing. Open, shielded and sealed versions each suit a different level of contamination. Lubrication matters just as much: the right grease in the right amount helps the bearing reach its expected service life. During mounting, aim for precise alignment, since these bearings do not tolerate angular misalignment well. In paired arrangements, set internal clearance with lock nuts or shims. If the shaft vibrates, check the fit and preload. Follow the manufacturer's mounting and commissioning instructions.

Tapered roller bearings carry different codes from one maker to another. If you have a part number from another brand, send it over and we can help you find a compatible replacement. The key is to match the main dimensions and the contact angle. Not every series swaps directly, so verify the complete designation. If the part has no markings, give us the shaft and housing measurements and we will guide you to the right bearing.
