The NSK M series tapered roller bearing cone is the inner assembly of a tapered roller bearing, made up of the inner ring, the rollers and the cage. It handles radial and axial loads together and provides high rigidity. MR Industrial Accessories supplies this series to customers throughout the United States and in several Latin American countries.

The M at the start of the designation tells you which cone you are looking at. Part numbers such as M 84249, M 84548, M 86643, M 86647 and M 236849 all follow the same pattern: the letter M followed by a numeric code. Each code belongs to one specific cone, and that cone pairs with its matching cup to make a complete bearing. When you place an order, the exact part number is what identifies the part.

You will find these cones in automotive, metallurgical, food processing and mining operations. Typical equipment includes transmission cases, gear reducers, wheel axles, agricultural machinery and conveyors. Fleets, rail maintenance and heavy machinery repair are common applications. Because the cone takes combined loads, it fits positions where a single-direction bearing would not hold up.

Selection comes down to two things: the dimensions and the load capacity the position requires. During assembly, use the right tools, verify alignment and set the axial clearance correctly. Lubrication should follow the manufacturer's specification, and keeping the work area clean prevents contamination. A proper seal also helps the bearing reach its expected service life.

Cones from different brands can be swapped when the dimensions and the contact angle match. NSK is a recognized bearing brand, and MR Industrial Accessories supplies its products. If you have a part number from another maker, we can point you to the equivalent. Confirm compatibility before you install a replacement.
