A tapered roller bearing cone is the inner assembly that sits on the shaft: the inner ring, the rollers and the cage. In the NSK LM series you will find cones built for equipment where radial and axial forces act at the same time. MR Industrial Accessories LLC supplies these cones as individual components, so you can swap out a worn inner assembly or build up a set together with its matching cup.

Reading the code is the first step in getting the right part. Take LM 67043, LM 72849, LM 522546, LM 522548 and LM 522549: the LM prefix marks the family, and the digits that follow separate one cone size and geometry from another. Keep in mind that a cone is not a complete bearing. It is the inner ring with its rollers and cage, and it only works once paired with the cup pressed into the housing.

Where does this type of cone show up? Gearboxes, conveyor systems, road and earthmoving machinery, pumps and transmissions on production floors, plus agricultural equipment and mining installations. All of these rely on tapered roller bearings to carry combined loads, and all of them call for careful adjustment at assembly. MR Industrial Accessories LLC keeps NSK within its bearing line for replacement work and for assembling complete sets.

Selection depends on matching the full code and series, since cone and cup are engineered as a pair. At mounting time, lubrication and axial clearance are the two factors that decide how long the assembly lasts; a clearance that is too tight or too loose wears the rollers and raceways faster. Shaft-to-housing alignment deserves the same attention, and the sealing should be inspected so that dirt and moisture stay out. When the cone arrives with a metal cage, turn the rollers by hand before installation to confirm they move freely.

A cone from any manufacturer is identified by its designation and by the dimensions of the cone-cup set. If a customer comes to us with a competitor's code or a part that carries no identification, the match can be traced through dimensions and through the number stamped on the cone. Sending the code, a photo and the main measurements is the fastest way to guide that search.
