Tapered roller bearings in the RKB LM series are supplied as two separate pieces: the cone, which carries the rollers and cage on the inner ring, and the cup, the outer ring. This configuration lets the bearing take radial and axial forces at the same time, which suits equipment where heavy loads pass through the shaft. Typical installation points include gearboxes, machine shafts and general industrial machinery. MR Industrial Accessories LLC supplies this brand and quotes by exact part number.

Reading the code tells you what you are ordering. Take LM 361649 A/610: LM is the dimension series, 361649 is the cone, 610 is the cup, and the A suffix flags an internal design variant. The same logic applies to LM 742747 A/710, where 742747 is the cone, 710 the cup and A the variant. With that breakdown you can order the full assembly or just the component you need.

In US plants and workshops, LM series bearings turn up in gearboxes, reducers, drive shafts, road machinery, material handling equipment and conveyor rollers. Railway and agricultural machinery also use them, since those duties bring combined and shock loads. Because cone and cup separate, assembly and replacement on large equipment is simpler.

Selection comes down to radial and axial load, rotational speed and the lubrication method. During mounting, axial clearance is set by advancing the cone along the shaft or setting the cup back in the housing. Alignment must be precise and sealing adequate to keep contamination out. Grease or oil both work, depending on the operating regime and the environment.

Tapered roller bearings are made to international standards covering dimensions and tolerances, so brands can be interchanged. To replace a bearing from another maker, send the part number or the dimensions and we will identify the compatible equivalent. MR Industrial Accessories LLC helps you confirm that the substitution is correct and safe.
