The LM series tapered roller bearing is a component designed to support combined radial and axial loads. Its cone and cup geometry allows linear contact that distributes the load over a larger surface, resulting in high load capacity and rigidity. It is used in applications where precision and durability are critical, such as gearboxes, wheel axles and industrial machinery. At MR Accesorios Industriales we sell the RKB brand, with size and configuration options for different needs.

The LM series designation is interpreted from the examples: LM 11749/710, LM 11949/910, LM 12748/710, LM 12749/710, LM 12749/711, LM 29748/710, LM 29749/710 and LM 29749/711. The prefix LM identifies the medium-section tapered roller series. The numbers that follow, separated by a slash, correspond to the cone and the cup. Each assembly is mounted as a unit and requires proper adjustment to achieve the recommended internal clearance.

These bearings are used in a wide variety of industries in Argentina. They are found in transmission boxes, speed reducers, commercial vehicle wheel axles, agricultural machinery, earthmoving equipment and roller systems for kilns. Their ability to support combined loads makes them suitable for applications where radial and axial forces occur simultaneously, such as in helical gears or inclined shafts.

To correctly select a tapered roller bearing, it is essential to consider the radial and axial load, the rotation speed and the environmental conditions. Mounting must ensure precise alignment between the cone and the cup, since misalignments greater than a few arc minutes reduce service life. Lubrication can be with grease or oil, and sealing will depend on the contamination present. Axial clearance is adjusted using shims, nuts or spacers, and must be verified with a dial indicator.

Regarding equivalences and interchangeability, tapered roller bearings are identified by their main dimensions: bore diameter, outer diameter and width. When looking for a replacement, it is necessary to compare these measurements and the contact angle. Brands such as Timken, SKF, FAG or NSK offer equivalent series, but each manufacturer may have variations in load capacity and suffixes. It is always advisable to verify the complete designation and tolerances.

To receive an accurate quote, send via WhatsApp the complete bearing code you need, for example LM 12749/710, or the cone and cup measurements. At MR Accesorios Industriales we quote you promptly and indicate the compatible alternative if you have the code from another brand. We can also advise you on mounting and the appropriate lubrication for your application.
