Tapered roller bearings in the RKB LM series are built to carry radial and axial forces at the same time. The cone and cup arrangement creates linear contact that spreads the load across a wider area, which gives the bearing high capacity and stiffness. You will find them in gearboxes, wheel axles and other industrial equipment where precision and long service matter.
The LM prefix denotes a medium-section tapered roller series. Part numbers follow a cone/cup pattern, as seen in 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 first number after LM is the cone; the second is the cup. Each set is mounted as a matched unit and needs correct adjustment to reach the specified internal clearance.
These bearings appear in many industrial settings: transmission boxes, speed reducers, commercial vehicle wheel axles, agricultural machinery, earthmoving equipment and kiln roller systems. Because they take combined loads, they suit arrangements where radial and axial forces act together, such as helical gears or inclined shafts.
Choosing the right bearing means checking radial and axial load, rotation speed and operating environment. During mounting, the cone and cup must be precisely aligned; even small misalignments shorten service life. Grease or oil lubrication is possible, and the sealing method depends on contamination levels. Axial clearance is set with shims, nuts or spacers and then verified with a dial indicator.
For interchangeability, tapered roller bearings are identified by bore diameter, outer diameter and width. When replacing one, compare those dimensions and the contact angle. Equivalent series exist from makers such as Timken, SKF, FAG or NSK, but load ratings and suffixes can differ. Always confirm the full designation and tolerances.
To get a fast quote, send the complete bearing code—for example LM 12749/710—or the cone and cup measurements via WhatsApp. We reply quickly and can point you to a compatible alternative if you have a code from another brand. We also help with mounting and lubrication questions for your application.

Frequently asked questions
- What does the LM designation mean in a tapered roller bearing?
- LM identifies a medium-section tapered roller series. The numbers after LM, separated by a slash, are the cone and cup. For example, in LM 12749/710, the first number is the cone and the second is the cup. Keep the original assembly to maintain correct adjustment.
- How is a tapered roller bearing mounted?
- Mounting requires cleanliness, precise alignment and adjustment of axial clearance. Apply pressure only on the ring being mounted, never through the rollers. Use adequate lubrication and regulate clearance with nuts, shims or spacers. Check the clearance with a dial indicator before starting up.
- What should I consider when replacing a tapered roller bearing?
- When replacing, compare the main dimensions: bore diameter, outer diameter and width, and the contact angle. If you have the code from another brand, we can indicate the compatible alternative. Also consider load capacity and lubrication and sealing conditions. Send the code or measurements via WhatsApp for a quote.
