RKB LL series tapered roller bearings are separable units made up of a cone (inner ring with rollers and cage) and a cup (outer ring). They are designed to carry radial and axial loads in one direction, so they are mounted in opposed pairs. They are used in applications that must transmit considerable forces with shafts rotating at moderate speeds.

The designation of this series combines the prefix LL with a numeric code that identifies each assembly. In the examples, LL 483448/418, LL 566848/810 and LL 639249/210, the first number corresponds to the cone number and the second, separated by a slash, to the cup number. This relationship indicates that the cone and cup are supplied as a matched pair. To order the replacement, it is enough to provide the complete code engraved on the bearing.

These bearings are used in power transmission equipment, speed reducers, gearboxes, road machinery, cranes, conveyors and agricultural machinery. In the Argentine market, they are commonly found in agricultural implements, earthmoving equipment and industrial production lines. Their ability to combine radial and axial loads makes them suitable for assemblies where the shaft must be guided with precision.

To select the correct bearing, take into account the radial and axial load it will carry, the rotational speed and the type of lubrication. Mounting must ensure careful alignment between cone and cup, since angular misalignment accelerates wear. Lubrication can be grease or oil, depending on the environment; in dusty or humid environments, it is advisable to choose additional seals to protect the raceways.

When looking for a replacement, it is common to compare designations between different manufacturers. The RKB LL series can be interchanged with bearings from other origins that share the same dimensions and contact angles. If you have the code from another brand, send it and we will indicate the compatible equivalent. We can also quote the exact size you need if you provide the cone and cup dimensions.
