For shafts that must be located accurately while carrying both radial and thrust forces, the RKB LL series provides a separable tapered roller bearing arrangement. Each unit consists of a cone assembly and a cup that are matched to work as a pair, which is why they are installed in opposed positions on a shaft.
The part number tells you which components belong together. Take LL 483448/418: the digits before the slash identify the cone, and those after it identify the cup. The same pattern applies to LL 566848/810 and LL 639249/210. Because the cone and cup are manufactured as a set, always order using the full code stamped on the bearing.
Typical installations include gear reducers, power transmission drives, cranes, conveyors, road equipment and farm machinery. Where a shaft needs precise axial location under moderate speed and combined loading, this series is a common choice.
Selection depends on the radial and axial loads, the speed, and the lubrication method. Correct alignment between cone and cup during mounting is critical; angular misalignment will shorten service life. Grease or oil can be used, and in dirty or damp conditions, additional seals help keep the raceways clean.
If you are replacing a bearing from another manufacturer, we can cross-reference it. Provide the code from the old part or the cone and cup dimensions, and we will identify the RKB LL equivalent or a suitable alternative. Our team assists with selection and can suggest interchangeable options.
MR Industrial Accessories supplies the RKB LL series to customers across the United States and in several Latin American countries. To request a quote, send the part number via WhatsApp or email. If you need a non-standard size, share the dimensions and we will help you find the right bearing.

Frequently asked questions
- What does the LL prefix indicate?
- The LL prefix denotes a specific family within the RKB tapered roller bearing range. The complete code, including the numbers before and after the slash, identifies the matched cone and cup.
- Can these bearings be used alone?
- No. Tapered roller bearings handle axial load in one direction, so they must be mounted in opposed pairs to manage thrust in both directions and set proper clearance.
- How can I find an equivalent for a different brand?
- Contact us on WhatsApp with the part number you need to replace. We will provide the compatible RKB LL reference or another option that fits your application.
