RKB tapered roller bearings are separable units made up of a cone and a cup that work together to carry radial and axial loads in a single direction. Their design with rollers guided by the cone rib makes them suitable for combined demands in industrial machinery. MR Accesorios Industriales sells this line: send us the part number and we will quote it for you on WhatsApp.
The designation of this series is expressed as JL 286948/JL 286910, where the first part identifies the cone and the second the cup. The numbers that follow the letters JL correspond to standardized dimensions: in the examples JL 286948/JL 286910 and JL 286949/JL 286910, the cone changes while the cup stays the same, which allows different combinations of width and capacity. To order the correct replacement, simply state the complete part number as it appears on the original assembly.
These bearings are used in applications with simultaneous radial and axial loads, such as reducers, drive shafts, road machinery, crushing and conveying equipment. In Argentine industry they appear in maintenance at cement, food, mining and agro-industrial plants. Their ability to work with controlled misalignment and withstand thrust makes them common in conveyor belt rollers and gearboxes.
To select the right bearing, take into account radial and axial load, rotational speed and environmental conditions. Assembly requires cleanliness, verification of housings and shafts, and adequate lubrication: grease or oil depending on the case. Alignment between cone and cup is critical; misaligned assembly shortens service life. If the equipment works with contaminants, consider complementary seals or radial shaft seals. Always follow the machine manufacturer's recommendations.
When replacing a bearing from another brand, the safest approach is to compare by dimensions and by the complete part number. Equivalences between manufacturers are established by cone and cup dimensions, not only by the nomenclature. If you have the original part number or the part on hand, send us the data and we will tell you the compatible alternative. Not all series are interchangeable between brands, so it is best to verify before buying.
If you need a quote for an RKB tapered roller bearing, write to us on WhatsApp with the part number JL 286948/JL 286910, JL 286949/JL 286910 or the one shown on your equipment. At MR Accesorios Industriales we reply promptly with the quote and the options available for your application.

Frequently Asked Questions
- How do I identify the tapered roller bearing I need?
- The complete part number includes cone and cup, for example
JL 286948/JL 286910. If you do not have it, measure the bore, outer diameter and width, and send us those data. You can also send us a photo of the part or the assembly so we can help you identify it. - What applications do RKB tapered roller bearings have?
- They are used in reducers, drive shafts, road machinery, conveyor belts and crushing equipment. They carry combined radial and axial loads, which is why they are common in the cement, mining, food and agro-industrial industries. The choice depends on the load and the operating speed.
- How is a tapered roller bearing correctly mounted?
- Assembly requires cleanliness, precise alignment and adequate lubrication. Check the condition of the shaft and housing before installing. Preload or axial clearance must be adjusted according to the application. Incorrect assembly causes premature wear. Always follow the equipment manufacturer's instructions.
