RKB tapered roller bearings are built for applications where radial and axial forces act at the same time. The angled rollers and raceways create linear contact, which spreads the load across the bearing. You will find them in gearboxes, machine shafts, and other industrial equipment that sees heavy forces. MR Industrial Accessories LLC supplies this brand and helps you match the right bearing to your application.

A tapered bearing code has two parts separated by a slash: the first is the cone, the inner assembly with rollers and cage, and the second is the cup, the outer ring. Take 15103 S/15243 and 15103 S/15245: both use a 15103 cone but pair it with different cups. The S on the cone can point to a design or tolerance variation. Because the cone-and-cup set fixes the mounting dimensions, you need both codes to order a correct replacement.

These bearings appear in speed reducers, transmission boxes, machine tool shafts, mining equipment, cement plants, and food plants. Conveyor rollers, overhead cranes, and agricultural machinery also use them. Their design suits simultaneous radial and axial forces, as seen in helical gears or inclined shafts.

When selecting a bearing, consider the radial and axial load, the rotation speed, and the operating environment. Mounting calls for careful alignment and correct adjustment of axial clearance, which is set by moving the cup or the cone. Grease or oil can be used for lubrication depending on the application, and keeping the lubricant clean matters to avoid contamination. Seals and oil seals keep dust and moisture out, which helps the bearing last longer.

Tapered roller bearings follow international standards, so components can be interchanged between brands when dimensions and contact angle match. To replace a bearing from another brand, send the full code or the main dimensions (inner, outer, and width diameter) and we will point you to a compatible option. MR Industrial Accessories LLC supplies the RKB brand and can quote the exact code you need.
