Tapered roller bearings from RKB come as two separate pieces: the cone, which carries the rollers and cage on the inner ring, and the cup, the outer ring. Because each unit accepts radial and axial force in a single direction, they work in opposed pairs. Gearboxes, wheel axles and transmission machinery are typical homes for this design. MR Industrial Accessories supplies them and quotes by part number through WhatsApp or email.
Reading a tapered bearing number is easier once you know it is written as a fraction. Everything ahead of the slash belongs to the cone, everything behind it to the cup. Take 462/453 X, 535/532 X or 539/532 X: the two halves arrive as a matched set. A trailing X tells you the outer dimensions follow the international standard, which is what makes cross-brand interchange possible. With that logic in hand, you can order the right replacement even when only one of the two numbers is legible on the part.
These bearings turn up wherever loads are mixed rather than purely radial: speed reducers, transmission boxes, the wheel axles of road and agricultural equipment, machine tools, large pumps and fans. Helical and bevel gear arrangements are a common fit, since the mesh pushes both radially and axially. Food processing, cement, mining and metalworking operations rely on them for the same reason.
Selection starts with the radial and axial load the position must carry, then the rotation speed and the space you have. Installation calls for good alignment and controlled axial adjustment: two bearings opposed, with clearance set by nuts, shims or covers. Grease or oil both work as lubricant, and the seal should match the environment around the housing. An interference fit on the cone paired with a sliding fit on the cup keeps disassembly practical.
Replacements often cross over between brands, because tapered roller bearings of the same standardized dimensions are made by several manufacturers. Send the number from another brand, or an unidentified part, and we will point you to the compatible option. What actually governs interchange is the cone and cup dimensions, not the catalog number, so confirm diameters and total width before you install.
To get a quote on the RKB tapered roller bearing you need, message us the complete part number on WhatsApp. If the designation is unclear, a photo of the part or the cone and cup measurements works just as well, and we will come back to you promptly with the matching option.

Frequently asked questions
- What does the designation 462/453 X mean?
- The digits before the slash name the cone, those after it name the cup, and the X shows the dimensions are standardized. It is a separable set used as one unit. Send the full number or your measurements to order.
- How are tapered roller bearings mounted?
- Two bearings go in opposition so axial load is covered in both directions. The cone fits with interference on the shaft, the cup slides in the housing, and nuts, shims or covers set the axial clearance.
- What lubrication do they need?
- Grease or oil, chosen according to speed and environment. Oil is often preferred in industrial service for heat dissipation. Keep the lubricant clean and check the seal to keep contamination out.
