The RKB TDI series is a two-row tapered roller bearing built to take radial and axial forces from either direction. Gearboxes, machine tool spindles and mining machinery are typical homes for this design, where stiffness and load capacity matter. MR Industrial Accessories supplies this line and can help you match the right designation to your equipment.
In the TDI code, the letters point to a two-row tapered roller arrangement that pairs a double cone with a single cup. The trailing digits, such as TDI 328283 or TDI 328306, set the size and internal proportions. Every code covers its own bore, outside diameter and width, so those figures do not carry over to another series. For a replacement, forward the full code from the bearing or the machine manual.
You will find these bearings in speed reducers, conveyor rollers, mills, presses and material handling equipment, as well as in agricultural and road machinery. Their capacity for combined loads and moments suits shafts that need rigidity even when alignment is less than perfect.
When specifying a TDI, review the radial and axial loads, the speed and the lubrication method. Installation calls for clean conditions, sound housings and a controlled axial setting to reach the right internal clearance. Grease or oil can be used depending on the surroundings; in dirty environments, extra sealing helps. Cone and cup must line up properly to prevent point loading.
RKB TDI bearings can be swapped with equivalent assemblies from other makers that use the same dimensional naming. If the code is unreadable, the bore, outside diameter and total width allow identification. With those measurements, we can point you to a compatible option. Always confirm tolerances and axial clearance before fitting.
To get a TDI bearing for your equipment, message us on WhatsApp with the code or the dimensions. MR Industrial Accessories replies quickly, helps with the application and can advise on mounting and lubrication so the bearing runs under the right conditions.

Frequently asked questions
- What does the TDI designation mean on an RKB bearing?
- TDI refers to a two-row tapered roller bearing with a double cone and a single cup. The numbers that follow, like TDI 328283, define the size and proportions. Each code matches a specific bore, outside diameter and width.
- How do I choose the replacement if I don't have the original code?
- Measure the bore, the outside diameter and the total width. With those dimensions, we can suggest a compatible reference. The number on the bearing or in the machine manual also works.
- What lubrication is recommended for a TDI bearing?
- It depends on speed and environment. Many applications use high-load grease; high speeds or elevated temperatures may call for oil. Keep the lubricant clean and renew it on schedule. In dusty or humid areas, additional sealing protects the assembly.
