For equipment that handles both radial and axial forces at once, the RKB T4CB series provides a tapered roller bearing solution. Its tapered raceways and guided rollers create linear contact that spreads the load across a wider area. You will find these bearings in gearboxes, drive shafts and other industrial machinery where precision and load capacity matter.

The T4CB code breaks down into three parts: T for tapered roller bearing, 4 for the dimension series, and CB for internal design details such as contact angle or cage style. The trailing number—seen in T4CB 100, T4CB 110, T4CB 120, T4CB 130 and T4CB 140—points to the size or the bore-and-width combination. When picking a code, check your shaft dimensions and the space available in the housing.

These bearings show up in gearboxes, speed reducers, drive shafts, conveyor rollers, road machinery and agricultural equipment. They also serve in metallurgical, cement and mining operations where loads are heavy and conditions are tough. Because they handle combined loads, they suit assemblies that demand precise shaft alignment and high rigidity.

Selecting the right T4CB bearing means looking at the radial and axial loads, the rotation speed and the operating environment. Mounting calls for exact raceway alignment and correct internal clearance, which is set by axially shifting one raceway. Grease or oil lubrication works depending on the application, and the seal must keep out contamination and hold in lubricant. Poor installation can shorten bearing life.

Tapered roller bearings follow international standards, so you can swap brands when the main dimensions and contact angle line up. For a replacement, compare bore, outer diameter, total width and raceway angle—not just the first two. If you share the original part code or the assembly dimensions, we can point you to the right equivalent.

Frequently asked questions

What does the T4CB designation mean on RKB bearings?
T stands for tapered roller bearing, 4 is the dimension series and CB covers internal design variants. The final number, like 100 or 110, identifies the size. Match these dimensions to your assembly when choosing a code.
How is a T4CB tapered roller bearing mounted?
Mount it with precise alignment and set the axial clearance by displacing one raceway. Lubricate properly and seal against contamination. Follow the manufacturer's instructions for mounting and startup.
Can I replace a bearing from another brand with an RKB T4CB?
Yes, if the main dimensions and contact angle match. Tapered roller bearings are made to standards that allow interchangeability. Send the original code or dimensions and we'll identify the equivalent.
