Tapered roller bearings from TIMKEN are built for duties where radial and axial forces act at the same time. The cone and cup arrangement creates linear contact between rolling elements and raceways, which spreads the load across the assembly. Typical installations include transmissions, wheel axles and general industrial machinery where forces are high and misalignment stays within controlled limits. We supply these bearings and help you match the right reference to your application.

The X…M designation works as a code: an X prefix, a size number in the middle and the M suffix at the end. Two examples make the pattern clear, X30307M and X30311M, both closing with M, which generally points to a construction or tolerance variant inside the family. The digits 30307 and 30311 set the size and the main dimensions. Reading the code this way makes it easier to spot the bearing you need and to order the correct replacement.

You will find these bearings in automotive, metallurgy, cement and agro-industrial operations. They appear in gearboxes and reducers, in wheel axles of farm machinery, in earthmoving units and in conveyor systems. Forklifts and port equipment also rely on them, since combined loads and shock are part of daily work there. Handling radial and axial forces at once is what makes them useful in these conditions.

Selection starts with the radial load, the axial load, the rotation speed and the environment. Sealing matters: where dust or moisture is present, sealed variants are the better choice. Lubrication has to suit the duty, and mounting calls for precise alignment so wear does not appear early. Keep to the specified internal clearance and check tightening. A careful installation is what keeps the bearing running and avoids unexpected stoppages.

On interchangeability, tapered roller bearings from different manufacturers can replace one another when dimensions and load capacity correspond. TIMKEN is a widely recognized reference, and we provide technical support to locate the compatible option. If a part number is not listed, send it to us and we will point you to the right choice.
