TIMKEN tapered roller bearings are components designed to withstand combined radial and axial loads. Their cone and cup geometry allows linear contact that distributes loads better. They are used in applications with significant forces and controlled misalignment, such as transmissions, wheel axles and industrial machinery. At MR Accesorios Industriales we supply them as an official brand and advise you on choosing the right one.
The designation of the X#M series is read as a code that combines an X prefix, a size number and the M suffix. For example, X30307M and X30311M share the final letter M, which usually indicates a construction or tolerance variant within the family. The middle number (30307, 30311) defines the size and main dimensions. Understanding this logic helps you quickly identify the bearing you need and order the correct replacement.
These bearings are used in industries such as automotive, metallurgy, cement and agro-industry. In Argentina they are commonly found in transmission boxes, reducers, wheel axles of agricultural machinery, earthmoving equipment and transport systems. They are also used in forklifts and port equipment, where combined loads and impacts are frequent. Their ability to withstand radial and axial forces makes them versatile in demanding environments.
To select the right bearing, take into account the radial and axial load, the rotation speed and the environmental conditions. Sealing is key: if there is dust or moisture, choose variants with seals. Lubrication must be adequate and mounting requires precise alignment to avoid premature wear. Respect the recommended internal clearance and verify the correct tightening. Careful mounting extends the bearing's service life and reduces unplanned downtime.
As for equivalents, tapered roller bearings from different brands can be interchanged if dimensions and load capacity match. Do not invent codes: always compare the dimensions and consult us if you have doubts. TIMKEN is a world reference, and at MR Accesorios Industriales we give you the technical support to find the compatible alternative. If the code you are looking for does not appear, write to us and we will indicate the right option.

Frequently Asked Questions
- What does the M suffix mean in the X#M series?
- The M suffix usually indicates a construction or tolerance variant within the tapered roller family. To confirm its exact meaning in the code you need, consult us on WhatsApp and we will advise you.
- How do I know if a bearing from another brand is equivalent?
- You must compare the main dimensions, the load capacity and the mounting type. Do not rely on the code alone. If you send us the dimensions or the original code, we will indicate the compatible alternative.
- What lubrication do you recommend for these bearings?
- Lubrication depends on speed, temperature and environment. For general applications lithium grease is used, but under extreme conditions a specific lubricant may be required. Consult us and we will guide you according to your case.
