The Timken M AH tapered roller cone is the inner assembly of a tapered roller bearing: the machined race that carries the rollers and cage and mounts on the shaft. Matched with its cup, it handles combined radial and axial loads, which makes it a common choice where rigidity and load capacity matter, such as industrial machinery, gear drives and transport equipment.
Reading the code helps you order the right piece. The M points to a metric-dimension family in the Timken catalog, while AH identifies a construction variant. A code such as M249749AH combines the M series, the size number 249749 and the AH suffix. With that logic, you can trace a replacement from the marking on the old cone or from the machine manual.
These cones show up in gearboxes, drive shafts, wheel hubs, road and earthmoving machinery, mills, machine tool spindles and railway equipment. They suit systems that see combined loads, vibration and changing conditions, so they are often specified where precision and robustness are required.
Selection comes down to the radial and axial load the position must take, the rotation speed and the environment. The cone must be assembled with its matching cup and aligned accurately. Grease or oil lubrication and effective sealing against contaminants both play a role in service life, and the recommended internal clearance should be respected.
Timken dimensions often line up with other major brands, but internal design and tolerances can differ. Before swapping brands, confirm the details with a specialist. Send the part number from the cone, cup or manual by WhatsApp or email and our team can suggest equivalents and help you choose. A photo or the data you have is enough if the number is worn.

Frequently asked questions
- What is the difference between a cone and a cup in a tapered roller bearing?
- The cone is the inner race mounted on the shaft, with the rollers and cage. The cup is the outer race that fits in the housing. They work as a matched set and should be replaced together.
- How do I identify the correct part number of my Timken bearing?
- Check the marking on the bearing itself, on the cup or on the cone, and the machine manual or spare parts list. If you cannot read it, send a photo or the data you have by WhatsApp and we will help you identify it.
- Are Timken bearings interchangeable with other brands?
- In many cases the dimensions match, but internal design and tolerances can differ. Send us the original part number and we will indicate a compatible alternative for your equipment.
