The TIMKEN JM series tapered roller cone is the inner ring assembly, with rollers and cage, that fits on the shaft and runs with a matching cup. It handles combined radial and axial loads, so it is common in equipment where the shaft needs accurate guidance. MR Industrial Accessories supplies this brand and can help you confirm the right cone for your application.
The JM code tells you the series and size. In a number like JM205149A, the JM prefix identifies the series, the digits that follow set the size position, and the final A marks a design variant. The same pattern applies to JM207049A, JM714249A, JM718149A and JM736149A. When ordering, use the full part number from the equipment or manual rather than a shortened version.
These cones are found in gearboxes, conveyors, mills, presses and agricultural machinery, as well as in automotive and heavy transport work. Their tapered roller geometry lets them take radial and axial loads at the same time, which suits assemblies that need precise shaft location. Selection depends on shaft diameter, load type and lubrication conditions.
The cone is mounted with its corresponding cup, which is not included unless you order the complete assembly. Check alignment and axial clearance during installation; poor adjustment speeds up wear. Use the specified lubrication, and add sealing where dust or moisture is present to protect the raceway. For high-speed operation, confirm the tolerances before you buy.
TIMKEN JM series cones may interchange with other brands that follow the same nomenclature and dimensions, but not every part number is equivalent. Compare the complete number and check the angle and width. MR Industrial Accessories supplies TIMKEN and also offers alternatives from other manufacturers. If you cannot find your reference, send the part number or model via WhatsApp or email and the team will reply promptly, suggest equivalents and help you choose.

Frequently asked questions
- What is the difference between the cone and the cup of a tapered roller bearing?
- The cone is the inner ring with rollers and cage that mounts on the shaft. The cup is the outer ring that fits in the housing. They work as a set and should be replaced together.
- How do I identify the TIMKEN JM series cone my equipment needs?
- Check the part number on the old cone or in the equipment manual. If it is not readable, send a photo or the shaft and housing measurements via WhatsApp and the team will help you identify it.
- Are TIMKEN JM series cones interchangeable with other brands?
- They may interchange with other brands that use the same nomenclature and dimensions, but you must verify the complete part number and tolerances. Not all equivalent numbers are identical. Ask via WhatsApp and the team will indicate a compatible alternative.
