A TIMKEN JLM series tapered roller cone is the inner portion of a separable bearing assembly, containing the cone, cage and rollers. It mounts on the shaft and pairs with a matching cup to complete the bearing. This component handles combined radial and axial loads in agricultural equipment, transport machinery and power transmission drives.
The JLM prefix identifies the tapered roller cone family. The following digits define size and geometry, and a trailing letter such as A in JLM104942A or JLM506849A marks a design variant. For correct selection, use the full part number from the bearing or the equipment manual.
Typical applications include gearboxes, reducers, wheel hubs, road construction machine rollers and material handling equipment. The cone's ability to take simultaneous radial and axial loads suits shafts operating under combined stresses where precise fitting matters.
Selection depends on the cup it will be matched with. The cone-cup pair sets internal clearance and load capacity. Proper installation requires clean conditions, correct lubrication and careful alignment. In dusty or humid environments, evaluate sealing. Adjust preload or clearance according to the equipment manufacturer's instructions.
Tapered roller bearings carry a manufacturer's part number, and other brands may offer dimensional equivalents. For replacement, compare the original part number and assembly dimensions. If you provide the part number or bearing dimensions, we can indicate a compatible alternative.

Frequently asked questions
- What is the difference between a cone and a cup in a tapered roller bearing?
- The cone is the inner ring with rollers and cage; the cup is the outer ring. They mount separately and form a separable assembly. For replacement, identify both part numbers and keep the original combination.
- How do I know which TIMKEN cone my equipment needs?
- Check the part number engraved on the old bearing or in the equipment manual. If unavailable, send us the shaft and housing dimensions. With that data we will quote the correct cone.
- Do TIMKEN bearings have equivalents from other brands?
- Yes, other brands make tapered roller bearings with similar dimensions. Interchangeability depends on tolerances and design. We can indicate a compatible alternative based on the original part number.
