A tapered roller bearing is built from two matched pieces, and the cone is the machined inner race that presses onto the shaft. Paired with its cup, it carries radial and axial forces at the same time, which is why it shows up in equipment where alignment and load capacity matter. MR Industrial Accessories LLC supplies this TIMKEN JLM series line to maintenance and purchasing teams throughout the United States and Latin America.

Reading the code helps you narrow down a replacement. The JLM prefix marks a family of light-to-medium section tapered roller bearings, and the digits that follow set the main dimensions. Part numbers such as JLM67042, JLM104948 and JLM506849 each point to one specific cone inside that family.

You will find these cones in gear reducers, road machinery axles, earthmoving equipment, conveyors, mills, presses and rolling mill rolls. They also serve the agro-industrial sector in seeders and harvesters, plus metallurgical and cement plants. Because they take radial and axial forces at once, they suit shafts that see both kinds of load simultaneously.

Selection starts with the radial and axial load the position must carry, then the rotation speed and the surrounding conditions. The cone is fitted onto the shaft, usually with interference, and must line up precisely with its cup. Grease or oil lubrication and effective sealing both influence how long the assembly lasts. Under vibration or high temperatures, match the lubricant and internal clearance to the manufacturer's recommendations.

TIMKEN tapered roller bearings interchange with other brands built to the same standardized dimensions. For a quote, give the full cone and cup part numbers, or the bore, outer diameter and width. If the exact reference is hard to trace, MR Industrial Accessories LLC can point you to a compatible option. Tolerances and internal design differ between makers, so verifying the complete assembly is always worthwhile.

Send the part number or your equipment measurements by WhatsApp or email and the team will reply promptly with a quote and, where needed, an equivalent. They can also walk you through mounting and lubrication so the bearing performs as intended.
