The TIMKEN JS series tapered roller cone is the inner race of a separable bearing. It carries the rollers and cage and mounts on the shaft, while the matching cup presses into the housing. Together they form a complete assembly for applications that handle combined radial and axial loads. Selection is made by part number based on the equipment.

The JS prefix identifies the cone family; the numbers and letters that follow indicate size and design variations. A code such as JS-3549A combines the series, a base number, and a suffix that may denote a change in radius, angle, or machining. Always provide the full code from the part or the equipment manual when ordering a replacement.

These cones are used in single-row tapered roller assemblies found in gearboxes, transmission cases, road machinery shafts, material handling equipment, and conveyor rollers. In plant maintenance, agricultural workshops, and mining operations, the cone and cup should be replaced as a pair to maintain proper contact.

When selecting a cone, note the exact part number and its matching cup. Tapered bearings are chosen as an assembly, and mixing components from different origins is not advised. During installation, check shaft alignment, axial clearance, and lubrication. Poor adjustment or insufficient lubricant speeds up wear on races and rollers. For combined loads, follow the clearance specified by the equipment manufacturer.

Tapered bearings use numbering systems that differ between manufacturers. The same size may carry different designations, and they are not always interchangeable without verifying dimensions and angles. To replace a TIMKEN cone, compare the original code and assembly measurements. We can suggest a compatible alternative when applicable.

To request a quote for a TIMKEN JS series tapered roller cone, send the complete code, for example JS-3549A, via WhatsApp or email. If the equipment uses an assembled set, include the cup number or gearbox model. We handle technical inquiries from workshops and plants across the United States and several Latin American countries.

Frequently asked questions

What is the difference between the cone and the cup of a tapered bearing?
The cone is the inner race that supports the rollers and cage; the cup is the outer race mounted in the housing. They are replaced as an assembly to maintain correct contact and clearance.
How do I order the TIMKEN JS series cone I need?
Send the complete code shown on the part or in the equipment manual via WhatsApp or email. With that data, we will quote the cone and, if needed, the corresponding cup.
Can I replace a cone from another brand with a TIMKEN one?
Not always. Numbering systems vary between manufacturers and dimensions or angles may differ. Verify the original code and assembly measurements; we help you find a compatible alternative.
