The TIMKEN JS series tapered roller bearing cone is the inner race of a separable bearing: the rollers and cage rotate on it, and it is supported on the shaft cone. It is used together with the corresponding cup to form the complete assembly. It is a precision part for mountings that combine radial and axial loads, and it is chosen by part number according to the equipment where it is mounted.
The JS series designation is read as a catalogue code: the letters identify the cone family and the following numbers identify the size and design variants. For example, JS-3549A combines the series prefix with a base number and an alphabetic suffix that may indicate a modification of radius, angle or machining. To order the correct replacement, provide the complete code shown on the part or in the equipment manual.
These cones are mounted in single-row tapered roller assemblies and are used in gearboxes, transmission cases, road machinery shafts, material handling equipment and conveyor rollers. In the Argentine market they appear in maintenance of industrial plants, agricultural machinery workshops and mining equipment, where the cone and cup need to be replaced as a pair to preserve correct contact.
To select the cone, take into account the exact part number and the cup that accompanies it: the cone and cup of a tapered bearing are chosen as an assembly and mixing parts of different origin is not recommended. During mounting, verify shaft alignment, axial clearance and lubrication; incorrect adjustment or lack of lubricant accelerates wear of the races and rollers. If the equipment works with combined load, respect the clearance indicated by the equipment manufacturer.
Regarding equivalences, tapered bearings are identified by numbering systems that vary between manufacturers. The same size may have different designations depending on the brand, and they are not always interchangeable without verifying dimensions and angles. If you need to replace a TIMKEN cone, the safest approach is to compare the original code and the assembly measurements. From MR Accesorios Industriales we indicate the compatible alternative when applicable.
To request a quote for the TIMKEN JS series tapered roller cone, send us the complete code on WhatsApp, for example JS-3549A, and we will quote it promptly. If the equipment uses an assembled set, also send us the cup number or the gearbox model. We handle technical inquiries from workshops and plants throughout Argentina.

Frequently Asked Questions
- What is the difference between the cone and the cup of a tapered bearing?
- The cone is the inner race, where the rollers and cage are supported; the cup is the outer race that is 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. With that data we will quote the cone and, if necessary, the corresponding cup.
- Can I replace a cone from another brand with a TIMKEN one?
- Not always. Numbering systems change between manufacturers and dimensions or angles may differ. Verify the original code and the assembly measurements; we help you find the compatible alternative.
