The cone is the inner half of a tapered roller bearing. It carries the inner raceway, the rollers and the cage, and it works together with the cup, which is the outer raceway. Timken's TS series covers single-row cones built for combined radial and axial loads. MR Industrial Accessories supplies this line and helps you match the right cone to your equipment.

TS cones use a base number of four or five digits followed by the letter C. Examples include 6559C, 6576C and 55175C. That C suffix marks the cone in this family. The base number does not run in sequence, because each reference stands for its own dimensional design. To pick the correct cone, cross it with the matching cup, which normally carries a different number. The number stamped on the part is the safest starting point for a quote.

Tapered roller bearings handle combined loads and moderate misalignment. You will find them in gearboxes, conveyor belts, mills, earthmoving equipment, vehicle axles and agricultural machinery, as well as in machine tool spindles and rolling mill rolls. The TS series spans many sizes, so it is common in plant maintenance and in repair shops that replace worn cones without changing the cup.

When choosing a TS cone, confirm the full part number and brand first. Assembly calls for clean conditions, proper lubrication and correct axial setting: tapered rollers run with controlled clearance, so they must not be too tight or too loose. Cone-to-cup alignment matters; misalignment speeds up wear. In dirty environments, add seals or oil seals. MR Industrial Accessories can guide you on lubrication and assembly for your application.

Timken is a leading name in tapered rollers, and cross-manufacturer equivalents exist for many series. Interchange is not automatic: two cones with similar dimensions can differ in contact angle, radius or tolerance. Quote by Timken part number or by assembly dimensions (inner diameter, outer diameter and width). If the exact number is missing, contact us and we will point you to a compatible option or review custom manufacturing.

To start your inquiry, send the cone part number by WhatsApp or email, for example 55187C or 72187C, and if possible a photo of the part plus its dimensions. With that information we reply promptly. MR Industrial Accessories serves customers across the United States and in several Latin American countries, and our team can suggest equivalents and help you choose.
