The TIMKEN LL series tapered roller cone is the inner ring assembly of a separable bearing, built to handle combined radial and axial loads with high capacity and rigidity. It is common in agricultural equipment, transport fleets, and industrial power transmission drives. MR Industrial Accessories supplies this brand and helps you match the right cone to your application.

Read the LL series code together with the full part number, such as LL450749AA. The first letters set the dimension series, the following digits define the size, and the final letters can point to design or tolerance variations. Here, the AA suffix typically signals a change in finish or tolerances. Always pair the cone with its matching cup, because the two parts work as one assembly.

Typical uses for tapered roller bearings include truck and trailer wheel hubs, gearboxes, milling equipment, seeders, and harvesters. Their ability to take combined loads suits demanding settings with shocks and vibration. In metallurgical and mining operations, they appear in conveyors and crushers. Machine tools and earthmoving equipment also rely on them where precision and durability matter.

When choosing a cone, consider the radial and axial load, rotation speed, and environmental conditions. Installation calls for careful alignment and proper lubrication, usually grease or oil. Sealing is critical to keep contamination out and lubricant in. Check internal clearance and set it to the manufacturer's specifications; poor assembly can shorten bearing life and affect equipment performance.

On interchangeability, tapered roller bearings from different brands may be interchangeable when dimensions and contact angle match. Even so, using cone and cup assemblies from the same brand is advisable for the best fit. TIMKEN is a global reference in this technology, and MR Industrial Accessories supplies it as a brand. If you are replacing an existing bearing, we will point you to the alternative compatible with your part number.
