The cup is the outer ring of a tapered roller bearing: the raceway that receives the cone and mounts directly into the housing. In the TIMKEN L…-B designation, the letter L identifies the light series and the suffix B indicates a cup with specific wall and section within that family. It is used in assemblies where the cone and cup are selected separately to build the bearing according to the application.

The designation of these TIMKEN cups combines a series letter with a number and the suffix B: L102810-B, L116110-B, L305610-B, L357019-B, L467510-B, L507910-B, L624510-B and L630310-B are examples of that nomenclature. The L indicates the light family, the numeric block identifies the cup size and the suffix B distinguishes the section variant. To build the bearing, each cup must be combined with the corresponding cone of the same series.

In Argentine industry these cups are mounted on equipment where combined loads and axial thrust are demanding: gearboxes and gear cases, axles of road construction and agricultural machinery, conveyor belt rollers, milling machine and lathe spindles, and wheel hubs of material handling equipment. They also appear in process pumps, industrial fans and power transmission systems operating with controlled misalignment.

To select the correct cup, the cone-cup pair defined by the manufacturer must be respected: cups from different series are not interchangeable even if the outer diameter is similar. Mounting is done with an interference fit in the housing, and shaft alignment should be verified before closing the assembly. Lubrication, axial clearance and sealing are defined according to speed and working environment, and a poorly seated cup shortens bearing life.

Tapered roller cups are sold by designation system: each manufacturer uses its own letters and numbers, and equivalence is established by comparing dimensions and raceway angle, not the code. Therefore, to replace a TIMKEN cup with another brand, it is best to start from the actual housing dimensions and the cone already in service. MR Accesorios Industriales tells you the compatible alternative when you need it.

If you have the cup code or the complete bearing code, send it by WhatsApp to MR Accesorios Industriales along with a photo or the housing dimensions. With that we quote the corresponding TIMKEN cup or indicate the compatible alternative from another brand. We respond shortly.
