The TIMKEN TSF tapered roller cup is the outer race of a tapered roller bearing, designed to be press-fitted into the housing. Together with the cone, it forms a unit that handles combined radial and axial loads. You will find it in gearboxes, pumps, conveyors and agricultural equipment where shafts run at moderate speed with controlled misalignment.

The cup carries a basic number plus the suffix -BA, as in 553-BA. That number defines the dimension series, while -BA indicates a construction variant in the TSF family. To order the right cup, send the full part number from the bearing or the equipment drawing.

Typical applications include gear reducers, conveyor belts, mills, mixers, presses and material handling equipment in food processing, cement, mining and agriculture. The cup also appears in automotive and railway assemblies, where combined radial and axial loads call for a robust, serviceable bearing.

When selecting a cup, check the outer diameter, width and raceway angle against the matching cone. Mount with a press or controlled impact tools; never strike the raceway directly. Clean lubrication and effective sealing keep contamination out. Misalignment between cone and cup creates point loads and early failure, so alignment matters.

Cups are interchangeable across brands when the standardized dimensions and raceway angle match. To replace one, compare the complete part number and the main dimensions. If you are unsure, send us the details and we will point you to a compatible option.
