The TIMKEN TSF series tapered roller cup is the outer ring of a separable tapered roller bearing. It is the raceway the cones run on, press-fitted into the housing, and it sets the contact geometry of the assembly. These cups are used where equipment carries combined radial and axial loads, and they are supplied by part number for replacement work or for building new machines.

Reading the part number helps you order the right cup. The letters JL at the start point to the dimensional series and raceway angle. The digits that follow give the assembly size. The -B suffix flags a construction variant inside that series, such as a different width or fillet radius. You can see the pattern in JL730612-B and JL848815-B: series letters, size number, suffix. The TSF series covers single-row tapered roller cups, each meant to be mounted with its matching cone.

Typical applications include reducers, transmission boxes, wheel shafts, earthmoving equipment, mills and conveyors. Maintenance teams also find them in aggregate plants, cement plants and continuous process lines. Because the cup is a wear part, replacement is handled by part number: identify the cup, order it, and restore the full bearing without changing the housing.

Selection depends on keeping the cone-cup pair together. Do not mix parts from different series, even when the outer diameter appears to match. Mounting should be done with a press or controlled impact tools, never by striking the raceway directly. Lubrication and sealing decide how long the assembly lasts, so in dusty or wet areas lip seals and high-consistency grease are worth considering. Shaft alignment and axial clearance are set according to the equipment, not to the isolated part.

TIMKEN is a brand that MR supplies. For a quote, send the complete cup part number and, if you have it, the cone number that goes with it. A photo of the part or caliper measurements also help. In several cases there are compatible alternatives from other tapered roller bearing brands, and we point them out when they apply.
