The NSK JM series tapered roller cup is the outer raceway that presses into the housing. It pairs with a cone, the inner assembly of raceway, rollers and cage, to handle combined radial and axial loads. You will find this cup in gearboxes, machine shafts and power transmission systems where alignment and load capacity matter.

The JM prefix marks a series of tapered roller cups built to standardized dimensions. The number that follows sets the size: JM 734410, JM 738210 and JM 822010 are three examples. When you order, use the full part number from the drawing or nameplate.

These cups show up in food processing, metallurgy, mining and agriculture equipment. Typical locations include gearboxes, drive shafts, conveyor rollers, machine tools and material handling machinery. Their job is to carry combined loads and hold axial clearance steady so the shaft turns accurately under thrust.

Selection starts with the housing bore. The cup outer diameter and raceway width must match the housing, while the cone seats on the shaft. Lubricate with the specified grease or oil and check cone-to-cup alignment to avoid premature wear. Adjust axial clearance by the usual method if the assembly calls for it.

Cups from different brands can interchange when the standardized dimensions and raceway angle agree. A similar part number is not enough: compare outer diameter, width and raceway radius. If you have an unidentified cup or a number from another brand, send those details and we will point you to a compatible equivalent.
