The TIMKEN JM series tapered roller cup is the outer race of a tapered roller bearing assembly. It is installed in the housing and works together with the cone, which carries the rollers and cage, to handle radial and axial loads at the same time. Typical uses include gearboxes, machine shafts and other industrial equipment that demands rigidity and load capacity. MR Industrial Accessories supplies this cup and can help you confirm the correct pair for your application.

The JM prefix identifies a family of medium-section cups. Part numbers such as JM205110, JM207010 or JM511910 combine that prefix with a number that defines the cup's size and geometry. Each reference has its own outside diameter, width and raceway angle. Because cup and cone are matched, selection should begin with the cone you already have or with the complete assembly number.

In US plants and workshops, these cups appear in gear reducers, machine tool spindles, conveyor shafts, and in mining, grinding and agricultural equipment. Tapered bearings let you set clearance and take combined loads, and since the cup is removable, you can replace the outer race without disturbing the housing.

Before mounting, make sure the housing bore is clean and free of burrs, and that the cup sits fully against the shoulder. Choose lubrication according to speed and environment: grease for low speed or oil in circulating systems. Effective sealing keeps contaminants out and lubricant in. Cup-to-cone alignment matters, because misalignment speeds up wear and creates noise. Set axial clearance to suit the application.

Cups from different manufacturers can be interchanged when the standardized dimensions and raceway angle match. A similar part number is not enough: compare outside diameter, width and fillet radius. Cross-references exist, but tolerances vary by maker. For a replacement, send the full part number and housing dimensions so we can identify a compatible option.

MR Industrial Accessories supplies the TIMKEN brand. To request a JM series cup, send the part number or model by WhatsApp or email. We will quote it promptly and help you get the mounting right. If you have the assembly dimensions, we can also assist in identifying the cone-cup pair.
