FAG KJM-XL tapered roller bearings handle radial and axial forces in a single direction. The tapered rollers run on inclined raceways, so contact is linear and the load spreads over a wider area. That makes them a common choice where both load types appear at once and capacity matters, as in transmissions, wheel axles and general industrial equipment. MR Industrial Accessories supplies this line to maintenance and purchasing teams in the United States and Latin America.

A complete bearing is made of two matched parts: the cone and the cup. In this series the cones are KJM714249 and KJM738249, and the cups are JM714210 and JM738210. The K prefix points to a special mounting or bore design, JM is the dimension series, and XL marks the current FAG generation. Assemblies are ordered as pairs, for example KJM714249-JM714210-XL or KJM738249-JM738210-XL.

You will find these bearings in gearboxes, drive shafts, mining equipment, mills, presses, agricultural machinery, conveyor rollers and machine tool spindles. Helical gears and wheel axles are typical cases: the bearing takes radial and axial load at the same time, which is exactly what the inclined raceway layout is meant for. They suit both replacement work and new builds.

When selecting, look at radial load, axial load, speed and the operating environment. During mounting, set the internal clearance to suit the application: tighter clearance adds rigidity but also raises temperature. Use the correct grease or oil, keep the cone and cup precisely aligned, and fit seals to block contaminants and hold lubricant in place.

FAG tapered roller bearings can be swapped with other brands that share the same dimensions and designation, such as SKF, Timken or NSK, provided tolerances and clearance match. Keep the cone and cup from the same maker, or from makers known to be compatible. Direct interchange is not automatic, so check equivalents before you replace.
