For equipment that sees both radial and axial forces at the same time, FAG tapered roller bearings are a common choice. Their geometry uses linear contact between rollers and raceways, which suits arrangements that need stiffness and running accuracy. Typical places you will find them include gearboxes, reducers, wheel hubs and general industrial machinery. MR Industrial Accessories LLC supplies this line as one of the brands we carry.

A complete bearing is made up of two matched parts: the cone and the cup. Codes such as KLM48548-A-LM48510 follow that logic. The KLM prefix points to a tapered roller design, with dimensions given in metric or inch units depending on the standard. The -A suffix marks a design variant, and the second code identifies the cup. The pairs KLM67049-A-LM67010 and KLM503349-A-LM503310 show the same pattern. Once you understand how the two codes fit together, picking a replacement becomes much easier.

These bearings appear in automotive, metallurgy, food processing and mining operations. You will often see them in gearboxes, rear axles, machine tool spindles and conveying equipment, as well as in kiln rollers, presses and lifting systems. Because they handle combined loads, they work well on shafts where radial and axial forces act at the same time.

When selecting a tapered roller bearing, look at the radial and axial load, the rotational speed and the operating environment. Installation calls for careful alignment and correct adjustment of axial clearance, usually set with shims or nuts. Grease or oil can be used for lubrication, and the sealing method depends on how much contamination is present. Always check the interference fit on the shaft and in the housing to avoid premature wear.

Interchangeability between brands is possible when dimensions and contact angle match, since tapered roller bearings are made to international standards. For a replacement, compare the full code, cone and cup together, and confirm the tolerances. FAG covers a broad range, and MR Industrial Accessories LLC can help you find the right option for your equipment.
