The cone from TIMKEN's LM series is the inner race of a separable tapered roller bearing. It comes with the cage and rollers already assembled and sits on the shaft. A matching cup, or outer race, completes the bearing. The LM family uses inch dimensions and handles radial and axial loads together in demanding service.
Reading the LM code helps you identify the right part. The letters mark the series; the digits that follow encode size and variant. Each cone reference is distinct, and the TS suffix points to the cup series that pairs with it. Always order by the full code and keep the cone-cup combination intact.
These cones appear in gearboxes, transmission cases, axle assemblies on road machinery, earthmoving equipment, conveyors, mills, presses and farm machinery. They suit arrangements where radial and axial forces act at once and some misalignment is present. Because the series uses inch dimensions, it is common on machines built in the US or Europe.
When selecting a cone, begin with the complete code and the cup it matches. Confirm shaft diameter, width and the load the position must carry. At installation, pay attention to raceway alignment, axial clearance and lubrication; a proper grease or oil film supports bearing life. Effective sealing keeps contaminants out, which matters in dusty or wet conditions.
Tapered roller bearings interchange across brands by dimensional and designation equivalence, not by internal code. A replacement must share the same diameter, width and contact angle. If you need an alternative, we can point you to a compatible reference or quote a special if required. The LM series includes many references, and substitutions between manufacturers are common.
Send the cone or cup code by WhatsApp or email and we will quote it promptly. Ask about the associated cup or the complete assembly if you prefer. We know LM series applications and can help you resolve a replacement.

Frequently asked questions
- What is the difference between the cone and the cup of a tapered bearing?
- The cone is the inner race with rollers and cage, mounted on the shaft. The cup is the outer race, fitted in the housing. Together they form the complete bearing, so order both with their correct codes.
- How do I know which TIMKEN LM series cone my equipment needs?
- Read the code engraved on the cone or cup. With that data, we quote the exact reference. If the code is missing, send a photo and the shaft and housing dimensions by WhatsApp.
- Do you supply TIMKEN LM series bearings in the US and Latin America?
- Yes, MR Industrial Accessories serves customers across the United States and in several Latin American countries. Send the cone or cup code on WhatsApp or by email and we will reply promptly.
