A TIMKEN LM series tapered roller bearing comes as two separate pieces: a cone and a cup. Their tapered raceways and rollers meet at a single point along the shaft axis. That design lets the bearing handle radial and axial forces at the same time, making it a common choice for gearboxes, wheel shafts, agricultural machinery and other industrial equipment where loads come from two directions.

The LM prefix groups bearings by dimension family. The digits that follow, plus any final letter, set the size and identify the cone or cup variant. For instance, in part number LM757049A, the A suffix points to a specific internal fit. Because cone and cup are ordered separately or together, always give the full part number so parts from another series are not mixed in.

You will find these bearings in gearboxes, seeders, harvesters, mills, conveyor belts, overhead cranes and material handling equipment. Machine tool spindles and rolling mill rolls also use them, since those applications combine radial and axial loads and demand a well-seated mounting.

When selecting a bearing, consider the radial load, the axial load, the rotation speed and the fit required on the shaft. Mounting is done with cone and cup apart: heat the cup to seat it in the housing, set axial clearance with shims or nuts, and apply grease or oil according to the equipment. Shaft-to-housing alignment matters so the rollers share the load evenly.

Interchange between brands works by series and by cone and cup dimensions, not by the commercial part number. The same size can carry different letters from one maker to another, and the suffix affects the fit or the contact angle. To replace a reference, send the old part number along with the shaft and housing dimensions, and we will point you to the compatible option.

For a TIMKEN LM series tapered roller bearing, message us on WhatsApp with the part number or model you need. We will quote it promptly and, when necessary, suggest a compatible alternative. Our own manufacturing covers split plummer block housings, ANSI chains and sheaves to complete the assembly.
