LM SERIES | INCH TAPERED ROLLER BEARINGS

Bore d 17–197 mmDynamic load up to 195,000 NSingle row, separable cone and cupInterchangeable with SKF / FAG / NSK / TimkenMOQ 100 pcs

Series Overview

The LM series are inch-dimensioned, single-row tapered roller bearings designed to carry simultaneous radial and axial loads. The tapered geometry of the raceways converges at a common apex, giving the series its characteristic thrust capacity alongside high radial load performance.

The series spans bore diameters from 17 mm (LM11749) to 197 mm (LM540049), covering the most common inch tapered roller sizes used in agricultural machinery, industrial gearboxes and automotive drivetrains. Key models include LM104949 (50.8 mm bore), LM501349 (41.3 mm), LM603049 (45.2 mm) and the large-bore LL225749 (127 mm).

Supplied by GBC as matched cone-and-cup assemblies, interchangeable with SKF, FAG, NSK and Timken equivalents. MOQ 100 pieces.

Key Design Features

Combined radial and axial load capacity

Tapered raceway geometry handles both radial load and one-directional axial thrust simultaneously.

Separable cone and cup

Cone (inner ring assembly) and cup (outer ring) can be installed independently, simplifying assembly and allowing individual replacement.

Wide bore range in one series

Coverage from d 17 mm to d 197 mm within a single series prefix.

Direct interchange with major brands

Dimensionally equivalent to SKF, FAG, NSK and Timken LM series. Drop-in replacement.
