Precision Parts LM501349 Tapered Roller Bearing Cone Bore Bearings & Seals - 1.625

The Precision Parts LM501349 is a tapered roller bearing cone (inner ring assembly) from the LM501300 series. Designed to handle both radial and axial loads simultaneously, this single-row tapered roller bearing cone is a widely used component in automotive wheel hubs, trailer axles, agricultural equipment, and a variety of industrial machinery applications.

The cone is paired with a compatible cup (race) — most commonly the LM501310 or LM501314 — to form a complete tapered roller bearing assembly. Its tapered internal geometry allows for precise adjustment of operating clearance or preload, ensuring smooth, reliable rotation under load.
