Product Description

The LM67049A NTN is the cone portion of a single-row tapered roller bearing. This detachable component contains the bearing’s inner ring and rollers. When paired with a separately available cup (outer ring), these parts form a complete tapered roller bearing. The conical shape of the inner and outer rings, along with the tapered rollers, allows the bearing to support both radial and axial loads in one direction.

Due to their geometry, tapered roller bearings minimize sliding between the raceways and rollers, which helps reduce component wear. However, a minimum load is needed for proper operation. Since the cone and cup are separate pieces, assembly is straightforward, and you can easily adjust end play or preload by moving the components axially during installation.

For dependable performance, it’s best to replace both cone and cup simultaneously, and to use components from the same manufacturer. This practice helps avoid issues related to differences in internal profiles, materials, or tolerances. Always pair the LM67049A NTN with a compatible cup from the same brand.
