Product Description

The NTN 4T-JHM318410 is a cup (outer ring) for a single-row tapered roller bearing. This cup is designed to be used with a corresponding cone to form a complete tapered roller bearing. The conical raceways on the inner and outer rings, along with tapered rollers, allow the bearing to handle both radial and axial forces in one direction.

Tapered roller bearings minimize sliding between raceways and rollers, reducing wear. They require a minimum load for proper operation. Because the cup and cone are separable, installation is straightforward, and axial clearance or preload can be adjusted during assembly.

For best performance, always pair this cup with a matching cone from the same manufacturer (NTN) to ensure compatibility in terms of internal profiles, materials, and tolerances.
