Product Description

The NTN 4T-HM804848/HM804810 is a single-row tapered roller bearing combining a cone (HM804848) and a cup (HM804810).
Its design features tapered rollers between conical raceways, allowing it to handle combined radial and axial loads in one direction.
The steeper the contact angle, the greater the axial load capacity.

This bearing is easy to assemble and disassemble, as the cone and cup are separable.
The cone unit consists of the inner ring, cage, and roller set, while the cup forms the outer ring.
Single-row tapered roller bearings have an open design, and when axial loads act in both directions, they are typically mounted in mirror-image arrangements.
Paired sets can also be installed in X, O, or tandem configurations depending on the application’s load direction.

The 4T-HM804848/HM804810 NTN is widely used in automotive wheel hubs, transmissions, and heavy-duty industrial machinery where high load capacity and precise alignment are essential.
