Key Features:

Single-row tapered roller design (cup and cone) for easy assembly/disassembly — the HM88644/HM88610 bearing’s separable cup and cone allow quick mounting, inspection, and replacement without disturbing the mating component.

Conical raceways with tapered rollers for combined radial and axial load support (axial in one direction) — the tapered geometry provides stable rolling contact that handles both heavy radial loads and thrust loads along one direction.

High radial and axial load capacity; increased contact angle raises axial capacity — engineered contact angles and roller profiles deliver higher load ratings and better performance under combined loading.

Open internal design; requires pairing (mirror-image) for full axial support — the open design improves cooling and reduces friction but needs a matched opposite bearing to handle bidirectional axial forces.
