NTN Bearings 6317 Deep Groove Ball Bearing 85x180x41mm

NTN 6317 Deep Groove Ball Bearing

The NTN 6317 is a precision deep-groove ball bearing built for electricians and maintenance technicians who need reliable rolling-element performance in motor shafts, gearboxes or pump assemblies. Its 85 mm bore, 180 mm outside diameter and 41 mm width suit standard industrial housings where radial and moderate axial loads are present. The single-row design simplifies installation and keeps running friction low across a wide speed range.

Upgrade from worn or noisy bearings

Replace this unit when an existing 6317 shows increased vibration, heat or audible rumble that signals raceway fatigue or contamination damage. The jump is worth it when uptime matters more than the cost of a scheduled swap, especially in continuous-duty equipment where an unplanned stoppage outweighs the bearing price. It is not for applications needing sealed or shielded variants, higher load ratings, or non-standard dimensions.
