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.

Questions about this item
What shaft diameter fits the 85 mm bore of the 6317 bearing?
The bearing has an 85 mm inner diameter so it mounts on an 85 mm shaft.
Which way round should the 6317 deep groove bearing be pressed into the 180 mm housing?
Press the outer ring evenly into the 180 mm housing bore; the bearing is non-directional so either face can lead.
