  • 150 mm outer diameter supports heavy radial loads
  • 51 mm width provides extended bearing surface

NTN 2314K Self Aligning Ball Bearings 70x150x51mm

The NTN 2314K self aligning ball bearing suits electricians and maintenance teams who need to accommodate shaft misalignment in motor and pump assemblies. Its spherical outer race allows angular movement without imposing edge loads on the rolling elements. Buyers who require a cylindrical bore or a different bore diameter will need an alternative bearing.

Normal use thermals noise and power draw

Self aligning ball bearings generate minimal friction when correctly lubricated and mounted within their load ratings. Operating temperature rises stay modest in typical electric motor service and noise levels remain low at standard speeds. The component itself draws no electrical power; it transmits mechanical load between shaft and housing.

Questions about this item

How do I press the NTN 2314K bearing onto a 70 mm shaft without damaging the self-aligning races?

Use a sleeve that contacts only the inner ring and apply even force until the 70 mm bore seats fully; never strike the outer ring or cages.

When should I plan to replace the NTN 2314K bearing in continuous electrician-tool service?

Replace when vibration or noise increases beyond normal levels, indicating race wear or cage fatigue inside the 70x150x51 mm envelope.
