NTN 2315 Self Aligning Ball Bearings

The NTN 2315 is a self-aligning ball bearing designed for electrician tool applications where shaft misalignment or mounting inaccuracies occur. It suits maintenance professionals who need reliable rotation under moderate radial and axial loads in power tool assemblies.

Thermals noise and power draw

Self-aligning ball bearings generate minimal friction heat during normal operation and run quietly when properly lubricated. Power draw is negligible as the component has no electrical consumption and simply reduces mechanical resistance in the drivetrain.

Questions about this item

How do I install the NTN 2315 self aligning ball bearing with its 75 mm bore onto the shaft without damaging the inner ring?

Press the bearing onto the shaft using a sleeve that contacts only the inner ring face, applying even pressure until the 75 mm bore seats fully against the shaft shoulder; never strike the outer ring or cage.

When should I plan to replace the NTN 2315 bearing given its 160 mm outer diameter and 55 mm width in continuous operation?

Replace the bearing when vibration or temperature monitoring shows a sustained rise, or at the relubrication interval limit for the 160 mm OD and 55 mm wide unit; inspect seals and raceways at each scheduled downtime.
