NTN 1217 Self Aligning Ball Bearing

The NTN 1217 is a self aligning ball bearing sized 85x150x28mm and supplied in a red box as a single pack. It is intended for electricians and maintenance technicians who need a replacement bearing that accommodates shaft misalignment in motor or gear assemblies.

Upgrade from fixed geometry bearings

This bearing replaces rigid deep groove types where shaft deflection or mounting error causes premature wear. The self aligning design compensates for angular misalignment, making the swap worthwhile when vibration or uneven loading has shortened the life of the original component.

Behaviour under sustained load

The spherical outer raceway allows continuous realignment while the bearing runs, so contact stress stays distributed during extended duty cycles. Heat buildup remains stable because rolling elements track consistently rather than skidding when the shaft flexes under load.

Questions about this item

What shaft and housing diameters does the 85x150x28mm bearing fit?

The bearing has an 85 mm bore for the shaft and a 150 mm outside diameter for the housing seat.

Which step is often missed when pressing the 1217 bearing onto the shaft?

Apply force only to the inner ring using a sleeve that matches the 85 mm bore; pressing the outer ring damages the self-aligning raceway.

When should the NTN 1217 bearing be replaced?

Replace it when vibration, noise or excessive radial play appears, indicating raceway wear or cage fatigue.
