Insert Bearings

Set screw type

NTN's unique ball-point set screws for select bearing units reliably lock the bearing units to the shaft even when they are subjected to vibration or impact loads.

Adapter type

The adapter type bearing unit can be reliably secured to the shaft even when it is subjected to impact loads and vibrations.
Under any operating conditions, this bearing unit can be used on a straight shaft whose fit grade is as poor as h9. Remember, however, this bearing unit must not be used on a shaft that is subjected to great axial load.

Eccentric collar type

When installing the eccentric collar type bearing unit, tighten the eccentric collar by turning it in the shaft rotating direction to secure the shaft to the inner ring. As a result, the shaft is reliably coupled with the inner ring and virtually no deformation occurs to the inner ring of the bearing. However, this bearing unit is not recommended for the machines which can run forward and backward, since the eccentric collar can loosen.
