Products NKE Bearings

---

• Bearing units consist of a housing and an insert bearing. 
• Housing cast iron or pressed steel

To Product

• Tough industrial applications require special bearings.
• NKE hybrid bearings are consist of steel rings and bearing silicon nitride Si3N4 rolling elements.

To Product

• Optimum protection against bearing damage caused by the passage of currents.
• NKE electrically insulated rolling bearings reliably prevent current discharge.
• NKE provides bearings with oxide ceramic insulating layers on the bearing ring. 

To Product

Inch sized (imperial) bearings are still used in many applications and are manufactured in inch sizes, to match British and American machinery.
