If you see early bearing wear or hear strange noises, act fast. Talk to your technician or supplier about upgrading to insulated bearings. Match the size and type to your motor’s needs. Do not delay ...

Electrically insulated bearings protect against bearing damage caused by electrocorrosion — the passage of electrical current.

This can drive a current down the shaft, to the bearings, through the frame, and back again through the bearings, as shown in Fig. 1 above. The resulting current isn't localized within the bearings.

FAG insulated bearings FAG Insulated Bearings are a range of bearings distributed by eMotors Direct that are specially designed to prevent shaft currents from passing through, preventing bearing ...

Protected by an AEGIS SGR bearing protection ring, the race on the right is undamaged. Figure 4. For motors over 100 hp, where both circulating currents and common mode voltages could cause bearing ...

The SQ77 Series of rolling bearings feature built-in electrical insulation for protection against current discharge and the resulting electrical corrosion ...
