Beaver Electrical Machinery is Canada's only trained installer for AEGIS® bearing protection rings. When Beaver installs an AEGIS® protection ring, it is granted additional manufacturer's warranty length.
Without bearing protection, shaft voltages can cause fluting damage.

We offer the following services to help prevent electrical bearing damage:
- Bearing Cutting and Inspection
- Shaft voltage testing
- External AEGIS® Installation
- Internal AEGIS® Installation
Your Bearings Can Fail from VFD-Induced Shaft Currents VFDs allow large energy savings and precise control. But they also generate electric voltages on motor shafts. These shaft voltages can discharge through the bearings, causing pitting, fluting, and eventual bearing failure.
Protect Your Bearings AEGIS® Shaft Grounding Rings are the leading bearing protection technology. They protect bearings by giving shaft voltages a "path of least resistance" to ground, so the shaft discharges through the ring, not the bearing. Unlike other shaft grounding products, AEGIS® rings are long-lived and maintenance-free, and can be installed inside or outside of the motor.
