Mechanic Falls, Maine-based Electro Static Technology has introduced two new AEGIS SGR split-ring bearing protection kits – one for NEMA motors and one for IEC motors. Developed for easy field installation without disassembly of coupled equipment, these new split-ring kits are designed to provide clearance for shaft shoulders, slingers and other end-bell protrusions, while protecting bearings from electrical damage caused by circulating or shaft currents.
Kits include the new split-ring version of the SGR bearing protection ring. The ring prevents bearing damage by safely channeling shaft currents to ground. Its conductive microfibers provide the path of least resistance to the motor frame. Kits also include an aluminum mounting plate and all mounting hardware.
The SGR bearing protection ring extends motor life and prevents bearing noise, downtime and costly motor repairs/replacements, according to the company.
Because the ring comes in halves and the mounting plate is U-shaped to fit around the motor shaft, both can be installed without disconnecting the motor from coupled equipment.
