The 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. Kits also include a sturdy aluminum mounting
plate and all mounting hardware. The SGR Bearing Protection Ring
dramatically extends motor life and prevents bearing noise, downtime
and costly motor repairs/replacements, says the vendor. Ordered by
motor frame size, standard-size kits fit NEMA-frame motors with shaft
diameters from 0.625-in. to 3.375-in. and IEC-frame motors with shaft
diameters from 19mm to 95mm. Electro Static Technologywww.est-aegis.com866.738.1857
