AEGIS® PRO Series High Current Bearing Protection Ring

PRO Series

Medium Voltage Motors, Generators and Turbines

The AEGIS® PRO Series design provides reliable shaft grounding for medium voltage applications, generators, and turbines to divert harmful shaft voltages to ground and extend bearing life. Install the AEGIS® PRO on the DE and insulate the bearing on the opposite end (NDE) for best results. Large motors and generators often have much higher induced shaft voltages and bearing currents. The six circumferential rows of conductive microfber provide the extra protection for these high current applications.

Generators may experience current surges which can cause electrical arcing in their bearings and equipment. The AEGIS® PRO Rings have a high current capable design and can discharge these currents.

PROSLR

AEGIS® PROSLR

Severe Duty motors are operated in general processing industry applications requiring protection from severe environmental operating conditions - often where there is debris, powder, dirt, liquids, lubricants or other contaminants which can collect around the shaft of the motor where the AEGIS® PRO Ring is installed. For these applications the AEGIS® PROSLR incorporates a pair of O-ring dust and debris barriers which prevent ingress of materials that could interfere with the contact of the conductive microfibers to the motor's shaft.

  • For shaft diameter 2.5" to 15.750" [63.5mm to 400mm]
  • OD = shaft diameter + 1.86" [47.24mm]
  • OAL = 0.650" (16.51mm) max assembled with FHCS
  • Flat head mounting screws included for bolt-on mounting.
    • English (4) 8-32 x 1" FHCS or
    • Metric (4) M4 x .7 x 25mm
  • Stock universal mounting brackets available; custom brackets available by request.
  • Supply shaft diameter in inches x.xxx (3 places) or metric x.xx (2 places) for best fit
  • Drawing Template (solid ring)
  • Drawing Template (split ring)

PROMAX

AEGIS® PROMAX

  • For shaft diameter 15.760" to 30" [401mm to 762mm]
  • OD = shaft diameter + 3.0" [76.2mm]
  • OAL = 1.875" (47.62mm) max assembled with SHCS

PROMR

AEGIS® PROMR

The NEW AEGIS® PROMR includes a "monitoring ring" combines the AEGIS PROSL with an additional isolated SGR ring that can be used as a monitoring device. The PROSL channels the voltages and currents safely to ground while the monitoring SGR ring measures voltage on the shaft and is not grounded. A phenolic plate between the 2 rings is used to isolate the monitoring ring.

  • For shaft diameter 2.5" to 15.750" [63.5mm to 400mm]
  • OD = shaft diameter + 1.86" [47.24mm]
  • OAL = 1.312" (33.2mm) assembled with mounting screws
  • Flat head mounting screws included for bolt-on mounting.
    • English (4) 8-32 x 1" FHCS or
    • Metric (4) M4 x .7 x 25mm
