PRO Series Rings Have 6 Rows of Conductive Microfibers for Maximum Bearing Protection

Shaft protection ring

AEGIS® PRO Series Rings protect large
medium-voltage AC motors (as well as
large low-voltage AC and DC motors) from
VFD-induced bearing damage. The AEGIS®
PROSL (shown above) and all AEGIS® PRO
Series Rings have 6 rows of conductive
microfibers that provide the high current-
carrying capacity needed for these large
motors.

New AEGIS® PRO Series Rings are specially designed to protect medium-voltage motors, generators, and turbines as well as large low-voltage AC motors (over 500 HP) and large DC motors (over 350 HP) from damaging VFD-induced shaft voltages and bearing currents.

Available in solid- and split-ring versions for shaft diameters from 2″ (50mm) to 31.5″ (800mm), these rings have 6 rows of conductive microfibers that completely encircle the motor shaft, providing many millions of contact points that channel harmful shaft voltages away from motor bearings and safely to ground.

Solid AEGIS® PRO Rings are ideal for installation on new motors before they are put into service or in-service motors when they are repaired.  Split PRO Rings are designed for fast, easy field installation around the shaft of a coupled motor.

The new product line includes:

AEGIS® PROSL: Available in solid- and split-ring versions for shafts of 2″ (50mm) to 16.6″ (400mm) in diameter.  It has a maximum OAL of 0.650″ (15.88mm).

AEGIS® PROSLR: Specially designed for severe-duty environments, the AEGIS® PROSLR is also available in solid- or split-ring versions for shafts of 2″ (50mm) to 16.6″ (400mm).  To ensure maximum operating reliability in severe environments, it includes an O-ring barrier installed on its front and back faces to protect from the ingress of contamination.  It has a maximum OAL of 0.750″ (19.05mm).

AEGIS® PROMAX: Designed to protect the largest motors and generators, the AEGIS® PROMAX is a split ring for shafts of 16.6″ (400mm) to 31.5″ (800mm) in diameter.  With a maximum OAL of 1.545″ (39.24mm), each AEGIS® PRO MAX Ring is custom designed for the specific application.

AEGIS® PROMR: Combines an AEGIS® PROSL bearing protection ring with an AEGIS® SGR monitoring ring (separated by an insulated phenolic spacer) in a single assembly.  Available in solid- and split-ring versions, it provides bearing protection and real-time monitoring capability for remote or hard-to-access motors.  Available for shafts of 2″ (50mm) to 16.6″ (400mm), it has a maximum OAL of 1.312″ (33.32mm).

Universal Mounting Brackets: Designed to accommodate shaft shoulders, slingers, or other motor face protrusions, Universal Mounting Bracket Kits speed and simplify mounting of all AEGIS® PRO Series Rings.

AEGIS® PRO Series Rings are designed to protect larger motors in processes and applications where the cost of bearing damage, motor repairs, and downtime can be staggering.  Don’t risk motor damage and the high cost of lost production.  Protect your large motors with AEGIS® PRO Series Rings!
