Installation using Screws

• Drill (3 or 4) holes using a #36 drill. Avoid drilling into bearing.

• Depth of hole should be 1/4”

• Tap each hole with a #6-32 tap

• Install the uKIT and secure to the motor with the hardware provided. The bolts provide the path to ground. Do not use Loctite© or any other non-conductive material to secure the screws.

Installation using Conductive Epoxy (EP2400)

• Remove paint on the motor end bell where the AEGIS® uKIT brackets will be attached. These areas must be clean and free of any coatings, paint, or other nonconductive material.

• Prepare conductive epoxy per package directions.

• Apply the epoxy to the mounting brackets.

• Install the uKIT. Hold the uKIT in place until epoxy is firmly holding. Allow epoxy to cure for 4 hours at or above 75°F. For quickest curing time, use a heat gun to heat epoxy to 150-250° for 10 minutes then allow to cool.

Preparation • Shaft must be clean

and free of any paint, coatings, or other nonconductive material.

• AEGIS® Rings should not operate over a keyway. Fill keyway with a fast-curing epoxy putty (such as Devcon epoxy putty) in the area of contact.

• To increase conductivity of the shaft, apply AEGIS® Colloidal Silver Shaft Coating to the area where the AEGIS® microfibers will be in contact with the motor shaft. Apply all around the shaft.

• Select bracket size based on the clearance needed from the end bell/slinger/shaft shoulder. For solid ring, use either a 3-hole or 4-hole bracket pattern. For split ring use 4 brackets. Attach brackets to the AEGIS® ring using the 5-40 x 3/8” flat head screws.

• Install the AEGIS® uKIT so that the aluminum ring maintains an even clearance around the shaft. Conductive microfibers should be in contact with the conductive metal surface of the shaft. Mark bracket locations.

AEGIS® Electrical Bearing Damage ProtectionAEGIS® uKITs combine an AEGIS® Shaft Grounding Ring and universal mounting brackets, allowing external mounting of the ring on any motor — even those with shaft shoulders, slingers, seals, or other end bell protrusions. AEGIS® uKITs include:

• AEGIS® Rings sized for NEMA frame motor shaft diameters (NEMA “u” dimension) from 56 to 449T

• Solid and split ring designs • Mounting brackets and hardware for installation of the AEGIS®

Ring on virtually any end bell • Brackets can be mounted with screws or AEGIS® Conductive

Epoxy Adhesive (Epoxy EP2400 sold separately)

SolutionAEGIS® Bearing Protection Rings protect motors by channeling harmful VFD-induced shaft voltages away from bearings and safely to ground, preventing bearing failure and costly unplanned downtime.

ProblemWithout AEGIS® Bearing Protection, induced shaft voltages can cause bearing pitting, frosting, and fluting, dramatically reduce the effectiveness of lubrication, and lead to catastrophic bearing failure.

• Install AEGIS® Bearing Protection Ring – either internally or externally – on drive end or the non-drive end of motor. Use AEGIS® Colloidal Silver Shaft Coating (PN CS015) on motor shaft where fibers touch.

Product recommendation: AEGIS® SGR

• Drive End: Install AEGIS® Bearing Protection Ring - Internally on the back of the bearing cap or externally on the motor end bracket. Use AEGIS® Colloidal Silver Shaft Coating on motor shaft.

• Non-Drive End: Isolate bearing housing with insulated sleeve or coating or use insulated ceramic or hybrid bearing to disrupt circulating currents.
