Solid Ring Installation Guide

Refer to the AEGIS® Handbook for Best Practices.

  1. Motor must be grounded to common earth ground with drive according to applicable standards.
  2. Shaft must be clean & free of any coatings, paint, or other non-conductive material.
  3. AEGIS® SGR should not operate over a keyway. If SGR will operate over a keyway, fill keyway with a fast-curing epoxy putty in the area of contact.
  4. Install the SGR so that the aluminum brush holder maintains an even clearance around the shaft. Conductive MicroFibers™ must be in contact with conductive metal surface of the shaft.
  5. English Mounting Hardware:
    1. Drill (2 to 4) holes using a #36 drill (number of holes depends on SGR size and motor end bell)
    2. Depth of hole should be 1/4" CAUTION: DO NOT DRILL INTO BEARING
    3. Tap each hole with a #6-32 tap.
  6. Metric Mounting Hardware:
    1. Drill (2 to 4) holes using a 2.5mm drill
    2. Depth of hole should be 6mm CAUTION DO NOT DRILL INTO BEARING
    3. Tap each hole with a M3 tap
  7. To improve the conductivity of the steel shaft surface we recommend coating the shaft, where the fibers will contact the shaft, with our AEGIS® Colloidal Shaft Coating PN CS015. See CS015 instructions for details.
  8. Hold the SGR in place by fastening clamps to motor end bracket using screws and washers provided. Use minimum of 2 mounting clamps, supplied with SGR, to ensure proper ground connection. Do not use Loctite© or any other non-conductive material to secure the screws.
  9. After installation, test for conductive path to ground using Ohm meter. One probe is on metal frame of SGR and one probe on motor frame. CAUTION: SGR IS NOT A GROUND FAULT PROTECTION DEVICE.
  10. In occasions where SGR is exposed to excessive debris, additional protection of the SGR fibers may be necessary.

 

Custom Brackets

In some cases, the clamp on mounting option cannot be used because the motor end bracket has an irregular shape or shaft step. In these cases, we recommend the AEGIS® uKIT with Universal Mounting Brackets.

Alternately, the Mounting Plate is another option and can be used with the AEGIS® SGR Solid Ring (-1 design) and the AEGIS® SGR Split Ring (-1A4 design).

The aluminum plate with spacers is mounted to the end bell of the motor and avoids irregular shaped end bells and shaft steps. Normally the AEGIS® ring will be on the "u" dimension of the shaft.

Installation Instructions

The plate is tapped for 6-32 screws. The hardware brackets and screws supplied with the -1 and -1A4 rings are used to attach the ring to the aluminum plate.

To select the correct Mounting Plate, first choose the AEGIS® SGR Grounding Ring. Must be a -1 (solid ring) or -1A4 (split ring) . Be sure to measure the shaft where the fibers will make contact. Then based on the AEGIS® ring's outside diameter (OD), select the matching plate from the list below.
