Collector-grade shaft grounding ring

This Aegis SGR-1.125-1A4-UK shaft grounding ring is a new collectible item listed under sports memorabilia. It is intended for enthusiasts who preserve industrial components rather than install them. The transparent aluminium ring represents a specific piece of power-transmission history.

Bolt-through split-ring design

The split construction allows the ring to clamp around a 1.125 in shaft without disassembly. Conductive epoxy and bolt-through mounting provide the electrical path that diverts VFD-induced currents away from motor bearings. Compatible motor frames include 182T and 184T in NEMA sizing.

Upgrade from solid-ring or non-conductive mounts

Collectors or maintainers replacing a solid-ring grounding device gain the split-ring convenience. The jump is worth it when a motor frame 182 or 184 requires VFD protection but the shaft cannot be removed for a solid ring installation.

Questions about this item

What is the largest NEMA motor frame the Aegis SGR-1.125-1A4-UK shaft grounding ring fits?

The ring is compatible with NEMA motor frames 182T and 184T, so frame 184T is the largest supported size.

How much heat does the Aegis SGR-1.125-1A4-UK shaft grounding ring generate during continuous operation?

The grounding ring is a passive conductive component with no moving parts, so it produces no measurable heat while diverting VFD shaft currents.

Which mounting hardware must the buyer already have to install the Aegis SGR-1.125-1A4-UK shaft grounding ring?

The ring uses a bolt-through mount with conductive epoxy, so you need matching bolts and the epoxy adhesive before installation.
