Description

This General Electric 2444731 carbon brush is a direct replacement slip-ring brush for GE brushed machines, listed in the GE & GE Amplidyne replacement brush reference (Figure 40A). The flat-top wafer carries a top-mounted insulated lead — the typical configuration for slip-ring brush boxes. The electrographite material (Morgan grade D / "Gray E") provides low electrical loss, medium contact drop, and stable, even film formation on slip-ring surfaces.

Features & benefits:

OEM-matched dimensions — 0.625" × 1.500" × 2.250" (15.9 × 38.1 × 57.2 mm) wafer, drop-in fit for GE slip-ring holders.
Electrographite material, Morgan grade D — low electrical loss, medium contact drop, low-to-medium friction, suitable for higher peripheral speeds.
5.750" insulated top lead with U-0.281" terminal — fatigue-resistant braided lead with U-lug for secure bolted connection.
Flat-top, top-lead design — standard Figure 40A slip-ring brush configuration.
Cross-referenced part numbers — GE 2444731, Morgan AM&T/National 2444731.
Quality-inspected before dispatch: dimensional check, lead crimp integrity, and surface condition per batch.
