Description

This is a 6-inch brass carbon brush holder — a box-type brush holder with an overall length of approximately 6" (152 mm) between the brush box and the mounting stud, machined from brass with a copper-alloy box and steel/bronze stud. It is used on DC motor and generator commutators, slip-ring machines, and traction-motor brush systems (GE 752-class, EMD D-class and oilfield-drilling DC motors commonly use this holder family as aftermarket replacements). The holder provides the brush box, lead slot and terminal interface; the spring and wear device are normally separate items. Because fitment is machine-specific, verify the brush box (T × W), stud diameter and length, spring type and mounting against the original holder before ordering.

Features & benefits:

Brass / copper-alloy construction — corrosion-resistant, high-conductivity current path
~6" (152 mm) overall length for long-reach brush positions
Box-type design — accepts standard DC-motor brushes with flexible leads and terminal eyes
Stud-mounted — fits existing brush-holder studs/risers on motor-repair rebuilds
Suitable for GE 752-class, EMD D-class and general DC/slip-ring machines (verify per machine)
Quality-checked before dispatch; confirm brush box and stud with supplier
