Description

Traction Brush Holder .75 X 2.25 X 1.89 is a heavy-duty carbon brush holder assembly specially engineered for railway and locomotive traction motors, designed to accommodate carbon brush size 0.75” × 2.25” × 1.89”. The housing is made of high-performance phenolic resin, delivering excellent insulation, heat resistance and mechanical strength to survive extreme vibration, shock and temperature fluctuations typical in locomotive traction environments. Fitted with stainless steel constant force spring, it keeps uniform pressure on the traction carbon brush during variable speed operation, minimizing electrical sparking and protecting the commutator surface from premature wear. Copper alloy terminals provide stable electrical conductivity and low heat generation under high traction load. Bolt-on mounting enables convenient field replacement during locomotive maintenance overhaul. Manufactured to OEM dimensional specifications, it serves as a reliable spare part for traction motor repair for rail and heavy traction machinery.
