Description

Brush Holder 1.25 X .75 X 2.25, Single is a single cavity, single leg brush holder assembly made to accommodate carbon brush dimension 1.25 inch × 0.75 inch × 2.25 inch. The holder body is manufactured from high-performance phenolic resin, offering excellent insulation, heat resistance and mechanical strength to withstand continuous vibration and temperature fluctuations in heavy industrial environments. Equipped with stainless steel constant force spring, it applies steady pressure on the carbon brush, minimizing electrical sparking and slowing down commutator surface abrasion. Copper alloy terminals ensure reliable electrical conductivity and reduce heat build-up under continuous load. Single leg mounting design provides simple, space-saving installation for DC motors and traction equipment. It is a direct replacement spare part for maintenance projects where the original brush holder or carbon brush with 1.25 x 0.75 x 2.25 inch size needs replacement. Made to match OEM dimensional requirements for industrial rotating machinery repair.
