Baldor Electric Company WS33RK5004 Rocker Arm

Baldor WS33RK5004 Rocker Arm is Baldor’s carbon-brush rocker-arm assembly used in Baldor Reliance motors that employ a brush-gear arrangement. Listed in Baldor catalogs as 33RK5004SP Rocker Arm Assembly, this component serves as the functional link in the carbon-brush mechanism, helping position and maintain contact between the carbon brushes and the commutator for consistent electrical transfer and predictable brush wear. The part is designed to be replaced as a single rocker-arm assembly in applicable Baldor motor configurations, supporting reliable maintenance of the brush assembly and ongoing motor performance in industrial settings. Replacement is typically performed during motor overhauls or when brush contact becomes degraded, helping restore defined brush travel and contact pressure. The 33RK5004SP designation confirms its role as the standard rocker-arm assembly for this line, and Baldor catalogs list it as a dedicated spare for maintenance and repair operations.
