The Robert Bosch Tool Corp 1604336048 is an original equipment manufacturer (OEM) brush holder sub-assembly designed for industrial-grade commutated electric motors. It serves as the physical housing and electrical conduit that maintains the position of the carbon brush against the spinning armature commutator in high-capacity power tools.
Features
Integrated Spring Module: Pre-equipped with a torsion spring to maintain consistent mechanical force throughout the brush wear cycle.
Arc-Reduction Configuration: Precision-machined inner brass guide minimizes brush vibration and chatter to reduce electrical arcing.
Thermal Protection: Engineered to withstand operational temperatures exceeding 150°C without structural degradation.
Vibration Resistance: Molded locking lugs and anchoring screw points ensure flush alignment with tool housing to damp high-frequency vibrations.
Dielectric Strength: High-performance polymer housing prevents current leakage to the tool casing.
Low-Friction Guide Path: Brass/copper alloy insert provides a precision guide path resistant to corrosive pitting.
