FAQ What is the significance of the CG665 grade?CG665 is a Mersen material grade designation for a specific carbon-graphite composite. It is engineered for low friction, good load-carrying capacity, and excellent commutation, which helps reduce sparking and commutator wear in DC machines. How do I ensure this brush is the correct size for my motor?While the grade CG665 is critical for electrical performance, you must also match the brush’s physical dimensions (length, width, thickness) to your motor’s brush holder. Please measure your existing brush or holder carefully before purchasing. Can I use a different grade of carbon brush if CG665 is not available?It is strongly recommended to use the grade specified by the motor manufacturer. Using a different grade can lead to poor performance, excessive sparking, and accelerated wear of the commutator.
