Electric Power Tool Spare Parts Carbon Brush 6.3 X 16 X 22 MM

Key Information Analysis:

1. Product Type: Carbon Brush for Electric Power Tool Spare Parts
   Made by pressing a mixture of graphite and a high proportion of copper powder (copper content is about 30%-50%), it has both excellent electrical conductivity and wear resistance. The high copper content formula enables it to withstand large current loads, making it suitable for high-frequency and high-intensity working scenarios of medium and high-power motors, reducing overheating or burning of the carbon brush caused by excessive current.
2. Compatibility Range:
   Based on the 6.3×16×22mm specification, it is suitable for brushed motors of various medium and high-power electric tools. Common applicable scenarios include:
   • Industrial-grade electric tools: such as heavy-duty angle grinders, large grinders, high-torque electric drills, industrial-grade reciprocating saws, etc.;
   • Professional equipment: some models of stone cutting machines, concrete vibrators, heavy-duty polishers, etc.
     The core of compatibility is that the size must completely match the motor's brush holder (with an error of ≤0.2mm). In particular, the width (16mm) and thickness (6.3mm) must strictly correspond; otherwise, it may cause unstable installation or poor contact, affecting the power output of the tool.
3. Size Specifications: 6.3×16×22 MM
   This size belongs to the medium-to-large carbon brush category. The length of 22mm allows for a longer service life, and it is suitable for motors with a power of 800-2000W. Dimensional accuracy is crucial for usage safety; if the error exceeds the allowable range, it may lead to insufficient contact area between the carbon brush and the commutator, causing excessive motor sparks, abnormal noise, or even equipment damage.
4. Functions and Roles:
   • Serves as the "core of current conduction" for medium and high-power motors, ensuring stable power output of the tool during high-load operations (such as cutting or grinding hard materials);
   • The high-temperature resistance adapts to the high temperature generated by the motor during long-term operation, reducing cracking or failure of the carbon brush due to overheating.
5. Replacement Tips:
   The carbon brush should be replaced in time when the electric tool shows the following conditions:
   • The carbon brush is worn down to less than 1/3 of its original length (about 7-8mm);
   • The sparks at the carbon brush increase significantly during motor operation, or are accompanied by a continuous "sizzling" sound;
   • The output torque of the tool decreases, or there is a shutdown or stuttering phenomenon under heavy load.
