Industrial Face Mask Chain Sprockets Pulley Block Transmission parts stainless steel plastic various material Chain
Product Description
Drive chains are precision-engineered power transmission components that transfer mechanical energy between shafts via sprockets. They convert rotary motion at a constant speed ratio, making them essential components in applications requiring positive engagement (no slip) and high torque density.
Key advantages over alternatives
Mechanical efficiency up to 96-98% (compared to 90-95% for belt drives)
Compact power transmission (higher power/space ratio than gear drives)
Tolerant misalignment (compared to gear drives)
No preload required (unlike belt drives)
Ability to operate in harsh conditions (dust, moisture, extreme temperatures)

Materials Science
Alloy steel: case hardening for wear resistance (commonly used SAE 4340)
Stainless steel: 304/316 for corrosion resistance
Special treatments:
Galvanizing: mild corrosion protection
Nickel coating: chemical resistance
DLC coating: for high wear applications
