Roller chains are probably the most common and are used in a wide variety of low-speed to high-speed drives. Engineering steel chains are used in many low-speed high-load drives. Silent chains are mostly used in high-speed drives. Other types of standard chains and many types of special chains for unique applications may be found in manufacturers catalogs. Chains can span long center distances like belts and positively transmit speed and torque like gears. For a given ratio and power capacity chain drives are more .
