Effective operation of roller chain and gear couplings requires proper alignment and lubrication.
Roller chain coupling are compact and flexible couplings. They are used for low to moderate speed/torque applications. For effective operation they need to be maintained by applying lubrication and aligning.
Gear couplings are used for high speed and torque applications. For effective performance they need to be lubricated frequently and proper alignment is needed.
Hence effective operation of roller chain and gear couplings requires proper lubrication and alignment.
