SHORT PITCH PRECISION ROLLER CHAINS (A SERIES)-Duplex roller chains & bushing chains
The structure of the double-row roller chain is relatively simple, and the installation and disassembly process does not need to move the connected two axes, which is convenient for maintenance and replacement， consists of two rows of parallel rollers mounted between the inner and the outer chain plates and connected by a pin shaft. This structure helps to reduce the friction and improve the transmission efficiency.
