Delta Chain

Delta Chain

DELTA CHAIN is the highest power capacity timing belt OPTIBELT has ever created. It is 2X stronger than any rubber timing belt. This means more compact drive designs are possible and it can replace many chain drives.

DELTA CHAIN's performance properties can offer a superior choice in existing applications. Its carbon cord power capacity also allows DELTA CHAIN to replace roller chain as it needs no lubrication, runs quieter, is as durable, and requires less maintenance. In new drive designs, DELTA CHAIN can allow for more compact drive designs, save weight and increase efficiency.

The DELTA CHAIN belt is designed to be compatible with optibelt's DC pulleys (8MDC) and Gates Poly Chain® pulleys (8MGT2).
