Double Plus Chains Double Plus Chain (also called Triple Speed chains) are used typically on accumulating assembly line conveyors. This chain's two rollers rotate identically according to the frictional force between the large and small rollers. Items are conveyed about 2.5 times faster than the speed of the chain (the chain speed according to the ratio of the roller's outer diameter) In addition, when braking forces are applied, slip occurs between the large and small rollers, making the chain to be conveyed freely. Double Plus Chain are available with 'snap covers' to keep particles out, in resin rollers and with protective coatings (nickel, chromium plating).
