• Double Plus Chain
• Standard Top Roller Chain
• Side Roller Chain
• Center Roller Chain

Double plus Chain (also called Triple Speed chains) are used typically on accumulating assembly line conveyors. This chain operates in a specially designed aluminum track. Small rollers turn the large rollers by friction as the chain travels in the track causing materials on the top of the chain to travel at approximately 2.5 times the linear speed of the chain. Double Plus Chain are available with 'snap covers' to keep particles out, in resin rollers and with protective coatings (nickel, chromium plating).
