(1) Slack of 3.5 ~ 5.5 inches (during operation) is needed under the drive sprocket. (2) Engagement angle must be more than 150° between the drive sprocket and the chain. (3) The radius R (inches) of the guide rail must be larger than the radius of chain back-bend given in the table below. Radius of Chain Back-bend (in.) (in.)
Locations of the chain and the guide rail are very important for a smooth transition between conveyors. Two parallel chains must be positioned at the same height, or the output chain must be positioned slightly higher than the receiving chain. The guide rail must be shaped such that transition of goods can be accomplished smoothly.
