What is the difference between linear pitch and linear speed?
For each revolution of the shaft, a rolling ring drive travels a set distance. This distance is the linear pitch of the drive. The Amacoil RG drive offers infinitely variable pitch. The RS drive is a fixed pitch model offering five different pitch settings. Linear speed is the distance traveled per unit of time. For example, five feet per second. Amacoil/Uhing rolling ring assemblies offer linear speeds of up to 13 ft./sec. over a maximum distance of 16 feet.
