The polygon drive has no dowel pins to replace or keyways to rebuild, self-centers on each application, and carries high torque within the shaft diameter. Hysteresis magnets provide smooth, consistent torque, and the headsets provide a tight application range for closures and containers. “Double encapsulated” hysteresis magnets are nickel plated and sealed in a stainless steel housing for protection from harsh operating environments. Standard 316 SS construction provides further protection from corrosive CIP wash down chemicals and rigorous operating conditions. Available exclusively through JD Machinery Sales and Service, Inc.
