NAMUR Mounting - Allows standardization of mounting hardware for a wide range of shaft-driven accessories.
Replaceable Bearings - Protects sliding and rotating components, and are suitable for dry or lubricated working conditions.
PTFE Guide Ring - Prevents contact between the metal surfaces of the piston and pneumatic cylinder, prevents internal damage to the cylinder while providing self-lubrication and low friction.
Integral Housing Vent - Releases overpressure while preventing ingress of foreign objects or water.
Travel Adjustment - Bi-directional travel stop allows an adjustable stroke range of 80 degrees to 100 degrees.
Roller - Connects the Scotch yoke and yoke pin, reducing friction and wear between both components.
Safe Spring Lock
PTFE Guide Bar - Prevents yoke pin axial movement, transfers axial loads directly to the drive module case.
Spring Module with Hydraulic Override - Located inside the hydraulic override cylinder module on spring-return models so that the actuator length is not increased.
