AutomationDirect’s NITRA pneumatic product line now includes D-Series double-acting heavy-duty air cylinders, designed for use where abusive conditions exist. These pneumatic air cylinders have a 250 psi operating pressure and are interchangeable with other popular brands. New models are now available with adjustable cushions to provide end-of-stroke deceleration at both ends. All D-Series cylinders are constructed with high-quality aluminum components and a magnetic piston fitted with a PTFE wear band; all cylinders can be used along with solid-state or reed switches for rod position sensing. The series includes bore sizes from 1.5 to four inches and stroke lengths from one to 24 inches to meet a broad range of applications. Models feature flange, rear clevis and rear pivot, side and rod clevis mounting options.
