CJ2M16-75Z: Stainless Steel Mini Cylinder, Lightweight Compact Power Unit

Product Positioning
The CJ2M16-75Z is a double-acting, single-rod type mini cylinder from SMC’s CJ2-Z series, featuring a stainless steel cylinder tube and a basic mounting style. With its compact size, lightweight structure, and corrosion resistance of the stainless steel material, this series has become an ideal actuating element for achieving small to medium thrust linear motion in automation equipment. It is widely used in electronic assembly, packaging machinery, medical devices, and various industrial scenarios where space saving is critical.

Core Highlights: Stainless Steel Tube, Compact and Lightweight

• Stainless Steel Cylinder Tube, Strong Corrosion Resistance
  • The cylinder tube is made of stainless steel, offering excellent corrosion resistance suitable for dusty, humid, and general industrial environments.
  • The piston rod is also made of stainless steel, further enhancing overall durability and service life.
• Double-Acting Drive, Stable Thrust
  • Employs a double-acting design where compressed air drives both forward and return strokes, providing flexible and responsive motion.
  • Bore size Φ16mm, stroke 75mm, providing stable output thrust/pull force under standard air pressure.
• Compact Lightweight Design, Space Saving
  • As a mini cylinder series, the overall外形尺寸 is compact: Length 150mm × Width 18.3mm × Height 18.3mm, allowing easy installation in limited spaces.
  • Weight is only approx. 98.4g (body), with an additional 6.5g per mm of stroke. Low moving inertia enables fast response.
• Basic Mounting Style, Easy Integration
  • The “M” in the model represents the basic mounting style (Through-hole type). The body has through-holes for mounting, allowing fixation to equipment from multiple directions.
  • Port size is M5×0.8, and the rod end thread is M5×0.8 male, conforming to mini cylinder standards.
• Rubber Bumper, Smooth Stopping
  • Utilizes a rubber bumper cushioning method, effectively absorbing impact energy at the end of the piston stroke, achieving smooth stopping and protecting the cylinder and load equipment.
• Wide Range Adaptability, Stable Performance
  • Operating pressure range 0.06 to 0.7 MPa (max. 1.0 MPa), with a proof pressure of 1.5 MPa, adaptable to various conditions from low-pressure start-up to medium/high-pressure drive.
  • Ambient temperature range -10 to 70°C, suitable for most industrial environments.
