Detailed Product Introduction: New Original SMC CQ2KB40-100DMZ Compact Cylinder<\/h1>\n<\/div>\n
\n

1. Product Overview<\/h2>\n<\/div>\n
\n
The CQ2KB40-100DMZ is an authentic original compact pneumatic cylinder belonging to SMC CQ2 ultra-thin compact cylinder series. This product is specially developed for limited installation space inside automated equipment, abandoning the traditional long cylindrical cylinder structure and adopting a flat square integrated design to greatly reduce axial occupied space. Model coding explanation: 40 means cylinder bore diameter 40 mm; 100 stands for piston stroke 100 mm; suffix DMZ represents double acting type, built-in air cushions on both ends, with magnetic piston for position sensor installation and no rod rotation prevention structure. It outputs linear push and pull force driven by compressed air, mainly used for clamping, lifting, material ejection, positioning and pressing actions on automation production lines, packaging machinery, electronic assembly equipment, precision testing jigs and logistics conveying devices. Compared with standard stroke cylinders, this ultra-compact layout perfectly adapts to narrow mechanical installation cavities, and standardized interfaces bring good versatility for equipment assembly and replacement.<\/div>\n<\/div>\n
\n

2. Main Functions<\/h2>\n<\/div>\n
\n
    \n
  1. Double-acting bidirectional linear driving: Compressed air alternately enters front and rear air chambers to push the piston rod to extend and retract reciprocally, providing stable thrust and tension for mechanical execution components.<\/li>\n
  2. Built-in permanent magnet piston: Permanent magnet is embedded inside the piston body, which can cooperate with SMC magnetic auto switches installed on the cylinder side wall to feedback stroke limit signals for automatic control loop.<\/li>\n
  3. Dual-end adjustable air buffer: Air buffer structures are arranged at both stroke terminals to buffer piston impact, lower operating noise and avoid structural damage caused by rigid collision.<\/li>\n
  4. Anti-lateral load optimized structure: Square cylinder body enhances overall rigidity, can bear partial lateral force during operation without deformation or clamping stagnation.<\/li>\n
  5. Multi-directional installation adaptability: Flat cylinder outline supports front mounting, rear mounting and side mounting modes to match diverse equipment layout demands.<\/li>\n<\/ol>\n<\/div>\n

      5. Core Technical Features<\/h2>\n<\/div>\n
      \n
        \n
      1. Ultra-flat compact design: Short axial overall size saves over 40% installation space compared with standard round cylinders of the same bore and stroke, ideal for compact automated machinery.<\/li>\n
      2. High-rigidity aluminum alloy cylinder block: Integrally die-cast molding improves structural stability, resistant to vibration and slight impact in continuous production environment.<\/li>\n
      3. Low-friction sealing system: Precision composite sealing rings ensure smooth piston movement without creeping under low air pressure, effectively reducing air leakage and extending service life.<\/li>\n
      4. Convenient sensor installation: Sliding grooves on two side surfaces of the cylinder allow free sliding and locking of magnetic switches to adjust detection positions arbitrarily.<\/li>\n
      5. Adjustable air cushion performance: The buffer speed can be fine-tuned via small adjusting screws at both ends to adapt to different load weights and movement speeds.<\/li>\n
      6. Excellent wear-resistant piston rod: Thick hard chrome plating layer enhances scratch resistance and corrosion resistance, suitable for long-time continuous cyclic operation.<\/li>\n
      7. Lightweight structure: Aluminum main body greatly reduces self-weight, lowering extra load borne by equipment brackets.<\/li>\n<\/ol>\n<\/div>\n
