CKZT25-90S-X2797: Powerful Clamp Cylinder – Reliable Gripping Expert for Compact Welding Stations

Product Positioning
The CKZT25-90S-X2797 is a powerful clamp cylinder (basic type) from SMC’s CKZT series, featuring the X2797 custom specification designed to withstand welding spatter and harsh environments. It is specifically engineered for automotive welding lines, automated assembly, and heavy-duty clamping applications. Its core advantages lie in its compact, lightweight design, high clamping force, and excellent spatter resistance, making it an ideal actuation element for achieving secure clamping in confined spaces.

Core Highlights: Compact & Lightweight, Welding-Specific, 90° Opening Angle

• Compact & Lightweight Design for Space Savings
  • For the Φ25mm bore size, the width is only 34mm, and the height is 192.4mm (with arm open at 90°), achieving extreme miniaturization while ensuring clamping force.
  • Weighing only 580g, it significantly reduces moving inertia and improves response speed.
• X2797 Custom Specification – Welding Spatter Resistant
  • The suffix “-X2797” denotes SMC’s custom specification designed for weld spatter and water resistance.
  • This specification effectively prevents welding sparks and spatter from entering the cylinder interior, significantly extending its service life in harsh environments.
• Standard 90° Opening Angle for Flexible Adaptation
  • “90S” in the model indicates an arm opening angle of 90°, one of the most commonly used angles in industrial clamping applications.
  • The CKZT series offers 9 standard opening angles from 30° to 135°; this model is the basic type with a 90° opening.
• Strong Clamping Force for Secure Holding
  • With a Φ25mm bore, it provides stable clamping output force at a standard 0.5MPa air source.
  • For reference, the same series with a Φ32mm bore delivers a clamping force of up to 1100N (at 50mm arm length, 0.5MPa); the Φ25 model also offers excellent clamping capabilities with appropriate arm length.
• Basic Type without Arm for Flexible Selection
  • This model is the base type, supplied without a clamp arm.
  • Users can select and install suitable clamp arms (e.g., straight arm, L-shaped arm) based on actual workpiece shape and clamping requirements, greatly enhancing design flexibility.
• High Protection & Durable Design
  • Max. operating pressure: 0.8 MPa; proof pressure: 1.2 MPa.
  • Ambient temperature range: -10 to 60°C, suitable for most industrial environments.
  • Optional rubber or metal end cover; this specification includes a rubber end cover (X2797), effectively absorbing impact during arm return.
