MKB25-30LZ: Compact & Powerful, Precision Drive! Clamping Cylinders Enable Secure Positioning

In safety-critical applications where the piston rod of a cylinder must be mechanically locked at any point within its stroke to prevent unintended movement caused by external forces (e.g., load gravity, vibration), standard cylinders fall short. The MKB25-30LZ is a cylinder with an integrated clamping device, combining actuation and mechanical locking into a single unit. With its reliable clamping force and high safety, it is the ideal choice for safety-dependent applications like vertical lifting and angular clamping.Core Product Advantages

• Secure Mechanical LockingFeatures a built-in wedge- or screw-type clamping mechanism. In the event of air supply loss or system pressure drop, it automatically or can be triggered to lock the piston rod, generating substantial mechanical clamping force to effectively prevent load descent or shifting, ensuring safety and reliability.
• Locking at Any PositionCan be clamped and released at any intermediate point along the piston rod’s full stroke, offering flexible positioning to meet the demands of complex working conditions.
• Stable Double-Acting DriveThe cylinder utilizes a double-acting design, achieving piston rod extension and retraction via alternating air supply. This provides balanced output force and smooth movement.
• Compact, Integrated DesignThe cylinder and clamping mechanism are highly integrated into a compact structure, saving installation space and simplifying equipment design.
• Manual Emergency ReleaseIncludes a manual release function (e.g., manual screw or pull-cord), allowing the clamp to be disengaged manually during power or air loss for easier maintenance or emergency handling.

Typical Application Scenarios

• Vertical Lifting Mechanisms:​ Prevents platforms, robotic arms, etc., from descending under their own weight if air pressure is lost.
• Angular Clamping Devices:​ Ensures clamps in welding or handling applications remain securely locked on workpieces even during pressure loss.
• Safety Support Mechanisms:​ Serves as the actuation and locking unit for safety guarding devices.
• Mid-Stroke Positioning:​ Achieves precise positioning and holding at intermediate points of the cylinder stroke.
