RS2H80-40DM: Precision Locking, Safety Assured! Mechanical Locking Cylinder Empowers Safe Positioning Systems

In applications involving vertical lifting, tilting clamping, or requiring precise holding at intermediate positions, standard cylinders cannot prevent load movement due to gravity or external forces when air supply is cut off. The RS2H80-40DM is a cylinder with a mechanical locking device (Locking Cylinder), integrating actuation and rigid locking into one unit. It securely locks the piston rod in place during loss of air supply or power failure, providing reliable positioning and holding capability for safety-critical applications.Core Product Advantages

• Mechanical Locking, Safe & ReliableFeatures a built-in wedge force amplification or threaded locking mechanism. It automatically engages upon loss of air supply or system pressure drop, generating immense mechanical locking force to effectively prevent load descent or shifting, ensuring high safety.
• Locking at Any PositionCan lock and unlock at any intermediate point within the full piston rod stroke, offering flexible positioning to meet complex operational requirements.
• Large Bore, Powerful OutputWith an 80mm bore, it delivers strong thrust output (approximately 3500N at 0.7MPa air pressure), easily driving heavy loads.
• Heavy-Duty Cushioning ProtectionBuilt-in hydraulic cushions at both ends (DM likely indicates cushion type) effectively absorb impact energy at stroke ends, protecting the cylinder ends and equipment structure.
• Manual Emergency ReleaseIncludes a manual release function (e.g., manual screw or pull-cord), allowing manual disengagement of the lock during power or air failure for maintenance or emergency handling.

Typical Application Scenarios

• Vertical Lifting Mechanisms:​ Prevents platforms, robotic arms, etc., from descending under their own weight when air supply is cut.
• Tilting Clamping Devices:​ Ensures fixtures remain securely clamped in place during welding, handling, etc., even during pressure loss.
• Safety Support Mechanisms:​ Serves as the actuation and locking unit for safety guarding devices.
• Intermediate Position Holding:​ Applications requiring the cylinder to precisely position and hold at any point within its stroke.

Technical Parameters (Typical Values)

• Bore Size: 80mm
• Stroke: 40mm
• Operating Pressure: 0.1 ~ 1.0 MPa
• Locking Method: Spring-locked, Air-released (Normally Closed type)
• Locking Force: XXXX N (Refer to manual)

SummaryThe RS2H80-40DM Locking Cylinder is an “Integrated Actuation and Locking Solution” for safe positioning applications. It perfectly combines the driving function of a pneumatic cylinder with the safety assurance of mechanical locking, providing dual protection for applications with risks of potential falling or shifting.Choosing the RS2H80-40DM means choosing to equip your critical applications with the dual assurance of powerful actuation and secure locking!
