RSDQB50-30BLZ: Powerful Locking, Secure Positioning! Heavy-Duty Locking Cylinder Empowers Safety-Critical Applications

In applications such as vertical lifting, inclined clamping, or any scenario requiring a cylinder to reliably lock in any position to prevent unintended movement due to external forces (like gravity or vibration), standard cylinders fall short. The RSDQB50-30BLZ is a heavy-duty cylinder with an integrated mechanical locking device. Combining robust actuation with rigid locking, it securely locks the piston rod in place during air/power loss, providing the ultimate solution for ensuring load safety and precise positioning.Core Product Advantages

• Powerful Mechanical Locking, Safe & Reliable​Features a built-in wedge-amplifying or threaded locking mechanism. Automatically engages upon air loss or system pressure failure, generating immense mechanical locking force. Effectively withstands heavy loads, preventing 100% load drift or slippage for intrinsic safety.
• Locking at Any Position​Can engage and disengage at any intermediate point along the piston rod’s entire stroke, offering unparalleled positioning flexibility to meet complex operational requirements.
• Large Bore, Robust Actuation​With a 50mm bore, it delivers powerful thrust (approximately 1375N at standard working pressure), effortlessly driving heavy loads.
• Heavy-Duty Cushioning & Protection​High-performance hydraulic cushions are integrated at both ends, effectively absorbing impact at stroke termination. This protects the cylinder and equipment structure, ensuring smooth, low-noise operation.
• Intelligent Position Feedback​The cylinder body is designed to support magnetic switch installation (indicated by “LZ”), enabling real-time, contactless detection of the piston’s extended/retracted or locked/unlocked status, providing precise feedback to the control system.

Typical Application Scenarios

• Vertical Lifting & Suspension:​ Preventing platforms, robotic arms, or suspended loads from dropping under their own weight during air loss.
• Safety Clamping & Molding:​ Ensuring clamps or molds in welding, stamping, or assembly applications remain absolutely locked on the workpiece even during pressure loss.
• Safety Guarding Devices:​ Serving as the actuation and locking unit for safety doors or protective covers, maintaining a closed position upon failure.
• Precise Mid-Stroke Holding:​ Applications requiring a load to be held at a specific point in the stroke for extended periods with high precision.
