TWQ & TTQ Series: Precision Lever-Type Stopper Cylinders


The TWQ and TTQ series are specialized heavy-duty pneumatic actuators designed for the most demanding conveyor applications. Unlike standard vertical stoppers, these lever-type cylinders use a mechanical advantage and integrated cushioning to halt pallets smoothly, even when carrying high-inertia loads. They are the essential choice for high-speed automated production and sorting lines.

Key Technical Features & Engineering Highlights

  • High-Efficiency Shock Absorption: Equipped with an integrated, high-performance shock absorber (often adjustable) that ensures workpieces stop without a rebound, protecting delicate components and reducing noise.

  • Robust Lever Mechanism: The heavy-duty lever design is engineered to withstand massive frontal impact forces. The pivot points are reinforced to ensure long-term reliability under high-frequency operation.

  • Self-Locking Safety: The internal geometry provides a stable stop position, ensuring that even if air pressure fluctuates, the pallet remains securely held in place.

  • Space-Saving Profile: Designed with a compact aluminum alloy body, these cylinders are easy to install in low-profile conveyor frames where vertical space is limited.

  • Sensor-Ready Design: Features integrated slots for the flush mounting of magnetic auto-switches (sensors) for precise position feedback to the PLC.
