The RQ Series Compact Cylinder (With Air Cushion) is designed for applications requiring compact installation and enhanced cushioning performance. Its innovative air cushion mechanism improves shock absorption while adding only a few millimeters to the overall cylinder length.
Compared with conventional compact cylinders such as CQ2 and CQS, the RQ Series offers approximately twice the cushioning capacity and improved repeat positioning accuracy, making it suitable for high-speed and precision automation equipment.
The RQ Series Compact Cylinder is an advanced compact pneumatic actuator featuring an integrated air cushioning system. Designed for modern automation equipment, it combines space-saving dimensions with enhanced motion control, providing smoother operation and reduced mechanical impact.
A newly developed cushion mechanism eliminates the need for a traditional cushion sleeve, allowing the cylinder to maintain a compact profile while significantly improving cushioning performance.
