QGB Series: The Industrial Standard for Heavy-Duty Tie-Rod Cylinders
The QGB series is a robust and versatile standard pneumatic cylinder, widely recognized for its reliability in demanding industrial environments. Utilizing a traditional tie-rod construction, the QGB series offers exceptional structural stability and ease of maintenance, making it the "go-to" actuator for heavy-duty automation and machinery.
Advanced Engineering & Performance Features
Precision Adjustable Cushioning: Every QGB cylinder is equipped with high-efficiency adjustable air cushions at both ends. This ensures smooth deceleration, minimizes impact vibration, and significantly extends the life of the cylinder and the attached equipment.
High-Strength Tie-Rod Design: The external tie-rods are made of high-tensile steel, providing maximum rigidity to handle high-pressure surges and heavy mechanical loads without deformation.
Premium Material Selection:
Cylinder Barrel: High-precision anodized aluminum alloy (or honed steel for larger bores) for low friction and wear resistance.
Piston Rod: Hard-chromed carbon steel (Standard) or Stainless Steel (Optional) with a high-polish finish for superior seal life.
Seals: Durable NBR or Viton seals designed for high-frequency operation and long-term reliability.
Non-Lubricated Operation: Features self-lubricating bearings that eliminate the need for oil mist lubrication, ensuring a cleaner and lower-maintenance pneumatic system.
