AirTAC QCK Series: Heavy-Duty Rotary Clamp Cylinder
The AirTAC QCK Series is a specialized pneumatic rotary clamp engineered specifically for demanding industrial applications such as welding fixtures. This series features a superior QPQ surface treatment on the piston rod, which provides significantly better protection against welding slag damage compared to traditional chrome plating.
Designed for maximum internal protection, the QCK series includes a stainless steel dust scraping ring on the front cover to prevent dust and slag from compromising internal components. With its high magnetic field resistance and compatibility with standard ACQ series accessories, it is a versatile and durable choice for modern automation.
Key Features:
-
QPQ Surface Treatment: Highly resistant to welding slag, offering superior durability over standard chrome-plated rods.
-
Stainless Steel Dust Scraping Ring: Integrated into the front cover to block contaminants and protect internal cylinder parts.
-
Magnetic Field Compatibility: Optional strong magnets for bore sizes φ32~φ63 allow for reliable operation in high magnetic fields.
-
Standardized Mounting: The body mounting dimensions are identical to the ACQ series, allowing for seamless use of ACQ accessories.
-
Optimized for Welding: Specifically designed to withstand the harsh conditions of welding workshop environments.
