Description

CQF Series: Compact Cylinder with Rod Flange Mounting

Space-Saving Industrial Pneumatic Solution with Integrated Front Flange

The CQF Series is a high-performance compact cylinder configuration designed for industrial automation where axial space is limited and rigid front-end mounting is required. By utilizing a specialized Rod Flange (Type F) bracket, this cylinder provides a stable mounting platform while maintaining the compact footprint characteristic of JIS-standard compact cylinders.

Key Features for Integration

Integrated Flange Mounting: The CQ-F code designates the inclusion of a high-rigidity front flange bracket, facilitating direct bolt-on installation to machine frames.
Auto Switch Capability: All units feature a built-in magnet as standard, with longitudinal grooves on the cylinder body for flush mounting of position sensors.
Space-Efficient Design: The C-clip connection between the body and covers ensures a shorter overall length compared to traditional tie-rod cylinders.
Material Quality: Constructed with an aluminum alloy cylinder tube (hard anodized) and carbon steel piston rods with hard chrome plating for enhanced abrasion resistance.
