Description

ACQJ Series: Double-Rod Adjustable Stroke Compact Cylinder

High-Precision Linear Motion with Customizable Stroke Control

The ACQJ Series is a specialized compact pneumatic cylinder designed for industrial automation requiring both dual-rod stability and adjustable end-of-stroke positioning. Built to JIS standards, this series utilizes a space-saving design where the cylinder body and covers are secured with C-clips, making it an ideal solution for tight installation environments without compromising on structural integrity.

Key Performance Features

Adjustable Stroke Mechanism: The ACQJ features a rear-mounted adjustment nut allowing for precise stroke tuning. Standard adjustment ranges include 10, 20, 30, 40, 50, 75, and 100mm.
Dual-Rod Stability: The double-shaft design provides enhanced non-rotating accuracy and resistance to torque compared to single-rod cylinders.
Advanced Surface Treatment: The internal diameter of the aluminum body is treated with hard-anodizing to ensure superior abrasion resistance and durability.
Flexible Integration: Features integrated slots for magnetic sensors and supports multiple mounting configurations including Front Flange (FA), Back Flange (FB), Foot Brackets (LB), and Pivot Brackets (CB).

Installation & Maintenance Notes

System Cleanliness: Ensure all piping is thoroughly cleaned of debris before connecting to the cylinder.
Filtration: A 40μm filter element is required to maintain the integrity of internal seals.
Side Loading: Avoid excessive lateral loads on the piston rod to prevent premature wear of the guide bushings.
Environment: For high-temperature or corrosive environments, specialized customized seals must be requested
