Compact Cylinder Series CQS ø12, ø16, ø20, ø25 Ideal for machine designs with small space requirements Square body shape gives you flexibility for designing machine. The “D-M9” auto switch will not protrude from switch mounting groove. Cross-section of a cylinder tube is the same configuration regardless of w/ switch or w/o switch. Auto switch mounting allows for flexible designing requirements 2 way basic mounting: Through-hole or both ends tapped 3 faces on ø12, ø16, and all 4 faces including port side on ø20, ø25. Basic mounting is 2 way. You can choose either through-hole or both ends tapped mounting. Non-rotating accuracy Non-rotating rod Hexagonal cross sectional shape piston rod for high non-rotation accuracy. ø12, ø16 — ±1° ø20, ø25 — ±0.7° es n 4 sid able o Attach 0, ø25) (ø2 es n 3 sid able o Attach 2, ø16) (ø1 Auto switch Long Standard stroke stroke Double acting Single acting Double acting Anti-lateral Load Double acting Smooth cylinder (Low friction) Low-speed cylinder Refer to Best Pneumatics No. 3.

Specific Product Precautions Be sure to read before handling. Refer to front matters 54 and 55 for Safety Instructions and pages 3 to 11 for Actuator and Auto Switch Precautions. Retaining Ring Installation/Removal Caution 1. For installation and removal, use an appropriate pair of pliers (tool for installing a type C retaining ring). 2. Even if a proper plier (tool for installing type C retaining ring) is used, it is likely to inflict damage to a human body or peripheral equipment, as a retaining ring may be flown out of the tip of a plier (tool for installing a type C retaining ring).
