About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-75S
The AirTAC SAIJ200X220-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa, making it suitable for heavy-duty press and clamp operations. The integrated -S magnet enables position detection across the extruded aluminum barrel's dual sensor grooves using AirTAC CMSE reed or DMSE electronic solid-state switches.
By turning the external rear stopper screw, you can shorten the effective travel by up to 75 mm, creating a highly flexible 145 to 220 mm usable stroke window. This on-machine fine-tuning capability eliminates the need to swap out the entire cylinder or bolt on external physical stops when dialing in final end positions. Built with a SUS420J2 stainless steel rod (option A) and PT tapered port threads, it handles demanding environments while maintaining standard ISO 15552 mounting interface dimensions.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-75S Is Used
Heavy Press Setup
Dial in the exact 145 to 220 mm clamping depth on heavy stamping presses without machining custom external spacers.
Product Line Changeover
Rapidly adjust the rear stopper to accommodate new part lengths on a high-force assembly line during product transitions.
Variable End-Stop Clamping
Fine-tune the end-of-stroke position on large jigs where a fixed 220 mm stroke would apply too much overtravel force.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-75S the Right Cylinder?
Choose this 200 mm bore size when a 160 mm bore (providing 10053 N push at 0.5 MPa) lacks the necessary force for your heaviest fixtures. The SAIJ200X220-75-S is selected specifically when your assembly requires a variable end-stop, allowing you to trim the nominal 220 mm stroke back to a precise 145 mm limit during product changeovers. For any application requiring 300 mm or more of travel, external guide rails are recommended to manage side-load, though this 220 mm unit's 40 mm rod and M36x2 thread provide substantial rigidity.
Remember that the rear adjuster acts purely as a travel stop and the air cushions only manage deceleration; neither will hold a load safely without live air pressure. If your fixture requires true load-holding without continuous pneumatic pressure, you must integrate an external pilot-operated check valve, or switch to a SAIL pneumatic lock or BSAI clamp-lock cylinder. To match this ISO 15552 footprint exactly, specify a 200 mm bore, 220 mm stroke, 75 mm adjustment, PT port threads, and the -S magnet option.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-75S FAQ
At a 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it achieves up to 3204 kgf of thrust.
The rear adjuster screw allows you to mechanically shorten the nominal 220 mm stroke by up to 75 mm. This provides a usable travel window ranging from 145 mm to 220 mm, enabling precise end-position tuning at commissioning without replacing the cylinder.
