About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX180-30
The AirTAC SAIJ200X180-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the nominal 180 mm travel back by up to 30 mm. This creates a precise 150-180 mm usable travel window, letting you dial in the exact retract end-position during commissioning without adding external stops. It delivers massive thrust, pushing 21991 N at 0.7 MPa and 28274 N at 0.9 MPa, making it suited for heavy-duty positioning.
This variant is configured with a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for mounting AirTAC CMSE reed or DMSE electronic solid-state switches. The SAIJ mounting set is restricted to Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets to streamline heavy-duty profile mounting.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX180-30 Is Used
Heavy Press Positioning
Dial in the 150-180 mm retract window to set precise bottoming positions for large industrial presses during product changeovers.
Variable End-Stop Setup
Use the 30 mm rear adjuster to fine-tune the end-of-stroke position at commissioning without swapping out the entire cylinder or adding external mechanical stops.
Large Fixture Actuation
Leverage the 28274 N push force at 0.9 MPa to move and position massive production line fixtures reliably within a tight travel tolerance.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX180-30 the Right Cylinder?
Choose this 200 mm bore size when your application requires maximum force, stepping up significantly from the 160 mm bore which pushes 14074 N at 0.7 MPa. The adjustable stroke is ideal for machine setups requiring variable end-stops or product-size changeovers, providing fine-tuning flexibility that a fixed-stroke SAI cylinder cannot match. Because the rear adjuster acts only as a travel stop and the air cushions manage deceleration, neither will hold a load without live air pressure; for true load-holding, select the SAIL air-released lock or BSAI clamp-lock cylinder. To replace this cylinder with an ISO 15552 equivalent, match the 200 mm bore, 180 mm stroke, 30 mm adjustment, G3/4 PT ports, and the specified mounting bracket.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAIJ200AX180-30 FAQ
At an operating pressure of 0.9 MPa, this 200 mm bore cylinder delivers a push force of 28274 N and a pull force of 15080 N. It can generate a maximum force of 3204 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the nominal 180 mm stroke by up to 30 mm, providing an adjustable travel window between 150 mm and 180 mm to fine-tune the end position without replacing the cylinder.
