About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX700-40
The AirTAC SAIJ200X700-40 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, delivering a substantial 18095N of push force at 0.9 MPa. It features an extruded aluminum barrel with dual sensor grooves, utilizing a robust 40mm diameter carbon steel rod paired with an M36x2 thread. A PT tapered port thread ensures secure high-flow pneumatic connections.
Equipped with a rear mechanical stopper, this model allows you to fine-tune the end position during commissioning, creating a usable travel window of 660 to 700mm. The rod is constructed from SUS420J2 stainless steel (code A) for enhanced durability against harsh environments. As a profile cylinder, it is dimensionally interchangeable per ISO 15552, utilizing a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX700-40 Is Used
Heavy Machinery Positioning
Dials in the exact retract position of large fabricated components during assembly, using the 660-700mm travel window to compensate for frame tolerances.
Product Size Changeovers
Adapts automated heavy-load lines to different product lengths on the fly by turning the rear stopper, avoiding the need to physically replace the cylinder.
Large Press Tuning
Provides minute end-position adjustments for high-tonnage pressing operations, ensuring precise bottoming out without adding external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX700-40 the Right Cylinder?
Selecting this 200mm bore cylinder is appropriate when your application requires up to 18095N of push force at 0.9 MPa. If your load requirements are lower, stepping down to a 160mm bore provides 14074N of push force at 0.7 MPa, which may reduce air consumption. The adjustable stroke is chosen over a fixed SAI cylinder when you need variable end-stops for product size changeovers without physically swapping the actuator. Because this unit lacks a magnet, position sensing requires external methods rather than CMSE or DMSE switches.
For any stroke length of 700mm, the extended travel necessitates careful alignment to prevent excessive side-loading on the rod; always utilize an external guide to support the load. Remember that the rear adjuster functions strictly as a travel stop to set deceleration, not as a locking device. The cylinder cannot hold a load without live air pressure, so integrate an external rod lock, a pilot-operated check valve, or select a BSAI clamp-lock cylinder if static holding is required.
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 SAIJ200AX700-40 FAQ
At an operating pressure of 0.9 MPa, this 200mm bore cylinder generates a push force of 18095N and a pull force of 15080N. It operates efficiently at speeds between 30 and 500 mm/s.
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke back by up to 40mm, providing a usable travel window of 660 to 700mm. It only sets the travel end and does not lock or hold the load without continuous air pressure.
