About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX240-100
The AirTAC SAIJ200X240-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits an effective travel window of 140-240 mm from its 240 mm nominal stroke. Equipped with a robust 40 mm SUS420J2 stainless steel rod and PT tapered G3/4 ports, it belongs to the highest force class in the SAIJ family, generating 15708 N of push thrust and 15080 N of pull thrust at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position feedback integration.
By turning the external rear stopper screw, technicians can trim the retract end-position by up to 100 mm during commissioning without swapping out the cylinder or fabricating external mechanical stops. This adjuster acts purely as a travel stop to set the end-of-stroke deceleration point alongside the variable air cushions; it is not a lock. For applications requiring true fail-safe load holding without live air pressure, a dedicated SAIL pneumatic lock or BSAI clamp-lock cylinder is required.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX240-100 Is Used
Heavy Press Tuning
Dial in the exact 140-240 mm travel window on heavy metal presses during setup, allowing precise end-position tweaking without machining custom external stopper blocks.
Product Changeover
Adapt large-scale automated machinery to varying product sizes instantly by adjusting the rear stopper screw up to 100 mm, drastically reducing line downtime.
Heavy Load Positioning
Move substantial masses along a conveyor or assembly line, relying on the 15708 N push force at 0.5 MPa while fine-tuning the final retract position.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX240-100 the Right Cylinder?
Choose this 200 mm bore unit when your application demands maximum thrust that smaller neighbors cannot provide, such as upgrading from a 160 mm bore that yields 10053 N of push force at 0.5 MPa. The adjustable stroke is ideal for heavy machinery requiring precise end-position tuning during product changeovers, whereas a fixed-stroke SAI cylinder locks you into a single unchangeable travel length.
When matching this ISO 15552 dimensionally interchangeable cylinder for a retrofit, verify the 240 mm stroke, 100 mm adjustment range, PT G3/4 port thread, and the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is 240 mm, ensure adequate external guide support to prevent side-loading forces from damaging the large 40 mm rod and its M36x2 thread.

- ✓ 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 SAIJ200AX240-100 FAQ
The rear adjuster screw allows you to shorten the effective travel from the 240 mm nominal stroke down to a minimum of 140 mm, creating a 100 mm tuning window. This stopper mechanically limits the retract end-position to help decelerate the load, but it does not lock or hold the load without continuous live air pressure.
At a 0.5 MPa operating pressure, the SAIJ200X240-100 generates 15708 N of push thrust and 15080 N of pull thrust. It operates at a maximum speed of 30-500 mm/s and features a 40 mm SUS420J2 stainless steel rod for high structural rigidity.
