About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX950-75
The AirTAC SAIJ200X950-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the effective travel window from 875 to 950 mm without external stops. It delivers substantial thrust, providing 15708 N push force and 15080 N pull force at 0.5 MPa. This model features a robust 40 mm piston rod with an M36x2 thread and a PT tapered port to handle high flow requirements.
Built with a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance, this extruded aluminum barrel design omits tie-rods and includes sensor grooves on both sides. The rear adjuster acts purely as a travel stop for end-position tuning during machine setup; it does not hold the load without live air pressure, so applications requiring true load-holding must utilize a SAIL pneumatic lock or external rod lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX950-75 Is Used
Large Assembly Presses
Dial in the exact 875-950 mm end-stop during heavy assembly operations, ensuring precise positioning without needing to swap out large actuators for different product heights.
Automated Diverters
Adjust the retract position on the fly to accommodate varying pallet sizes on a conveyor line, using the rear stopper to instantly change the effective stroke window.
Heavy Machine Changeover
Quickly reconfigure long-stroke industrial machinery for new production runs by turning the rear adjuster, avoiding the mechanical downtime of installing external physical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX950-75 the Right Cylinder?
Choose this 200 mm bore when 0.5 MPa thrust of 15708 N is required, or step down to a 160 mm bore offering 10053 N if the load permits. The 75 mm adjustment range is ideal for production lines running mixed product sizes, letting operators dial in the exact end-stop during changeover instead of physically swapping cylinders. Because this SKU lacks the -S magnet option, position sensing via CMSE reed or DMSE electronic switches is not supported out of the box.
To replace an ISO 15552 cylinder, match the 200 mm bore, 950 mm stroke, 75 mm adjustment, PT port thread, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Given the 950 mm stroke, the 40 mm rod and M36x2 thread provide rigidity, but an external guide is strongly recommended to prevent excessive side-loading on the long unsupported travel. Speeds range from 30-500 mm/s, and the adjuster must never be relied upon as a braking lock.

- ✓ 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 SAIJ200AX950-75 FAQ
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At the maximum pressure of 1.0 MPa, the push force reaches 3204 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the 950 mm nominal stroke by up to 75 mm, providing an effective travel window of 875 to 950 mm. It is a travel stop for fine-tuning end positions, not a locking device, and cannot hold a load without continuous air pressure.
