About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-40
The AirTAC SAIJ200X105-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 65 to 105 mm, enabling precise end-position tuning at commissioning without swapping the unit or adding external stops. Delivering immense thrust, it yields 21991 N of push force at 0.7 MPa and 15080 N of pull force.
This heavy-duty actuator uses a 40 mm SUS420J2 stainless steel rod (code A) with an M36x2 thread, paired with a PT G3/4 port for high airflow. It reaches a maximum speed of 500 mm/s and includes variable air cushions at both ends. The extruded aluminum barrel integrates dual sensor grooves, though this specific SKU omits the magnet for electronic sensing.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-40 Is Used
Heavy Press Tonnage Tuning
Dial in the exact 65 to 105 mm end-stop during heavy press commissioning to accommodate varying material thicknesses without re-mounting the actuator.
Automated Assembly Changeover
Rapidly adjust the retract position on automated assembly lines when switching between different product sizes, using the rear stopper to set new stroke limits.
Variable Position Damping
Leverage the 40 mm adjustment range alongside the built-in variable air cushions to perfectly tune the end-of-stroke deceleration for massive 200 mm bore payloads.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX105-40 the Right Cylinder?
Selecting this 200 mm bore model provides a maximum push force of 3204 kgf at 1.0 MPa, stepping up from the 160 mm bore which provides 2050 kgf. An adjustable stroke is chosen over a fixed SAI when a machine requires variable end-stops or product-size changeovers, allowing the rear screw to fine-tune the retract position. Because the stroke is 105 mm, external side-load guides are not strictly necessary, but the robust 40 mm rod inherently handles greater bending loads.
For an exact ISO 15552 replacement, match the 200 mm bore, 105 mm stroke, 40 mm adjustment, PT G3/4 port, and SUS420J2 rod material. Note that the rear adjuster acts as a travel stop and deceleration aid, not a lock; the SAIJ does not hold loads without live air. For pilot-operated load-holding, select an AirTAC SAIL or BSAI cylinder instead. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ200AX105-40 FAQ
At 0.5 MPa, it provides 15708 N push and 15080 N pull force. At 0.9 MPa, the push force increases to 28274 N, and it reaches a maximum push force of 3204 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that can shorten the 105 mm nominal stroke by up to 40 mm, creating a usable travel window of 65 to 105 mm. It only sets the end position and does not lock the load without live air pressure.
