About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-75
The AirTAC SAIJ200X290-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, designed to fine-tune the retract end position without external stops. It provides a usable travel window of 215 to 290 mm, allowing precise end-position calibration during commissioning or product changeover. Built with a SUS420J2 stainless steel rod (option A) and PT tapered port threads, it delivers massive thrust up to 21991 N at 0.7 MPa.
This 200 mm bore actuator features a robust 40 mm rod and M36x2 thread, handling high side loads, while the extruded aluminum barrel incorporates sensor grooves on both sides. The rear adjuster acts purely as a mechanical stop to set deceleration and travel limits, meaning it cannot hold a load without live air pressure. For load-holding requirements, SAIL or BSAI variants are required.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-75 Is Used
Heavy Press Tuning
Dial in the exact 215-290 mm end-stop for heavy pressing operations, allowing precise calibration during product changeover without adding external mechanical stops.
Assembly Line Setup
Adjust the retract position on the fly during automated assembly line commissioning to accommodate varying product sizes and perfect the end-of-stroke positioning.
Large Material Alignment
Fine-tune the stroke on large material alignment stations, using the 75 mm adjustment window to adapt to different material widths while leveraging the 21991 N force.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX290-75 the Right Cylinder?
Choose this 200 mm bore model when your application demands maximum force, such as 21991 N push at 0.7 MPa, and requires variable end-stops. If the force is excessive, stepping down to a 160 mm bore reduces the push force to 14074 N at 0.7 MPa, offering a more compact and efficient solution. The adjustable stroke is specifically beneficial for machine setups requiring fine-tuning without swapping cylinders, contrasting with the fixed-stroke SAI type.
Because the stroke is 290 mm, the unsupported rod length requires an external guide to prevent side-load damage. To match this ISO 15552 cylinder for replacement, verify the 200 mm bore, 290 mm stroke, 75 mm adjustment, PT G3/4 port, and the correct mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that this specific configuration omits a magnet, so position sensing requires external methods rather than CMSE or DMSE switches.
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 SAIJ200AX290-75 FAQ
At 0.7 MPa operating pressure, the 200 mm bore provides a push force of 21991 N and a pull force of 15080 N. It can deliver a maximum push force of 28274 N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke back from the 290 mm nominal length, creating a usable travel window of 215 to 290 mm. It sets the end position but does not lock or hold the load without continuous air pressure.
