About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-30
The AirTAC SAIJ200X170-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 140-170mm usable travel window by allowing you to dial back the 170mm nominal stroke by up to 30mm. Built for heavy-duty tasks, it generates 15708N of push force and 15080N of pull force at 0.5MPa.
This large-bore unit features a SUS420J2 stainless steel rod for improved corrosion resistance and uses PT tapered ports. The rear adjuster acts purely as a mechanical stop for end-position tuning during commissioning; it does not lock or hold the load without live air pressure. For load-holding requirements, external rod locks or related SAIL and BSAI series cylinders are required.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-30 Is Used
Heavy Press Tuning
Dial in the exact 140-170mm end-position for heavy pressing operations without adding external mechanical stops.
Product Size Changeover
Quickly adapt a production line for different product heights by adjusting the rear stopper screw during setup.
Variable End-Stop Clamping
Provide adjustable clamping depths for large components using the 30mm travel window fine-tuning capability.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX170-30 the Right Cylinder?
Select this 200mm bore cylinder when your application requires massive thrust, stepping up significantly from the 160mm bore which provides 10053N of push force at 0.5MPa. The adjustable 140-170mm travel window is ideal for machinery requiring variable end-stops or rapid product-size changeovers, preventing the need to physically swap out a fixed-stroke SAI cylinder.
When integrating this ISO 15552 dimensionally interchangeable profile cylinder, verify your setup matches the required PT port thread, 170mm stroke, 30mm adjustment range, and the SAIJ mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke exceeds 300mm in larger configurations external guides are critical, but even at 170mm the heavy 40mm rod and M36x2 thread require careful alignment to manage side loads.
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 SAIJ200AX170-30 FAQ
