About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX90-30S
The AirTAC SAIJ200X90-30-S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty applications requiring exact end-position tuning. Featuring a 200mm bore, it delivers 15708N of push force at 0.5 MPa. The integrated rear adjuster provides a 30mm correction window, allowing you to dial in the effective travel anywhere between 60mm and 90mm without swapping out the entire unit.
This model features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the PT tapered ports ensure a robust pneumatic connection in demanding industrial environments.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX90-30S Is Used
Heavy Press Tuning
Fine-tune the 60-90mm travel window during heavy press commissioning to achieve exact material deformation without adding external mechanical stops.
Product Changeovers
Quickly adjust the rear stopper by up to 30mm on a packaging line to accommodate different product sizes while leveraging the 15708N push force.
Robotic Material Handling
Provides precise end-positioning for heavy payloads, utilizing the integrated magnet and DMSE electronic sensors for reliable stroke confirmation.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX90-30S the Right Cylinder?
Selecting this 200mm bore cylinder makes sense when your application demands massive thrust—up to 15708N at 0.5 MPa—alongside variable end-stop positioning. If you need less force, stepping down to a 160mm bore yields 10053N of push force at 0.5 MPa, but the SAIJ200X90-30-S is unmatched for high-load tasks. The adjustable stroke is perfect for machine setup and product changeovers, acting as a travel stop rather than a lock. It cannot hold a load without live air; for true load-holding, consider an external rod lock or the AirTAC SAIL/BSAI series. When replacing an ISO 15552 cylinder, match the 200mm bore, 90mm stroke, PT port, and mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAIJ200AX90-30S FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides a push force of 15708N and a pull force of 15080N. At the maximum pressure of 1.0 MPa, it delivers a maximum push force of 3204 kgf.
The rear adjusting screw acts as a mechanical stop that lets you shorten the effective stroke from its 90mm nominal length down to as little as 60mm. This allows precise end-position tuning at commissioning without changing the cylinder, though it does not lock the load without continuous air pressure.
