About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX1000-20S
The AirTAC SAIJ200X1000-20-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window between 980 and 1000 mm. It delivers a robust 15708 N of push force at 0.5 MPa, making it suitable for moving heavy industrial loads. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position detection.
This specific configuration features a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and uses PT tapered port threads. The integrated magnet (-S) supports direct mounting of CMSE reed or DMSE electronic solid-state sensors. Variable air cushions at both ends manage deceleration, but note that the rear adjuster acts only as a travel stop, not a load-holding lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX1000-20S Is Used
Heavy Press Tuning
Dial in the exact 980-1000 mm travel during commissioning to set precise mechanical stops for high-force pressing operations without external shims.
Large Product Changeover
Quickly adjust the end-of-stroke position on packaging lines when transitioning between different large product sizes.
Automated Assembly Setup
Fine-tune the retract end position on heavy-duty assembly machinery to accommodate varying fixture heights and tooling lengths.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX1000-20S the Right Cylinder?
Selecting this 200 mm bore cylinder makes sense when your application requires up to 15708 N of push force at 0.5 MPa, or a massive 3204 kgf at 1.0 MPa. If your force requirements are lower, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa, which may reduce air consumption. Conversely, if you need less force, a 160 mm bore provides 10053 N of thrust at 0.5 MPa.
The adjustable stroke is ideal for machine setup and product changeovers, allowing you to dial in the exact end position without swapping cylinders or adding external stops. For replacing an ISO 15552 cylinder, match the 200 mm bore, 1000 mm stroke, PT G3/4 ports, and the -S magnet requirement. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is 1000 mm, the 40 mm rod diameter and M36x2 thread still require an external guide to prevent excessive side-loading on the piston. To hold a load securely without live air pressure, use a SAIL pneumatic lock, a BSAI clamp-lock, or an external rod lock.
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 SAIJ200AX1000-20S FAQ
At a 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the nominal 1000 mm down to 980 mm. This allows precise end-position tuning during setup, but it does not lock or hold the load without continuous air pressure.
