About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX110-20S
The AirTAC SAIJ200X110-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 90-110 mm usable travel window by trimming up to 20 mm from the 110 mm nominal stroke, enabling precise end-position tuning during commissioning without external stops. As the largest bore in the SAIJ range, it generates 15708 N of push force and 15080 N of pull force at 0.5 MPa.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a piston magnet (-S) for electronic or reed sensing. It uses PT tapered ports and relies on a 50 mm air cushion at both ends to decelerate its high moving mass. The extruded aluminum barrel includes sensor grooves on both sides, and the rear adjuster functions strictly as a travel stop, not a load-holding lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX110-20S Is Used
Heavy Press Fine-Tuning
Dial in the exact 90-110 mm pressing distance on heavy assemblies without swapping cylinders or adding mechanical shims during setup.
Product Changeover Stops
Quickly adjust the retract end-position by up to 20 mm to accommodate varying product sizes on a high-force production line.
Large Fixture Positioning
Position massive 200 mm bore tooling with 15708 N of force, using the rear stopper to set precise retraction limits at commissioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX110-20S the Right Cylinder?
Selecting this 200 mm bore cylinder is ideal when your application requires the maximum thrust available in the SAIJ series, stepping up significantly from the 160 mm bore which provides 10053 N of push force at 0.5 MPa. The adjustable-stroke design is preferred over a fixed SAI model when you need variable end-stops for product changeovers, allowing you to fine-tune the 90-110 mm travel window on the fly.
When specifying a replacement, ensure you match the 200 mm bore, 110 mm nominal stroke, 20 mm adjustment range, PT port threads, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Because the rear adjuster and air cushions only manage travel deceleration, they will not hold a load without live air pressure; for true load-holding, consider the SAIL or BSAI series. Speeds range from 30-500 mm/s.
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 SAIJ200AX110-20S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It can deliver up to 3204 kgf at its maximum 1.0 MPa pressure rating.
The rear adjuster screw allows you to mechanically shorten the effective stroke from 110 mm down to 90 mm. This creates a 90-110 mm travel window for fine-tuning the end position at commissioning, but it acts as a stop, not a lock, meaning the cylinder requires live air to hold its position.
