About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX100-20S
The AirTAC SAIJ200X100-20-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 80-100 mm, letting you trim the 100 mm nominal stroke by up to 20 mm during commissioning. Belonging to the 200 mm bore class, it generates 15708 N of push force and 15080 N of pull force at 0.5 MPa, making it ideal for heavy-duty positioning.
This variant includes a magnet for CMSE reed and DMSE electronic sensors, and uses a SUS420J2 stainless steel rod for enhanced corrosion resistance. It features PT tapered port threads (G3/4) and variable air cushions at both ends. The rear adjuster acts purely as a travel stop for end-position tuning, not as a lock, so it cannot hold a load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX100-20S Is Used
Heavy Press Changeover
Dial in the 80-100 mm travel window on the fly to accommodate varying material thicknesses during heavy pressing operations.
Actuator End-Tuning
Fine-tune the retract end-position during machine commissioning without machining new external stopper blocks.
Variable Stroke Forming
Adjust the stroke by up to 20 mm to handle different product sizes on a single heavy-duty forming line.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX100-20S the Right Cylinder?
Select this 200 mm bore cylinder when an application requires immense thrust along with precise end-stop tuning without external stops. If you need less force, stepping down to the 160 mm bore yields 10053 N of push force at 0.5 MPa. Choose the SAIJ adjustable-stroke design over a fixed-stroke SAI when you expect product changeovers or need to dial in the exact end position on the fly. To replace an ISO 15552 cylinder, match the 200 mm bore, 100 mm stroke, 20 mm adjustment, G3/4 PT ports, and the -S magnet option.
Because the nominal stroke is 100 mm, an external guide is not strictly required for side loads, but the robust 40 mm SUS420J2 rod helps manage mechanical stress. If your machine requires true load-holding without continuous air pressure, this cylinder will not suffice; instead, consider the SAIL series with an air-released lock or the BSAI clamp-lock variant.
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 SAIJ200AX100-20S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 3204 kgf.
The rear adjuster screw lets you shorten the 100 mm nominal stroke by up to 20 mm, creating an 80-100 mm usable travel window. The adjuster functions only as a mechanical stop and does not lock the load without live air.
