About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-100
The AirTAC SAIJ200X230-100 is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical stopper, allowing you to dial back the nominal 230 mm stroke by up to 100 mm. This yields a highly flexible 130-230 mm usable travel window, perfect for dialing in exact end positions during commissioning without swapping hardware. It delivers immense thrust, pushing 21991 N and pulling 21272 N at 0.7 MPa.
This variant features a SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes PT tapered port threads. The robust 40 mm rod and M36x2 thread handle significant side loads, though an external guide remains essential for this mass-class actuator. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches, provided a magnet is specified.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-100 Is Used
Variable End-Stop Positioning
Dial in the exact retract distance between 130 and 230 mm during machine setup to accommodate changing part widths without physically replacing the actuator.
Commissioning Fine-Tuning
Use the 100 mm rear adjustment window to perfect end-of-stroke positioning and compensate for mechanical tolerance stack-ups during line installation.
Heavy-Duty Forming Press
Leverage the 21991 N push force at 0.7 MPa for high-tonnage pressing or holding operations, using the adjuster to set the precise lower dead center.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-100 the Right Cylinder?
Choose this 200 mm bore when your application requires maximum force, as stepping down to a 160 mm bore drops your 0.7 MPa push force to 14074 N. The 100 mm adjustment range is ideal for machinery that processes varying product sizes, letting operators fine-tune the retract end-stop on the fly rather than adding external stops or resorting to a fixed-stroke SAI cylinder. Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because the stroke is 230 mm, ensure proper external guiding to prevent excessive side-loading on the rod. Remember that the rear adjuster acts only as a travel stop; it will not hold a load without live air pressure. For true fail-safe load holding, consider an SAIL or BSAI cylinder instead.
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 SAIJ200AX230-100 FAQ
At a 0.7 MPa operating pressure, this 200 mm bore cylinder generates a push force of 21991 N and a pull force of 21272 N. It can deliver up to 28274 N push at its maximum 1.0 MPa pressure.
A rear stopper screw lets you shorten the 230 mm nominal stroke by up to 100 mm, providing an effective 130 to 230 mm travel window. This stopper sets the end position but does not lock the load without continuous air pressure.
