About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX100-75S
The AirTAC SAIJ200X100-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers massive thrust, pushing 28274N at 0.9 MPa, making it suited to heavy-duty tasks. The built-in -75 mm adjustment screw allows you to trim the nominal 100 mm stroke back, providing a usable travel window of 25 to 100 mm for exact end-position tuning during commissioning.
This variant includes a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and is equipped with a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the G3/4 PT port handles the high airflow required to move the 40 mm rod at speeds of 30-500 mm/s.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX100-75S Is Used
Heavy Press Tuning
Dial in the exact 25-100 mm travel window during machine setup to apply maximum pressing force without over-traveling the tooling.
Product Changeover
Quickly adjust the retract end-stop on a packaging line to handle different product sizes without physically changing the ISO 15552 cylinder.
Large Assembly Jigs
Use the massive 28274N push force at 0.9 MPa to seat large components, relying on the rear screw to set the precise final position.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX100-75S the Right Cylinder?
Choose this 200 mm bore if your application requires extreme force, delivering 15708N of push thrust at a conservative 0.5 MPa. If you do not need this much power, stepping down to a 160 mm bore yields 10053N at 0.5 MPa, reducing air consumption. The adjustable stroke is ideal for product changeovers, letting you fine-tune the end-stop without adding external shims or swapping the cylinder. Because the nominal 100 mm stroke is below the 300 mm threshold, external guide requirements are less critical, though the 40 mm rod and M36x2 thread handle substantial side loads.
When selecting a drop-in replacement, match the 200 mm bore, 100 mm nominal stroke, 75 mm adjustment range, G3/4 PT port, and the -S magnet. Remember that the rear adjuster acts only as a travel stop and cannot hold a load without live air pressure. For true fail-safe load holding, consider the SAIL pneumatic lock or BSAI clamp-lock cylinder instead. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and 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 SAIJ200AX100-75S FAQ
At 0.9 MPa, this 200 mm bore cylinder provides a push force of 28274N and a pull force of 15080N. It can deliver a maximum push force of 3204 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the effective travel from the nominal 100 mm stroke by up to 75 mm. This creates a usable adjustable stroke window of 25 to 100 mm, allowing precise end-position tuning at commissioning without external stops.
