About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX270-100
The AirTAC SAIJ200X270-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel by up to 100 mm. This creates a usable window of 170 to 270 mm, letting you dial in the exact end position at commissioning without swapping the barrel or adding external stops. Built to deliver massive thrust, it pushes with 15708 N and pulls with 15080 N at 0.5 MPa, reaching a maximum of 3204 kgf at 1.0 MPa.
This unit uses a SUS304 stainless steel rod for superior corrosion resistance and carries PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the rear adjuster acts purely as a travel stop—it does not hold the load without live air pressure. For load-holding without continuous air, an external rod lock or the SAIL/BSAI series is required.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX270-100 Is Used
Heavy Press Setup
Fine-tune the 170-270 mm travel window during machine commissioning to set precise pressing depths on heavy assemblies without changing hardware.
Product Changeover
Dial in new end-stops on automated lines when switching product sizes, using the 100 mm rear adjustment range to adapt the stroke instantly.
Variable End-Stop Tooling
Use the rear stopper to modify the retraction point on large material handling equipment, accommodating different material thicknesses on the fly.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX270-100 the Right Cylinder?
Choose this 200 mm bore when the 160 mm class (10053 N push at 0.5 MPa) is insufficient for your heaviest pushing and pulling tasks. An adjustable stroke is selected over a fixed SAI when a machine requires variable end-stops for product changeovers or fine-tuning during setup.
With a 270 mm stroke, the 40 mm diameter rod and M36x2 thread provide rigidity, but an external guide is recommended to prevent side-loading damage. To replace an ISO 15552 cylinder, match the 200 mm bore, 270 mm stroke, 100 mm adjustment, PT G3/4 ports, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts. No magnet is installed, so CMSE or DMSE sensors cannot be used without modification.

- ✓ 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 SAIJ200BX270-100 FAQ
At 0.5 MPa, the push force is 15708 N and the pull force is 15080 N. At the maximum operating pressure of 1.0 MPa, it achieves a push force of 3204 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the 270 mm nominal stroke by up to 100 mm, providing an effective travel range of 170 to 270 mm for precise end-position tuning.
