About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX75-30
The AirTAC SAIJ200X75-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 45-75 mm usable travel window from its 75 mm nominal stroke. Delivering 15708 N of push force at 0.5 MPa, this massive 200 mm bore unit handles heavy press and lift duties. It uses a SUS420J2 stainless steel rod for superior corrosion resistance and carries a G3/4 PT port. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
The rear adjuster screw acts as a hard travel stop, allowing you to fine-tune the retract end position during commissioning without adding external stops. It is not a locking device; the cylinder relies on live air to hold load, so an external rod lock or SAIL cylinder is needed for fail-safe holding. Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX75-30 Is Used
Heavy Press Tuning
Dial in the exact 45-75 mm travel window during heavy press setup to accommodate different material thicknesses without changing the cylinder.
Product Changeover
Adjust the retract end-stop on the fly during production line changeovers to handle varying product sizes efficiently.
Large Assembly Clamping
Fine-tune the clamping end-position on large assemblies, using the 15708 N thrust at 0.5 MPa to secure heavy components.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX75-30 the Right Cylinder?
Select this 200 mm bore when your application requires extreme thrust up to 15708 N at 0.5 MPa, but you need the flexibility to dial back the stroke by up to 30 mm. If you need less force, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa. Choose the adjustable SAIJ over a fixed SAI when your machine setup requires variable end-stops for product changeovers.
This model features a PT tapered port and a SUS420J2 stainless steel rod. Because it lacks an -S magnet, it cannot use CMSE or DMSE sensors. The 40 mm rod and M36x2 thread handle high side loads, but even with a robust rod, any stroke over 300 mm requires an external guide to prevent binding. For load-holding without air pressure, use a SAIL or BSAI cylinder instead of relying on the adjuster.
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 SAIJ200AX75-30 FAQ
The rear adjuster screw lets you shorten the 75 mm nominal stroke by up to 30 mm, creating a 45-75 mm usable travel window. This stopper sets the end position but does not lock the load without live air pressure.
At 0.5 MPa it provides 15708 N of push force and 15080 N of pull force. At 0.9 MPa, the push force reaches 28274 N.
