About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX35-30
The AirTAC SAIJ200X35-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. With a nominal 35 mm stroke and a 30 mm adjustment range, you can dial back the effective travel to establish a precise 5-35 mm usable window. This massive 200 mm bore generates 15708 N of push force at 0.5 MPa, making it ideal for heavy-duty pressing. It uses a PT tapered port thread and a SUS420J2 stainless steel rod (code A) for superior corrosion resistance.
The rear adjustment mechanism acts purely as a mechanical stop to fine-tune the retract end position during commissioning without adding external stops. It is not a locking device; the cylinder cannot hold a load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series. This model includes variable air cushions at both ends and utilizes the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX35-30 Is Used
Heavy-Duty Pressing
Dial in the exact 5-35 mm travel window for precision pressing operations, ensuring consistent force application without over-travel.
Machine Changeover
Quickly adjust the end-stop position during product size transitions on a line, eliminating the need to physically swap out cylinders.
Heavy Assembly Jigs
Use the robust 15708 N push force to seat large components, relying on the rear stopper to finely tune the final seating depth.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX35-30 the Right Cylinder?
Choose this 200 mm bore when the 160 mm class (providing 10053 N at 0.5 MPa) is insufficient for your heavy press requirements. The adjustable stroke is perfect for product changeovers, allowing you to fine-tune the end position on the fly rather than swapping a fixed-stroke SAI cylinder. When replacing an ISO 15552 cylinder, match the 200 mm bore, 35 mm nominal stroke, 30 mm adjustment, PT G3/4 port, and SUS420J2 rod. Since the nominal stroke is 35 mm, it falls well under the 300 mm threshold, so side-load concerns from an unsupported rod are minimal. The 40 mm rod diameter and M36x2 thread provide high rigidity, though external guiding is always recommended for heavy loads.
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 SAIJ200AX35-30 FAQ
At a 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it delivers 3204 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 35 mm nominal stroke by up to 30 mm. This creates a usable travel window of 5 to 35 mm, allowing precise end-position tuning during setup without changing the cylinder.
