About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX700-20
The AirTAC SAIJ200X700-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 680 to 700 mm. Delivering 15708 N of push force and 15080 N of pull force at 0.5 MPa, it is built for heavy-duty positioning. The unit utilizes a SUS420J2 stainless steel rod and PT tapered port threads to handle demanding industrial environments.
This model omits a piston magnet, so position sensing requires external switches rather than internal CMSE or DMSE sensors. The rear adjustment screw acts purely as a mechanical stop to fine-tune the retract end position during commissioning. It does not hold the load without live air pressure; for dead-end holding, a SAIL or BSAI series cylinder is required.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX700-20 Is Used
Heavy Press Positioning
Dial in the exact 680-700 mm end-stop for a large metalforming press, ensuring precise contact without repositioning the entire actuator assembly.
Pallet Changeover Stops
Adjust the retract stroke by up to 20 mm on the fly to accommodate different pallet depths arriving on a high-capacity conveyor line.
Large Assembly Jigs
Fine-tune the end-position of heavy automotive jigs at commissioning, leveraging 15708 N of thrust to move substantial structural components.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX700-20 the Right Cylinder?
Choose this 200 mm bore cylinder when an application demands substantial thrust, stepping up from the 160 mm bore that provides 10053 N of push force at 0.5 MPa. The 20 mm adjustable end-stop is ideal for fine-tuning tool positions during machine setup or product changeover without adding external physical stops. Because the 700 mm stroke is substantial, an external guide is strongly recommended to prevent excessive side-loading on the 40 mm rod and M36x2 rod thread.
For a true drop-in ISO 15552 replacement, match the 200 mm bore, 700 mm stroke, 20 mm adjustment, PT port, and the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). This profile cylinder uses an extruded aluminum barrel with sensor grooves on both sides, strictly avoiding tie-rod construction.
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 SAIJ200AX700-20 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 3204 kgf.
The rear adjuster screw allows you to shorten the nominal 700 mm stroke by up to 20 mm, providing a usable travel window of 680 to 700 mm. This mechanical stop fine-tunes the end position but does not lock the load without continuous air pressure.
