About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX700-75
The AirTAC SAIJ200X700-75 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 625 to 700 mm, allowing you to dial back the end position by up to 75 mm during commissioning without adding external stops. In the 200 mm bore class, it generates a substantial 15708 N of push force and 15080 N of pull force at 0.5 MPa, making it suitable for moving heavy loads.
This variant features a SUS420J2 stainless steel rod (material code A) and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific unit is supplied without a magnet. It operates at speeds of 30-500 mm/s and relies on adjustable air cushions at both ends to decelerate the mass smoothly.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX700-75 Is Used
Heavy Assembly Positioning
Dial in the exact 625 to 700 mm end-stop for large component placement without physically swapping out long-stroke cylinders.
Product Changeover
Quickly adapt the retract position during line changeovers to accommodate different large product sizes on the same conveyor.
Press Buffering
Use the heavy 15708 N push force and adjustable rear stopper to fine-tune the bottoming position of large industrial pressing operations.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX700-75 the Right Cylinder?
Choose the 200 mm bore when 15080 N of pull force at 0.5 MPa is required for moving heavy assemblies; if your load is lighter, stepping down to a 160 mm bore provides 9425 N of pull, while the 200 mm bore maxes out at 3204 kgf at 1.0 MPa. The SAIJ200X700-75 is selected over a fixed-stroke SAI when a machine requires variable end-stops or precise fine-tuning during product changeover. Because the nominal stroke is 700 mm, an external guide is highly recommended to support the rod and prevent excessive side-loading over this long travel distance. The rear adjuster acts strictly as a travel stop for end-position tuning and does not hold the load without live air pressure; for true fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder instead. As a dimensionally interchangeable ISO 15552 cylinder, replacements require matching the 200 mm bore, 700 mm stroke, 75 mm adjustment, G3/4 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).

- ✓ 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 SAIJ200AX700-75 FAQ
At 0.5 MPa operating pressure, the SAIJ200X700-75 generates 15708 N of push force and 15080 N of pull force. At its maximum rated pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjuster screw lets you shorten the 700 mm nominal stroke by up to 75 mm, providing an effective travel window of 625 to 700 mm. This stopper decelerates the travel end for fine-tuning at commissioning but does not lock or hold the load without continuous air pressure.
