About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X700-50
The AirTAC SAIJ200X700-50 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 700 mm stroke that can be fine-tuned backward by up to 50 mm, creating a precise 650-700 mm usable travel window. Belonging to the 200 mm bore class, it delivers massive thrust, generating 21991 N of push force at 0.7 MPa and a maximum of 28274 N at 0.9 MPa.
This heavy-duty actuator features a carbon steel rod and a G3/4 PT tapered port. Unlike fixed-stroke alternatives, the integrated rear stopper screw enables exact end-position calibration during commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE or DMSE switches if a magnet is specified later.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X700-50 Is Used
Heavy Press Tuning
Dial in the exact 650-700 mm end-of-stroke position during heavy press commissioning to accommodate material thickness variations without swapping actuators.
Product Changeover
Adjust the rear stopper on the fly during production line changeovers to handle different large-format product sizes quickly and accurately.
Long-Stroke Positioning
Utilize the massive 21991 N push force at 0.7 MPa for moving heavy structural components, relying on the adjuster to set the precise retraction limit.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X700-50 the Right Cylinder?
Selecting this 200 mm bore actuator makes sense when your application requires extreme force along with variable end-stop positioning. If the full 28274 N push force at 0.9 MPa is excessive, stepping down to a 160 mm bore yields 18095 N. Because the stroke is 700 mm, an external guide is strongly recommended to prevent excessive side-loading on the rod. The rear adjuster acts purely as a travel stop and does not hold the load without live air; for fail-safe load holding, consider the SAIL or BSAI series.
When matching this ISO 15552 dimensionally interchangeable cylinder for a replacement, verify the 700 mm stroke, 50 mm adjustment range, G3/4 PT port, and your required mounting style. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets.

- ✓ 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 SAIJ200X700-50 FAQ
At 0.5 MPa it provides 15708 N push and 15080 N pull force. At 0.9 MPa, the push force increases to 28274 N, with a maximum rated force of 3204 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the 700 mm nominal stroke by up to 50 mm, providing a usable travel window of 650-700 mm. It functions as a mechanical stop for end-position tuning and is not a locking device.
