About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X800-10S
The AirTAC SAIJ100X800-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 790 to 800 mm. It delivers substantial thrust, pushing 5497 N at 0.7 MPa and 7068 N at 0.9 MPa, making it well-suited for heavy-duty positioning tasks. The barrel features an extruded aluminum design with sensor grooves on both sides.
This variant includes a magnetic piston (-S) for position detection via AirTAC CMSE reed or DMSE electronic sensors. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position without adding external stops, though it does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X800-10S Is Used
Heavy Press Fine-Tuning
Dial in the exact 790-800 mm end position during press setup to accommodate material thickness variations without external stopper blocks.
Long-Stroke Diverting
Actuate heavy pallet stops over an 800 mm travel distance, using the 10 mm adjuster to perfectly square the load against a back fence.
Machine Changeover
Rapidly adapt automated machinery to new product sizes by tweaking the retract stroke end, reducing downtime versus physically swapping cylinders.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X800-10S the Right Cylinder?
Choose this 100 mm bore cylinder when an application requires heavy force output—delivering 3927 N push force at 0.5 MPa—stepping up from a 63 mm bore that provides 1559 N. The 10 mm adjustment range is ideal for fine-tuning end positions during machine commissioning or product changeover, offering more setup flexibility than a fixed-stroke SAI cylinder. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead, as the SAIJ adjuster is only a travel stop.
Because the 800 mm stroke is long and unsupported, an external guide is recommended to prevent excessive side loading on the 25 mm carbon steel rod. This model uses a PT tapered G1/2 port and supports ISO 15552 mounting options including Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100 Adjustable Cylinder SAIJ100X800-10S FAQ
At 0.5 MPa, it provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw lets you shorten the 800 mm nominal stroke by up to 10 mm, creating a 790-800 mm travel window. It functions as a mechanical stop for end-position tuning and does not lock the load.
