About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X800-100
The AirTAC SAIJ100X800-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits a usable travel window of 700-800mm. Fitted with a G1/2 port and a 25mm carbon steel rod, it delivers a robust 5497N push force at 0.7MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of position feedback.
This adjustable variant allows operators to fine-tune the retract end-position during commissioning without swapping hardware or adding external stops. It supports a speed range of 30-800mm/s and utilizes a variable air cushion at both ends. The rear adjuster acts solely as a travel stop to set deceleration, not as a lock to hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X800-100 Is Used
Product Size Changeovers
Dial in the exact 700-800mm retract position on packaging lines when switching between different carton lengths, eliminating the need to physically swap cylinders.
Machine Setup Tuning
Fine-tune the end-of-stroke stop during initial commissioning to perfectly time a pressing operation, avoiding the cost of machining custom external spacers.
Adjustable Material Pushers
Push varying lengths of material on an assembly line by adjusting the rear stopper screw, accommodating different batch requirements on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X800-100 the Right Cylinder?
Choose this 100mm bore when an 80mm cylinder (providing 3518N push at 0.5MPa) lacks sufficient thrust, but a 125mm bore is unnecessary. The 100mm adjustment code is selected over a fixed-stroke SAI when a machine handles multiple product sizes, requiring a variable end-stop for rapid changeover. To match this ISO 15552 replacement exactly, specify the 800mm stroke, 100mm adjustment, PT tapered port thread, and the required mounting from the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, TCM2.
Because the 800mm stroke is substantial, the 25mm rod and M20x1.5 thread provide rigidity, but an external guide is still recommended to prevent excessive side-loading on the piston. For applications requiring the load to be held mechanically without continuous air pressure, a plain SAIJ is insufficient; consider the SAIL air-released lock or BSAI clamp-lock cylinder instead.
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 SAIJ100X800-100 FAQ
At an operating pressure of 0.7MPa, this 100mm bore cylinder provides a push force of 5497N and a pull force of 3681N. At 0.5MPa, the push force is 3927N.
The rear adjuster screw lets you shorten the nominal 800mm stroke by up to 100mm, creating a usable travel window of 700-800mm. It functions as a mechanical stop to tune the end position and does not lock the load without live air.
