About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X850-10S
The AirTAC SAIJ100X850-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 7068N of push force at 0.9 MPa. It features a carbon steel piston rod and a PT tapered port. An integrated magnet (-S) allows seamless position detection with AirTAC CMSE reed or DMSE electronic solid-state switches.
This model provides an 840-850mm usable travel window, letting you fine-tune the retract end-position by up to 10mm during commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and the variable air cushions at both ends decelerate the heavy 100mm bore load smoothly.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X850-10S Is Used
Precision Machine Setup
Dial in the exact 840-850mm retract position during equipment commissioning to ensure perfect tool alignment without machining custom spacers.
Product Changeover
Quickly adjust the end-stop by a few millimeters on a packaging line when switching to a slightly different carton size, minimizing downtime.
Heavy Material Handling
Leverage the 7068N push force to move heavy pallets or workpieces, using the adjustable end-position to compensate for mechanical wear over time.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X850-10S the Right Cylinder?
Choose this 100mm bore when a smaller 80mm cylinder (providing 4523N push at 0.9 MPa) lacks the necessary thrust. The 10mm adjustable stroke is ideal for dialing in exact end stops during machine setup or product changeovers, which is harder to achieve with a fixed-stroke SAI cylinder. Because the stroke is 850mm, the 25mm rod and M20x1.5 thread handle side loads well, but you must still use an external guide to prevent rod bending over this long travel distance.
When replacing an ISO 15552 cylinder, match the 100mm bore, 850mm stroke, 10mm adjustment, PT port, and mounting choice (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pressure, use an external rod lock or a SAIL/BSAI cylinder.
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 SAIJ100X850-10S FAQ
At an operating pressure of 0.9 MPa, this 100mm bore cylinder provides a push force of 7068N and a pull force of 3681N. At 0.5 MPa, the push force is 3927N.
The rear adjuster screw allows you to shorten the 850mm nominal stroke by up to 10mm, creating an 840-850mm usable travel window. It acts as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
