About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X950-10
The AirTAC SAIJ100X950-10 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 5497N of push force at 0.7MPa and features a 950mm nominal stroke that can be fine-tuned down by up to 10mm, creating a precise 940-950mm usable travel window. This adjustability allows you to dial in the exact end position during commissioning without adding external stops.
This model features a standard carbon steel piston rod with an M20x1.5 thread and a G1/2 port. Because the 950mm stroke is long, the robust 25mm rod diameter helps manage side loads, though an external guide is still recommended for unsupported lengths. The extruded aluminum barrel includes sensor grooves on both sides, and adding a magnet allows the use of AirTAC CMSE reed or DMSE electronic solid-state switches.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X950-10 Is Used
Precision End-Position Tuning
Dial in the exact retract distance within a 940-950mm window during machine commissioning to achieve perfect alignment without machining custom spacers.
Product Size Changeovers
Quickly adapt automated line strokes for varying product lengths by turning the rear adjuster, avoiding the need to physically swap out the entire cylinder.
Heavy Load Positioning
Leverage the 5497N push force at 0.7MPa to move substantial payloads, using the fine-tuned end-stop to prevent overtravel damage on long-stroke machinery.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X950-10 the Right Cylinder?
Choose this 100mm bore when you need heavy thrust that a smaller 80mm bore (providing 3518N push at 0.7MPa) cannot supply, but without stepping up to a larger 125mm unit. The adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers, functioning as a travel stop rather than a position lock. If your application requires holding a load without live air pressure, consider an AirTAC SAIL or BSAI cylinder instead. To match this ISO 15552 cylinder for a replacement, verify the 100mm bore, 950mm stroke, 10mm adjustment, G1/2 port, and standard carbon steel rod. For a stroke of 950mm, always ensure adequate external guiding to prevent excessive side-loading on the rod.
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 SAIJ100X950-10 FAQ
At a standard operating pressure of 0.7MPa, this 100mm bore cylinder provides 5497N of push force and 3681N of pull force. It can reach a maximum push force of 7068N at 0.9MPa.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 10mm, providing a usable travel window of 940-950mm. It only sets the travel end and does not lock the load without live air pressure.
