About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X950-100S
The AirTAC SAIJ63X950-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 1559N of pull force at 0.5MPa and features a 950mm nominal stroke that can be dialed back by up to 100mm, creating an 850-950mm usable travel window for precise end-position tuning. The integrated -S magnet allows seamless position detection using AirTAC CMSE reed or DMSE electronic solid-state switches mounted in the dual-side sensor grooves.
This 63mm bore utilizes a G3/8 PT port and an M16x1.5 rod thread. Because the 950mm stroke is long relative to the 20mm rod diameter, external guide rails should be used to prevent excessive side-loading. The rear adjuster acts strictly as a mechanical stop to decelerate the travel end and does not hold the load without live air pressure.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X950-100S Is Used
Variable End-Stop Configuration
Dial in the exact 850-950mm travel distance during machine commissioning to accommodate different material lengths without adding external physical stops.
Product Size Changeover
Quickly adjust the rear stopper on the line when switching between product sizes, reducing downtime and avoiding the need to bolt on new hard stops.
Long-Stroke Positioning
Leverage the 1559N pull force to move heavy loads over a 950mm span while fine-tuning the final resting position to within a 100mm adjustment window.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X950-100S the Right Cylinder?
Choose this adjustable-stroke model when your machine setup requires variable end-stops or product changeover flexibility without physically swapping cylinders. If your application requires less thrust, stepping down to a 50mm bore yields 825N of pull force at 0.5MPa. If you need more power, an 80mm bore provides 2268N. For load-holding without continuous air pressure, a plain SAIJ is insufficient since the rear adjuster is a stop, not a lock; consider an AirTAC SAIL or BSAI cylinder instead.
This SKU serves as a direct ISO 15552 dimensionally interchangeable replacement, configured with a 63mm bore, 950mm stroke, 100mm adjustment, PT tapered port threads, and a magnet for sensors. It supports the SAIJ mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2) but omits FB, CA, CB, and CR brackets. Given the 950mm stroke, supporting the rod to minimize side-load deflection is critical.

- ✓ 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 SAIJ63 Adjustable Stroke Air Cylinder SAIJ63X950-100S FAQ
At 0.5MPa operating pressure, this 63mm bore cylinder provides 1559N of push force and 1402N of pull force. At 0.7MPa, the push force increases to 2182N.
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 100mm. This creates an adjustable travel window between 850mm and 950mm. It only sets the travel end and does not lock the load without live air.
