About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX950-30
The AirTAC SAIJ100X950-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits fine-tuning of the retract end-position. It provides a usable travel window of 920-950 mm, allowing you to dial back the nominal 950 mm stroke by up to 30 mm during commissioning without adding external stops. It delivers substantial thrust, generating 3927N at 0.5 MPa and reaching 7068N at 0.9 MPa.
This variant features a SUS420J2 stainless steel rod for enhanced corrosion resistance and uses a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. With a 25 mm rod diameter and M20x1.5 thread, it handles robust loads, though the lengthy 950 mm stroke necessitates an external guide to prevent excessive side-loading on the rod.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX950-30 Is Used
Machine Setup & Changeover
Fine-tune the 920-950 mm retract position during machine setup or product size transitions without swapping cylinders or repositioning hard stops.
Variable End-Stop Positioning
Dial in the exact end-of-stroke contact point on long-stroke conveyor diverter arms or pusher plates to accommodate varying package sizes.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX950-30 the Right Cylinder?
The adjustable stroke is ideal for product changeovers where exact end-of-stroke positioning varies by up to 30 mm, unlike a fixed SAI cylinder. When matching ISO 15552 dimensions, specify the 100 mm bore, 950 mm stroke, 30 mm adjustment, PT port, and your required mounting from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is 950 mm, an external guide rail is strongly recommended to manage side loads and prevent rod deflection. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an external rod lock or the AirTAC BSAI clamp-lock series.
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 SAIJ100AX950-30 FAQ
The pull force at 0.5 MPa is 3681N.
The rear adjuster screw lets you shorten the effective stroke within a 920-950 mm window. It acts as a mechanical stop to tune the end position at commissioning, but it is not a lock and will not hold the load without live air pressure.
