About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX950-40
The AirTAC SAIJ100X950-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 950mm nominal stroke with a usable travel window of 910 to 950mm, allowing you to dial back the extend position by up to 40mm during commissioning.
This variant features a SUS420J2 stainless steel rod (option A) for improved corrosion resistance over standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides, ready for electronic DMSE or reed CMSE switches if a magnet is added later. The rear adjuster acts strictly as a travel stop to fine-tune deceleration, not as a lock to hold the load without live air.

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 SAIJ100AX950-40 Is Used
Heavy Press Tuning
Fine-tune the exact bottoming position of a large press over a 910-950mm travel window to accommodate varying material thicknesses without changing tooling.
Product Diversion
Adjust the retract stop on a heavy-duty diverter arm by up to 40mm during product size changeovers on a packaging line.
Machine Setup
Dial in the precise end-of-stroke location during initial machine commissioning, eliminating the need to bolt on physical external stop blocks.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX950-40 the Right Cylinder?
Selecting this 100mm bore cylinder makes sense when your machine requires substantial thrust (3927N at 0.5MPa) but demands exact end-position tuning without machining external stops. If your application needs less force, stepping down to an 80mm bore yields 2513N at 0.5MPa. The SAIJ100X950-40 uses PT tapered port threads and a G1/2 port size.
Because the 950mm stroke is long, the 25mm rod diameter will still experience leverage forces under high side-loading; an external guide rail is recommended to prevent premature seal wear. For load-holding without continuous air pressure, this cylinder is insufficient—you should integrate an external rod lock or select an AirTAC SAIL or BSAI series cylinder. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ100AX950-40 FAQ
At 0.7MPa, the push force increases to 5497N.
The rear adjuster screw lets you shorten the 950mm nominal stroke by up to 40mm, creating a 910-950mm usable travel window. It acts as a mechanical stop for end-position tuning and does not hold the load without live air pressure.
