Airtac SAIJ100 Adjustable Cylinder SAIJ100AX800-40
The AirTAC SAIJ100 Adjustable Cylinder SAIJ100AX800-40 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 800mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX800-40
Its 800mm nominal stroke features an integrated stopper screw that creates a 760-800mm usable travel window, allowing precise end-position tuning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting.
This specific configuration uses a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and pairs with PT tapered port threads. The adjustable stopper acts solely as a travel end deceleration device and does not hold the load without live air pressure. For applications requiring position holding without continuous air, consider the SAIL or BSAI series instead.

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 SAIJ100AX800-40 Is Used
Machine Changeovers
Dial in the exact retract distance during product size changes on a packaging line using the 40mm rear stopper, eliminating the need to physically swap cylinders for different lengths.
Variable End Stops
Fine-tune the retraction end-position during commissioning to perfectly align materials or pallets on a conveyor without installing bulky external mechanical stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX800-40 the Right Cylinder?
The 40mm adjustment range is ideal for product changeovers on a packaging line, letting you dial in the exact retract distance at commissioning rather than swapping a fixed-stroke SAI cylinder. When replacing an ISO 15552 cylinder, match the 800mm stroke, 40mm adjustment, G1/2 port, and your required mounting interface from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2.
Because the stroke is 800mm, the 25mm rod diameter and M20x1.5 rod thread provide robust support, yet an external guide is still recommended to manage side loads over this long unsupported travel. The cylinder operates at speeds of 30-800mm/s and lacks a magnet for sensors, relying on external physical stops for end-position control.
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 SAIJ100AX800-40 FAQ
The rear stopper screw allows you to shorten the effective retract stroke by up to 40mm, creating a usable travel window of 760-800mm. This stopper only sets the travel end and does not lock or hold the load without live air pressure.
