About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX850-75S
The AirTAC SAIJ100X850-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to fine-tune the effective travel anywhere within a 775 to 850 mm window. The extruded aluminum barrel includes sensor grooves on both sides, and this -S variant includes a magnet for position detection.
This model utilizes a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance in humid environments. It features PT tapered port threads (G1/2) and operates at speeds between 30 and 800 mm/s. The rear adjuster acts purely as a mechanical stop to set the end position during commissioning; it does not lock the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series.

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 SAIJ100AX850-75S Is Used
Variable End-Stop Conveying
Dial in the exact 775 to 850 mm push distance to index pallets of varying widths without repositioning the cylinder mount.
Machine Changeover Tuning
Quickly adjust the retract stop during product size transitions to set new end positions on the fly without swapping hardware.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX850-75S the Right Cylinder?
An adjustable-stroke cylinder is selected over a fixed-stroke SAI when you need variable end-stops for machine changeover or precise product-size tuning without physically swapping the actuator. When replacing an ISO 15552 cylinder, match the 100 mm bore, 850 mm stroke, 75 mm adjustment, PT ports, and -S magnet.
Because the stroke is 850 mm, the 25 mm rod and M20x1.5 rod thread will experience amplified side-loading on unsupported loads. An external guide rail is strongly recommended to prevent binding over this long travel distance. The mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR brackets.
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 SAIJ100AX850-75S FAQ
At the maximum 1.0 MPa, the push force reaches 801 kgf.
The rear adjuster screw lets you shorten the nominal 850 mm stroke by up to 75 mm, providing a usable travel window of 775 to 850 mm. The adjuster functions as a mechanical stop and does not hold the load without live air.
