About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX85-75
The AirTAC SAIJ100X85-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the retract end position. It provides a usable travel window of 10 to 85 mm, letting you dial in the exact stroke length during machine setup without adding external stops.
This SKU is built with an SUS420J2 stainless steel rod for enhanced corrosion resistance compared to standard carbon steel. It uses a PT tapered port thread and omits a magnet, meaning electronic DMSE or reed CMSE sensors cannot be fitted unless specified. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ100AX85-75 Is Used
Variable End-Stop Forming
Dial in the exact retract distance for a forming press, allowing rapid changes between different material thicknesses without physically remounting the actuator.
Machine Setup Commissioning
Fine-tune the 10 to 85 mm travel window during initial commissioning to perfectly time the engagement of downstream components and prevent mechanical crashes.
Product Size Changeover
Adapt a packaging line to different carton sizes by simply rotating the rear adjuster screw to shorten the stroke, eliminating the need to swap out the entire cylinder.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX85-75 the Right Cylinder?
Choose this 100 mm bore when you need high force (3927 N at 0.5 MPa) and a highly flexible end-stop, stepping up from a 63 mm bore that only provides 1559 N. The 75 mm adjustment range is ideal for product changeovers where the required travel varies significantly. Because the rear adjuster acts only as a travel stop and the air cushions handle deceleration, this cylinder cannot hold a load without live air; for dead-end holding, select a SAIL pneumatic lock or BSAI clamp-lock cylinder instead. When matching ISO 15552 dimensions, confirm the 100 mm bore, 85 mm stroke, PT port thread, and the specific mounting bracket required.
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 SAIJ100AX85-75 FAQ
A rear stopper screw lets you trim the effective stroke by up to 75 mm. With an 85 mm nominal stroke, this creates a usable travel window of 10 to 85 mm, adjustable at commissioning without replacing the cylinder.
At 0.9 MPa, the push force increases to 7068 N.
