About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-75S
The AirTAC SAIJ100X110-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 3927N of push force and 3681N of pull force at 0.5 MPa, utilizing a PT G1/2 port. The integrated adjuster allows you to trim the nominal 110mm stroke back by up to 75mm, creating a highly flexible 35-110mm usable travel window for precise commissioning.
This specific configuration includes an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It also features a magnet (-S) for position sensing, compatible with AirTAC CMSE reed and DMSE electronic solid-state switches mounted in the dual-side sensor grooves. The extruded aluminum barrel design maintains standard ISO 15552 mounting dimensions without relying on external tie-rods.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-75S Is Used
Product Changeover
Dial in the exact end-position for different package sizes on a packaging line by adjusting the rear stopper from 35mm to 110mm without changing hardware.
Machine Setup Tuning
Fine-tune the retract stroke during initial commissioning to dial in the exact clamping distance, preventing over-travel on delicate workpieces.
Variable End-Stop Forming
Adjust the effective stroke dynamically on an assembly press to accommodate varying material thicknesses or forming depths within the 75mm adjustment window.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-75S the Right Cylinder?
Choose this adjustable-stroke model when your machine setup requires variable end-stops or frequent product-size changeovers, allowing you to fine-tune the retract position without swapping the cylinder or adding external stops. If you need less force, stepping down to an 80mm bore yields 2513N of push force at 0.5 MPa; conversely, a 125mm bore provides 6136N for heavier loads. Because this cylinder has a 110mm stroke, side-load risks are minimal, but always ensure the load is guided to protect the 25mm rod thread.
When replacing an ISO 15552 cylinder, match the 100mm bore, 110mm nominal stroke, 75mm adjustment range, PT G1/2 port, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Remember that the rear adjuster acts strictly as a travel stop alongside the air cushion—it does not hold the load without live air. For true pneumatic locking without pressure, consider the SAIL or BSAI series instead.
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 SAIJ100AX110-75S FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.9 MPa, the push force increases to 7068N. The operational speed range is 30-800 mm/s.
The rear adjusting screw acts as a mechanical stop that lets you shorten the effective stroke from the nominal 110mm down to as little as 35mm. This creates a 35-110mm adjustable travel window for precise end-position tuning at commissioning. The adjuster is a stop, not a lock, and does not hold the load without live air pressure.
