About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-75
The AirTAC SAIJ100X110-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 110 mm stroke that can be dialed back by up to 75 mm, yielding a precise 35-110 mm usable travel window for on-the-fly end-position tuning. Delivering 3927 N of push force at 0.5 MPa, it is built with an SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads.
This extruded aluminum profile cylinder includes variable air cushions at both ends to manage kinetic energy. The rear adjuster acts purely as a travel stop to fine-tune positioning during commissioning or product changeovers, meaning it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-75 Is Used
Machine Setup Calibration
Dial in the exact 35-110 mm travel distance during initial commissioning to perfectly align pressing or clamping forces without adding external stopper blocks.
Product Changeover
Quickly adjust the retract end-position by up to 75 mm when switching between different product sizes on the same production line.
Variable End Stops
Handle multiple part sizes in automated assembly by fine-tuning the stroke window on the fly, ensuring precise end-of-travel positioning.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-75 the Right Cylinder?
Choose this 100 mm bore when an application requires substantial thrust—3927 N at 0.5 MPa or 7068 N at 0.9 MPa. If your force requirements are lower, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, whereas moving up to a 125 mm bore provides 6136 N. The adjustable stroke is ideal for variable end stops and machine setups where the exact travel distance needs fine-tuning without swapping out a fixed-stroke SAI cylinder.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 110 mm stroke, 75 mm adjustment range, PT port threads, and the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting footprints. Because this unit lacks a magnet (-S), it will not work with CMSE or DMSE sensors; if position feedback is needed, select a -S variant. While the 25 mm rod and M20x1.5 thread handle high side loads well, any stroke over 300 mm would require an external guide, though this 110 mm travel window remains well within safe limits.
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 SAIJ100AX110-75 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 801 kgf.
The rear adjusting screw allows you to shorten the effective stroke by up to 75 mm from the nominal 110 mm, creating a 35-110 mm usable travel window. The adjuster functions as a mechanical stop to fine-tune the end position and does not lock or hold the load without continuous air pressure.
