About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X75-10
The AirTAC SAIJ100X75-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 65-75 mm usable travel window from its 75 mm nominal stroke. Delivering 3927 N of push force at 0.5 MPa, it is equipped with a carbon steel piston rod and a G1/2 port. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.
This adjustable model lets you fine-tune the retract end-position at commissioning without adding external stops. The rear screw acts purely as a travel stop for deceleration, not a lock, so live air is required to hold the load. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X75-10 Is Used
Machine Setup Tuning
Dial in the exact 65-75 mm retract position during machine commissioning to perfect end-of-stroke contact without swapping physical hardware.
Product Size Changeover
Quickly adjust the stroke end-stop on automated lines when changing product sizes, using the rear screw to adapt the travel window.
Heavy Forming Stops
Leverage the 3927 N push force at 0.5 MPa for pressing or forming tasks, using the adjustable stop to regulate the exact travel distance.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X75-10 the Right Cylinder?
Choose this 100 mm bore when you need heavy thrust (3927 N at 0.5 MPa) and precise variable end-stop control within a compact 75 mm stroke. If your application requires less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa. The SAIJ100X75-10 is selected over a fixed SAI cylinder when machine setups demand a dialed-in 65-75 mm travel window rather than a rigid stroke.
For ISO 15552 replacement matching, verify the 100 mm bore, 75 mm stroke, 10 mm adjustment, PT tapered port threads, and the required mounting accessory. Since this cylinder lacks a magnet, add the -S suffix if you need position sensing. The 25 mm rod and M20x1.5 thread handle high side loads, though any long unsupported stroke still requires an external guide.
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 SAIJ100X75-10 FAQ
The rear adjuster screw lets you shorten the 75 mm nominal stroke by up to 10 mm, providing a usable travel window of 65-75 mm. It acts as a mechanical stop to set the end position and does not lock the load without live air pressure.
At 0.5 MPa operating pressure, the SAIJ100X75-10 provides 3927 N of push force and 3681 N of pull force. At its maximum 1.0 MPa pressure, it can deliver up to 801 kgf.
