About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X95-75S
The AirTAC SAIJ100X95-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 20-95 mm from its 95 mm nominal stroke. It delivers a robust 3927 N push force at 0.5 MPa, scaling up to 7068 N at 0.9 MPa, making it well-suited for heavy-duty positioning tasks. This variant includes a magnet for CMSE reed and DMSE electronic sensors, and features a standard carbon steel rod with PT tapered ports.
The rear adjustment screw acts purely as a travel stop to fine-tune end positions during commissioning without adding external stops; it is not a lock and will not hold the load without live air pressure. This extruded aluminum profile cylinder supports a speed range of 30-800 mm/s and utilizes a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) that omits FB, CA, CB, and CR options.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X95-75S Is Used
Variable End-Stop Setup
Dial in the exact retract position within the 20-95 mm window during machine commissioning without swapping out physical components.
Product Changeover
Quickly adapt the stroke length on automated lines when handling different product sizes or formats requiring varied travel distances.
Heavy-Duty Positioning
Leverage the 7068 N push force at 0.9 MPa to move substantial masses while precisely tuning the final stopping point via the rear screw.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X95-75S the Right Cylinder?
Select this 100 mm bore cylinder when an application requires substantial thrust combined with highly variable end-stop tuning. If you need less force, the 80 mm bore provides 2513 N push at 0.5 MPa, whereas stepping up to a 125 mm bore yields 6136 N. Choose this adjustable SAIJ model over a fixed-stroke SAI when you need on-the-fly end-position changes during product changeovers. For load-holding without continuous air pressure, this cylinder is insufficient; you must integrate an external rod lock or look into the SAIL or BSAI locking variants instead. Because the nominal stroke is under 300 mm, side-load management is less critical, but the 25 mm rod and M20x1.5 thread handle standard loads effectively.
When specifying a replacement, ensure it matches the 100 mm bore, 95 mm stroke, up to 75 mm adjustment range, PT tapered port threads, and the -S magnet option for sensor compatibility.

- ✓ 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 SAIJ100X95-75S FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw allows you to trim the 95 mm nominal stroke back by up to 75 mm, creating a usable travel window of 20-95 mm. This stopper fine-tunes the end position but does not lock the load without live air pressure.
