About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX95-30
The AirTAC SAIJ100X95-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers a robust 3927N push force at 0.5MPa, with a nominal 95mm stroke that can be fine-tuned down by up to 30mm, yielding a precise 65-95mm usable travel window for product changeovers.
Equipped with a SUS304 stainless steel rod and PT tapered ports, this extruded aluminum barrel omits heavy tie-rod construction. The rear screw acts purely as a travel stop for end-position tuning and does not lock the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX95-30 Is Used
Variable End-Stop Tuning
Dial in the exact 65 to 95mm end position during machine commissioning without installing external physical stops on the frame.
Product Size Changeovers
Quickly adapt a packaging line to different carton depths by trimming the rear stroke up to 30mm to accommodate new formats.
Heavy Fixture Positioning
Leverage the 3927N push force at 0.5MPa to shift heavy machining fixtures into place while finely tuning the final landing spot.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX95-30 the Right Cylinder?
Choose this 100mm bore when the 50mm class (982N push at 0.5MPa) lacks thrust, providing 3927N to move heavy fixtures. The adjustable 65-95mm window allows exact end-stop tuning without swapping cylinders. For load-holding without live air, select a SAIL or BSAI lock cylinder, as this adjuster is not a brake.
To replace an ISO 15552 cylinder, match the 100mm bore, 95mm stroke, 30mm adjustment, PT G1/2 port, and desired mounting from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, TCM2. Since the 95mm stroke is under 300mm, external side-load guides are less critical than on longer strokes, but the 25mm rod still handles standard lateral stress well.

- ✓ 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 SAIJ100BX95-30 FAQ
At 0.5MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7MPa, the push force increases to 5497N.
The rear adjuster screw allows you to shorten the 95mm nominal stroke by up to 30mm, creating a usable travel window of 65-95mm. It functions as a physical stop for end-position tuning and does not hold the load without air pressure.
