About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X950-100
The AirTAC SAIJ100X950-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a generous 850 to 950 mm usable travel window, allowing you to dial back the nominal 950 mm stroke by up to 100 mm during machine commissioning. Delivering 7068 N of push force at 0.9 MPa, it handles heavy positioning tasks with ease.
This 100 mm bore unit uses a G1/2 port and a 25 mm carbon steel rod with an M20x1.5 thread. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches. The rear stopper sets the travel end and deceleration, but it does not lock the load; use a SAIL or BSAI cylinder for true load-holding without live air.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X950-100 Is Used
Product Changeover Lines
Quickly dial the travel end back by up to 100 mm to accommodate varying package lengths on a packaging conveyor without changing the cylinder mounting.
Press Fine-Tuning
Adjust the 850-950 mm stroke window during commissioning to set the exact bottoming position for a 7068 N pressing operation, avoiding mechanical hard stops.
Long-Stroke Material Handling
Move heavy pallets or transfer carts on a 950 mm stroke, using the rear adjuster to sync the final resting position with downstream machinery.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X950-100 the Right Cylinder?
Choose this 100 mm bore when the 80 mm class (4523 N push at 0.9 MPa) lacks the thrust for your tooling, but a 125 mm bore is oversized. The 100 mm adjuster is ideal for product changeovers where end-of-stroke positions vary by up to 100 mm, eliminating the need to swap cylinders or bolt on external stops. Because the 950 mm stroke is long, an external guide is recommended to manage side loads and prevent rod deflection.
To match this ISO 15552 replacement exactly, specify the 100 mm bore, 950 mm nominal stroke, 100 mm adjustment range, PT tapered G1/2 port, and standard carbon steel rod without a magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets.
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 SAIJ100X950-100 FAQ
A rear external screw acts as a mechanical stopper, allowing you to shorten the effective travel from 950 mm down to 850 mm. This provides a 100 mm tuning window for end-position setup without replacing the cylinder.
At 0.9 MPa operating pressure, this 100 mm bore cylinder generates 7068 N of push force and 3681 N of pull force. At the maximum 1.0 MPa, it delivers up to 801 kgf.
