About the Airtac SAIJ125 Adjustable Cylinder SAIJ125X95-30
The AirTAC SAIJ125X95-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 65 to 95 mm, allowing you to dial back the 95 mm nominal stroke by up to 30 mm during commissioning. This 125 mm bore generates 6136 N of push force at 0.5 MPa and 8590 N at 0.7 MPa, making it suited for heavy positioning tasks.
It features a carbon steel piston rod and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches if a magnet is added later. The rear adjuster acts purely as a mechanical stop to set the end position and does not hold the load without live air pressure.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125X95-30 Is Used
Product Size Changeovers
Quickly modify the effective stroke from 95 mm down to 65 mm to accommodate varying package lengths on a packaging line without changing hardware.
Heavy Press Positioning
Leverage the 6136 N push force at 0.5 MPa to move heavy tooling into exact alignment, using the rear screw to dial in the final contact position.
Machine Setup Tuning
Fine-tune the retract end position during initial commissioning to prevent mechanical interference, avoiding the need to fabricate external spacers.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125X95-30 the Right Cylinder?
Select this 125 mm bore when a smaller 100 mm bore cannot supply enough thrust, as the 100 mm version yields only 3927 N of push force at 0.5 MPa compared to the 6136 N available here. The adjustable stroke is ideal for production lines running multiple product sizes, letting operators fine-tune the end position without swapping the cylinder or adding external stops. For applications requiring the cylinder to hold a load safely without continuous air pressure, use an AirTAC SAIL pilot-lock or BSAI clamp-lock cylinder instead of relying on the rear stopper. To replace an ISO 15552 cylinder, match the 125 mm bore, 95 mm stroke, 30 mm adjustment, PT G1/2 port, and your required mounting hardware.
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 SAIJ125 Adjustable Cylinder SAIJ125X95-30 FAQ
The rear adjuster screw lets you shorten the effective travel from the 95 mm nominal stroke down to 65 mm. This provides a 30 mm tuning window to set the exact retract end position without replacing the cylinder.
At 0.5 MPa operating pressure, it provides 6136 N of push force and 5734 N of pull force. At 0.7 MPa, the push force increases to 8590 N.
