About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X125-10
The AirTAC SAIJ80X125-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers 2513N of push force at 0.5MPa and uses a G3/8 port. The built-in rear stopper allows you to trim the nominal 125mm stroke back by up to 10mm, providing a precise 115-125mm usable travel window for fine-tuning end positions during machine commissioning.
This 80mm bore actuator features a 25mm carbon steel rod with an M20x1.5 thread, offering robust resistance to side loads. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB and rear pivot options.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X125-10 Is Used
Product Changeover
Dial in the 115-125mm travel window on the fly to accommodate slight length variations when switching between product sizes on a packaging line.
Commissioning Calibration
Fine-tune the retract end-position during initial machine setup, avoiding the need to add external mechanical stops or spacer shims.
Assembly Pressing
Apply up to 2513N of thrust at 0.5MPa for pressing operations while retaining the ability to adjust the stroke depth for different component heights.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X125-10 the Right Cylinder?
Choose this adjustable-stroke model when your setup requires variable end-stops or product changeover flexibility without physically swapping the cylinder. If you need less force, stepping down to a 63mm bore yields 1559N at 0.5MPa; stepping up to a 100mm bore provides 3927N. The rear adjuster acts purely as a travel stop and does not hold the load without live air—if static holding is required, consider the SAIL or BSAI series. To match this ISO 15552 footprint, specify an 80mm bore, 125mm stroke, 10mm adjustment, PT tapered port threads, and no magnet.
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 SAIJ80 Adjustable Cylinder SAIJ80X125-10 FAQ
The rear of the cylinder features an external adjusting screw that acts as a stopper. It allows you to shorten the effective stroke by up to 10mm from the nominal 125mm, giving an adjustable travel window of 115-125mm without changing the cylinder itself.
At 0.5MPa operating pressure, it provides 2513N of push force and 2268N of pull force. The operational speed range for this 80mm bore is 30-800mm/s.
