About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X125-10
The AirTAC SAIJ32X125-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 10 mm. This creates a usable stroke window of 115-125 mm, enabling precise end-position tuning at commissioning without swapping out the cylinder or adding external stops. It delivers 402 N of push thrust at 0.5 MPa, making it suitable for light-duty handling.
This 32 mm bore model uses a G1/8 port and a 12 mm carbon steel rod with an M10x1.25 thread. The extruded aluminum barrel incorporates sensor grooves on both sides for direct mounting of CMSE reed or DMSE solid-state switches. It features variable air cushions at both ends to decelerate the piston, though these cushions and the rear stopper only manage travel end-positioning and do not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X125-10 Is Used
Machine Commissioning
Dial in the exact 115-125 mm travel window during setup to perfect end-of-stroke positioning without machining external stopper blocks.
Product Changeover
Quickly trim the stroke by up to 10 mm on packaging lines when switching to a slightly shorter product variant.
Light Assembly
Utilize the 402 N push force at 0.5 MPa for precise pressing or positioning tasks that require fine end-stop tuning.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X125-10 the Right Cylinder?
Select this adjustable-stroke model when your application requires exact end-stop calibration or frequent product changeovers that need slight travel reductions. If you need higher force, stepping up to the 40 mm bore yields 628 N of push thrust at 0.5 MPa. Because this is a 125 mm stroke, side-loading is minimal, but always ensure the rod thread and load are aligned to prevent premature seal wear. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR foot and pivot brackets.
To match this cylinder for an ISO 15552 replacement, verify the 32 mm bore, 125 mm nominal stroke, 10 mm adjustment range, PT tapered port thread, and the required mounting accessories. For applications that must hold a load mechanically without continuous air pressure, consider the SAIL air-released lock or BSAI clamp-lock cylinders instead of relying on the rear adjuster.
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 Adjustable Cylinder SAIJ32 SAIJ32X125-10 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push thrust and 345 N of pull thrust. It can reach a maximum push force of 724 N at 0.9 MPa.
A rear adjusting screw acts as a mechanical stopper, allowing you to shorten the 125 mm nominal stroke by up to 10 mm, resulting in a 115-125 mm usable travel window. This stopper only sets the end position and does not lock or hold the load without live air pressure.
