About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-100
The AirTAC SAIJ32X750-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 650-750 mm usable travel window. Delivering 402 N of push force at 0.5 MPa, it is built with a SUS420J2 stainless steel rod for corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This model uses an external stopper at the rear to trim the effective stroke by up to 100 mm without adding external stops. The adjuster acts as a travel end-stop for fine-tuning during commissioning; it does not lock the load without live air. It supports a subset of mounts (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-100 Is Used
Variable End-Stop Tuning
Dial in the exact retraction point within the 650-750 mm window during machine setup to accommodate varying material thicknesses without swapping cylinders.
Product Changeover
Quickly adjust the stroke length on automated lines when switching product sizes, using the rear screw to set new end positions on the fly.
Commissioning Calibration
Fine-tune the final end-of-stroke position during initial machine commissioning to perfect timing without adding bulky external mechanical stops.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX750-100 the Right Cylinder?
Choose this 32 mm bore when you need precise end-position tuning during product changeovers rather than a fixed-stroke SAI cylinder. If your application requires greater thrust, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Because the 750 mm stroke is long, the 12 mm rod and M10x1.25 thread still require an external guide to prevent excessive side-loading and rod deflection.
For load-holding without continuous air pressure, note that the rear adjuster and air cushions only decelerate the travel end; they do not function as a brake. Consider an AirTAC SAIL or BSAI cylinder for true locking needs. To match this ISO 15552 replacement, verify the 32 mm bore, 750 mm stroke, 100 mm adjustment, PT G1/8 port, and mounting hardware.

- ✓ 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 SAIJ32AX750-100 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
The rear adjuster allows you to shorten the 750 mm nominal stroke by up to 100 mm, providing a usable travel window of 650 to 750 mm. It acts as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
