About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X120-100
The AirTAC SAIJ32X120-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 20 to 120 mm, allowing you to dial back the nominal stroke by up to 100 mm. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This model uses a carbon steel piston rod with an M10x1.25 thread and a PT tapered port. The rear adjuster acts purely as a mechanical stop to set the end position; it does not lock the load without live air pressure. For position holding, an external rod lock or a SAIL cylinder is required. The integrated air cushions at both ends handle end-of-stroke deceleration.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X120-100 Is Used
Product Changeover
Quickly reconfigure the 20 to 120 mm travel window during packaging line format changes without swapping the physical cylinder.
Machine Setup
Fine-tune the retract end-position at commissioning to dial in exact clamping or ejection distances on new assemblies.
Variable End Stops
Establish precise mechanical stops for testing fixtures where the effective stroke needs to be shortened for different parts.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X120-100 the Right Cylinder?
Choose this 32 mm bore actuator when you need extensive on-machine travel flexibility, as the 100 mm adjustment range allows rapid adaptation for various product sizes. If your application requires higher force, stepping up to the 40 mm bore yields 628 N of push force at 0.5 MPa. Conversely, if you need less force and a shorter fixed stroke, a smaller bore might be a better fit. Since this is a double-acting cylinder, you must maintain live air pressure to hold a load, as the rear stopper is not a brake.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 120 mm nominal stroke, PT port thread, and your required mounting interface. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, but omits FB, CA, CB, and CR brackets. The standard carbon steel rod handles standard side loads, but for long unsupported strokes, an external guide is recommended to prevent rod wear.
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 SAIJ32X120-100 FAQ
It features a rear adjusting screw that lets you shorten the effective travel from the 120 mm nominal stroke down to as little as 20 mm, providing a 100 mm adjustment window without adding external stops.
At 0.5 MPa operating pressure, the SAIJ32X120-100 provides 402 N of push force and 345 N of pull force. It can reach 724 N of push force at 0.9 MPa.
