About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X120-10
The AirTAC SAIJ32X120-10 is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, allowing you to fine-tune the end position during commissioning. It provides a usable travel window of 110-120 mm, letting you dial back the 120 mm nominal stroke by up to 10 mm without adding external stops. Delivering 402 N of push force at 0.5 MPa, it suits light-duty positioning.
This extruded aluminum profile barrel features sensor grooves on both sides for CMSE reed or DMSE electronic switches. It uses a 12 mm carbon steel rod with an M10x1.25 thread and PT tapered ports. The mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X120-10 Is Used
Machine Changeover
Quickly trim the 120 mm stroke by up to 10 mm to accommodate new product sizes on a packaging line without swapping the cylinder.
End-Position Tuning
Dial in the exact retract stop during commissioning to compensate for mechanical wear or sensor placement drift.
Light-Assembly Fixtures
Provides 402 N of push force at 0.5 MPa for positioning light components with a customizable 110-120 mm travel window.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X120-10 the Right Cylinder?
Choose this 32 mm bore when an application requires 402 N of push force at 0.5 MPa and exact end-position tuning. If you need less force, dropping to a smaller bore changes the footprint, but stepping up to a 40 mm bore yields 628 N. The adjustable rear stopper is ideal for product changeovers, whereas a fixed SAI cylinder is better for unchanging travel limits.
For replacing an ISO 15552 cylinder, match the 32 mm bore, 120 mm stroke, 10 mm adjuster, PT G1/8 port, and standard carbon steel rod. This model has no magnet, so position sensing requires external stops or a different setup. The rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, use a SAIL or BSAI cylinder.
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 SAIJ32X120-10 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers 82 kgf.
The rear adjuster screw allows you to shorten the 120 mm nominal stroke by up to 10 mm, creating a 110-120 mm usable travel window. The adjuster acts as a mechanical stop to set the end position and does not lock the load without air pressure.
