About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X115-75
The AirTAC SAIJ32X115-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 40-115 mm usable travel window, letting you dial back the 115 mm nominal stroke by up to 75 mm during machine setup. Delivering 402 N of push force at 0.5 MPa, it suits lighter-duty tasks requiring exact end-position tuning.
This model uses a 12 mm carbon steel rod with an M10x1.25 thread, offering a compact yet robust interface for standard side loads. The extruded aluminum barrel includes sensor grooves on both sides, ready for AirTAC CMSE or DMSE switches if a magnet is added later. It supports a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X115-75 Is Used
Changeover Setup
Dial in the exact 40-115 mm retract position during machine format changes without installing external physical stops.
End-Stop Trimming
Fine-tune the final end-of-stroke position on assembly pick-and-place units to compensate for mechanical drift.
Variable Product Sorting
Adjust the travel window on the fly for diverting different package sizes on a single pneumatic routing lane.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X115-75 the Right Cylinder?
Choose this 32 mm bore when you need precise retract positioning that a fixed-stroke SAI cannot provide, avoiding the need to swap cylinders during product changeovers. If your application requires greater thrust, stepping up to the 40 mm bore yields 628 N at 0.5 MPa. Conversely, if you need less force, a smaller option would be required.
Configuration details: 32 mm bore, 115 mm stroke, 75 mm adjustment, PT tapered port, carbon steel rod, and no magnet. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider an external rod lock or the SAIL series.
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 SAIJ32X115-75 FAQ
It features a rear adjuster screw that lets you shorten the effective travel from 115 mm down to as little as 40 mm, creating a 75 mm adjustable window without changing the cylinder itself.
At 0.5 MPa, it provides 402 N of push force and 345 N of pull force. It can deliver up to 724 N of push force at 0.9 MPa.
