About the Airtac Adjustable Cylinder SAIJ32 SAIJ32X115-100
The AirTAC SAIJ32X115-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 15 to 115 mm, allowing you to dial back the nominal 115 mm stroke by up to 100 mm during commissioning. This bore size delivers 402 N of push force at 0.5 MPa and accepts a PT G1/8 port.
Because the adjuster functions strictly as a mechanical stop to set deceleration and end positions, it will not hold a load without live air pressure. For true load-holding, consider the SAIL or BSAI series. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE or DMSE switches if a magnet is added later.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32X115-100 Is Used
Variable End-Stop Tuning
Dial in the exact retract distance between 15 and 115 mm during machine commissioning without swapping out the entire cylinder.
Product Changeover
Quickly adapt to different part sizes on a packaging line by turning the rear adjuster rather than adding external mechanical stops.
Prototype Positioning
Ideal for test fixtures where the optimal stroke length is unknown upfront, letting you fine-tune travel until the kinematics are perfect.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32X115-100 the Right Cylinder?
Select this 32 mm bore unit when your application requires a highly variable end-stop within a compact footprint, delivering 402 N of thrust at 0.5 MPa. If your setup needs less force, stepping down is not an option in the standard SAIJ range, but stepping up to a 40 mm bore yields 628 N. The massive 100 mm adjustment range on this 115 mm stroke makes it perfect for prototyping or product lines that frequently change package sizes.
This cylinder uses a PT G1/8 port and a 12 mm carbon steel rod with an M10x1.25 thread. It supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. It is dimensionally interchangeable per ISO 15552 standards.

- ✓ 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 SAIJ32X115-100 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from 115 mm down to as little as 15 mm, providing a 100 mm tuning window. It only sets the travel end and does not lock the load without continuous air pressure.
At 0.5 MPa it provides 402 N of push force and 345 N of pull force. It can reach up to 724 N of push force at 0.9 MPa, with a maximum operating speed of 800 mm/s.
