About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-10S
The AirTAC SAIJ160X115-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to fine-tune the effective travel window between 105 and 115 mm without adding external stops. Built with a robust 40 mm carbon steel rod and an M36x2 thread, it handles heavy loads effectively, generating 10053 N of pull force at 0.5 MPa and up to 18095 N at 0.9 MPa.
This unit includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors, which seat cleanly into the dual-side sensor grooves on the extruded aluminum barrel. The PT tapered port thread ensures a tight, reliable pneumatic connection, while the adjustable rear stopper enables precise end-position tuning during commissioning.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-10S Is Used
Heavy Fixture Positioning
Dial in the exact 105-115 mm travel window during machine setup to position heavy machining fixtures precisely without external stopper blocks.
Product Changeover Adjustment
Quickly retune the end-stop on automated lines when switching product sizes, using the 10 mm rear adjuster to accommodate minor length variations.
Assembly Press Tuning
Fine-tune the pressing depth of heavy-duty assembly stations at commissioning, leveraging the 18095 N push force at 0.9 MPa for secure component seating.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X115-10S the Right Cylinder?
Choose this 160 mm bore when you need substantial thrust, such as moving heavy fixtures, but require less travel than a 200 mm bore cylinder would provide. If your application needs less force, stepping down to a 100 mm bore yields 3681 N of pull at 0.5 MPa, making it better suited for lighter conveying tasks.
Selecting the SAIJ adjustable-stroke variant over a fixed SAI cylinder is ideal for machine setups requiring exact end-stop calibration during product changeovers. Remember that the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure; for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder. To replace an ISO 15552 cylinder, match the 160 mm bore, 115 mm stroke, 10 mm adjustment, PT port, and -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ160 Adjustable Cylinder SAIJ160X115-10S FAQ
At 0.5 MPa it provides 10053 N of pull force and 14074 N of push force. At the maximum operating pressure of 1.0 MPa, it delivers up to 2050 kgf.
The rear adjuster acts as an external stopper that lets you shorten the nominal 115 mm stroke by up to 10 mm, creating a usable travel window of 105 to 115 mm for precise end-position tuning.
