About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-20S
The AirTAC SAIJ160X105-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the effective travel window down to 85-105 mm without adding external stops. It delivers robust thrust, generating 10053 N of pull force at 0.5 MPa and up to 18095 N at 0.9 MPa. The carbon steel rod features an M36x2 thread, providing a robust interface for high-load attachments.
This unit includes a -S magnet for position sensing, functioning seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches mounted in the dual-side sensor grooves. Fluid supply routes through PT tapered G3/4 ports, while variable air cushions at both ends manage deceleration. Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-20S Is Used
Heavy Press Tuning
Dial in the exact 85-105 mm travel window during machine setup to accommodate varying material thicknesses without physically remounting the actuator.
Product Changeover Stops
Quickly adjust the rear stopper on a packaging line to handle different carton sizes, shifting the end-of-stroke position by up to 20 mm.
Assembly Station Calibration
Fine-tune the clamping end-position on heavy assemblies, using the rear adjuster to compensate for mechanical wear over time.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X105-20S the Right Cylinder?
Select this 160 mm bore cylinder when your application requires heavy push forces up to 14074 N at 0.7 MPa but demands on-the-fly end-position tuning during commissioning or product changeovers. If your process needs less force, stepping down to a 125 mm bore yields 5734 N of pull force at 0.5 MPa, whereas moving up to a 200 mm bore provides 15080 N. The adjustable rear screw provides a distinct advantage over a fixed-stroke SAI cylinder by allowing precise end-stop calibration without physically swapping the unit.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 105 mm nominal stroke, 20 mm adjustment range, PT G3/4 ports, and the -S magnet requirement. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead, as this cylinder lacks a physical lock.
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 SAIJ160 Adjustable Cylinder SAIJ160X105-20S FAQ
The rear adjuster acts as an external stopper that lets you shorten the nominal 105 mm stroke by up to 20 mm, creating a usable travel window of 85-105 mm. It sets the end position but does not lock the load without live air pressure.
At 0.5 MPa, it provides 10053 N of push force and 9425 N of pull force. At 0.9 MPa, the push force increases to 18095 N.
