About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX270-75S
The AirTAC SAIJ160X270-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 10053N push force at 0.5 MPa and features a SUS304 stainless steel rod for superior corrosion resistance. The integrated magnet enables precise position detection using CMSE reed or DMSE electronic sensors.
This model provides a 195 to 270 mm usable travel window, allowing you to trim the effective stroke by up to 75 mm during commissioning. The extruded aluminum barrel includes sensor grooves on both sides, and the PT tapered port ensures a reliable pneumatic connection for heavy-duty applications.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX270-75S Is Used
Heavy Machinery Setup
Dial in the exact 195 to 270 mm end-position during heavy machinery commissioning without adding external stopper blocks.
Product Size Changeovers
Quickly adapt a conveyor sorting arm for varying package sizes by adjusting the rear stopper screw up to 75 mm.
Corrosive Environments
Leverage the SUS304 stainless steel rod for robust actuation in washdown or mildly corrosive factory settings.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX270-75S the Right Cylinder?
Choose this 160 mm bore when you need substantial thrust, such as the 10053N push force at 0.5 MPa, or step down to a 125 mm bore offering 6136N if the load is lighter. The adjustable stroke is perfect for machines requiring variable end-stops during product changeovers, eliminating the need to physically swap out a fixed-stroke SAI cylinder. For matching an ISO 15552 replacement, verify the 270 mm stroke, 75 mm adjustment, PT port, and the -S magnet requirement.
Because the 270 mm stroke is substantial, ensure adequate external guiding to handle side loads, as the 40 mm rod and M36x2 thread carry limits under heavy offset forces. Remember that the rear adjuster acts only as a travel stop, not a lock; if you need to hold a load securely without live air pressure, consider an AirTAC SAIL or BSAI cylinder instead.
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 SAIJ160BX270-75S FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053N of push force and 9425N of pull force. It can reach a maximum push force of 18095N at 0.9 MPa.
The rear adjuster screw allows you to shorten the nominal 270 mm stroke by up to 75 mm, creating a usable travel window of 195 to 270 mm. This stopper fine-tunes the end position but does not lock the load without continuous air pressure.
