About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-40S
The AirTAC SAIJ160X230-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling you to dial back the nominal 230 mm stroke by up to 40 mm. This yields a usable travel window of 190 to 230 mm, allowing precise end-position tuning at commissioning without swapping the barrel or adding external stops. Operating at 0.7 MPa, it delivers 14074 N of push force and 9425 N of pull force.
Built with a SUS304 stainless steel rod for superior corrosion resistance, this unit features PT tapered ports and a magnet for position sensing. It supports AirTAC CMSE reed and DMSE solid-state switches fitted into the dual-side sensor grooves on the extruded aluminum barrel. The rear adjuster acts strictly as a travel stop and deceleration point, meaning it will not hold a load dynamically without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-40S Is Used
Product Size Changeovers
Dial in the 190-230 mm travel window on the fly to accommodate varying package lengths on a packaging line without changing the cylinder.
Heavy Pressing Operations
Leverage the 14074 N push force at 0.7 MPa for heavy pressing or forming tasks, using the rear stop to fine-tune the exact contact depth.
Machine Setup Calibration
Use the 40 mm adjustment range during initial commissioning to perfectly align heavy tooling stops, avoiding the need to machine custom external spacers.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX230-40S the Right Cylinder?
Select this 160 mm bore when an application requires heavy thrust up to 14074 N at 0.7 MPa alongside variable end-stop positioning, such as accommodating product size changes on a line. If you need less force, stepping down to a 100 mm bore yields 5497 N, whereas a 200 mm bore provides 21991 N for heavier loads. Because this is a 230 mm stroke, the 40 mm solid M36x2 piston rod handles high side loads, but any long unsupported overhang still requires an external guide to prevent rod wear. For load-holding without continuous air pressure, this plain SAIJ is insufficient; consider the SAIL air-released lock or BSAI clamp-lock variants instead.
ISO 15552 interchangeability ensures the mounting footprint matches standard cylinders. This specific SKU is configured with a -S magnet, PT ports, and a SUS304 (code B) rod. It supports a reduced mounting accessory set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. The operating speed is 30-500 mm/s, and the variable air cushions at both ends are 50 mm long to absorb kinetic energy.

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 SAIJ160BX230-40S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates a push force of 14074 N and a pull force of 9425 N. It can reach a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster allows you to shorten the effective travel from the nominal 230 mm down to 190 mm, creating a 40 mm adjustable window. This stopper sets the end position but does not lock the load; live air pressure is required to hold position.
