About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX40-10
The AirTAC SAIJ160X40-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty operations. With a nominal 40 mm stroke and a 10 mm adjustment range, it provides a usable travel window of 30 to 40 mm. This specific configuration is built with a SUS304 stainless steel rod (code B) and features PT tapered ports, making it highly suitable for environments demanding superior corrosion resistance.
Operating at 0.7 MPa, this 160 mm bore generates 14074 N of push force and 9425 N of pull force. The rear stopper allows you to fine-tune the end position at commissioning without adding external stops, while the extruded aluminum barrel retains standard sensor grooves on both sides for flexible switch placement.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX40-10 Is Used
Heavy Press Tuning
Dial in the exact 30-40 mm travel end-stop during heavy press commissioning to accommodate varying material thicknesses without swapping actuators.
Product Changeover
Quickly adjust the stroke window on automated lines when switching product sizes, using the rear screw to set the precise retraction point.
Corrosive Assembly
Leverage the SUS304 stainless steel rod for high-force clamping and positioning tasks in environments where moisture or corrosive elements are present.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX40-10 the Right Cylinder?
Select this 160 mm bore when an 80 mm bore (providing 3518 N push at 0.7 MPa) cannot meet your force requirements, but step up carefully due to the substantial air consumption. The adjustable 30-40 mm window is ideal for applications requiring precise end-position tuning during machine setup or product changeovers, replacing the need for fixed-stroke SAI cylinders when exact travel must be dialed in on-site. To match this cylinder for an ISO 15552 replacement, verify the 40 mm stroke, 10 mm adjustment, PT port thread, and mounting style.
Because the stroke is under 300 mm, side-load stress is minimized, though the robust 40 mm rod and M36x2 thread naturally handle high mechanical loads. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding without pneumatic pressure, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ160BX40-10 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 achieve a maximum push force of 18095 N at 0.9 MPa.
The SAIJ160X40-10 has a nominal stroke of 40 mm with a 10 mm adjustment range, creating a usable travel window of 30 to 40 mm. The rear adjuster screw acts as a mechanical stop to fine-tune the end position, but it is not a lock and cannot hold the load without continuous air pressure.
