About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX275-75
The AirTAC SAIJ160X275-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 275 mm travel by up to 75 mm for a precise 200-275 mm usable window. Built with an extruded aluminum barrel, it delivers 10053 N of push force at 0.5 MPa, making it suitable for heavy-duty positioning tasks.
This configuration features a SUS304 stainless steel rod for superior corrosion resistance and operates with PT tapered ports. The rear screw acts purely as a travel stop for product changeovers, meaning it cannot hold the load without live air pressure. For load-holding requirements, an external rod lock or the AirTAC SAIL series is required.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX275-75 Is Used
Heavy-Duty Forming
Dial in the exact 200-275 mm retract position for pressing or forming varied material thicknesses without retooling the entire fixture.
Product Changeover
Adjust the end stop on the fly during packaging line size changeovers, utilizing the 75 mm trim range to accommodate different carton depths.
Machine Setup
Fine-tune the retract end position during initial commissioning to perfectly align heavy 14074 N loads at 0.7 MPa without external shims.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX275-75 the Right Cylinder?
Select this 160 mm bore cylinder when an application demands high thrust, such as the 14074 N push force generated at 0.7 MPa, combined with variable end-stop positioning. The generous 75 mm adjustment window is ideal for production lines handling multiple product sizes, allowing you to fine-tune the retract position at commissioning without swapping out the cylinder or adding external mechanical stops. If your force requirements are lower, stepping down to a 125 mm bore yields 6136 N at 0.5 MPa.
Because the 275 mm stroke exceeds the 300 mm threshold, an external guide is recommended to support the rod and prevent excessive side-loading. This model omits the -S magnet, so position sensing is not available out of the box. It utilizes a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.
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 SAIJ160BX275-75 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 75 mm, creating a usable travel window of 200 to 275 mm. This stopper sets the end position but does not lock the load without continuous air pressure.
At 0.5 MPa, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At 0.7 MPa, the push force increases to 14074 N.
