About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX270-10S
The AirTAC SAIJ160X270-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end position at commissioning. With a nominal stroke of 270 mm and a 10 mm adjustment range, it provides a usable travel window of 260-270 mm without requiring external stops. It delivers a robust push force of 10053 N at 0.5 MPa, making it suitable for heavy-duty positioning tasks.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the PT tapered port threads ensure a tight, reliable pneumatic connection.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX270-10S Is Used
Heavy Press Tuning
Dial in the exact 260-270 mm end position during machine commissioning to accommodate varying material thicknesses without adding external mechanical stops.
Product Changeover
Quickly adjust the rear stopper by up to 10 mm when switching the production line to a different product size, saving downtime on the factory floor.
High-Force Positioning
Leverage the 10053 N push force at 0.5 MPa to move heavy pallets or tooling, using the SUS304 rod in environments where corrosion resistance is required.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX270-10S the Right Cylinder?
Choose this 160 mm bore cylinder when an application requires heavy thrust—10053 N push at 0.5 MPa—and the ability to dial in the exact end-of-stroke position. If you need less force, stepping down to a 125 mm bore yields 6136 N; if you need significantly more power, a 200 mm bore provides 15708 N. The adjustable rear stopper is ideal for machine setups where product sizes frequently change, eliminating the need to physically swap out a fixed-stroke SAI cylinder.
Because the stroke is 270 mm, you should guide the load to prevent excessive side-loading on the rod thread (M36x2). The rear adjuster acts only as a travel stop and cannot hold the load without live air pressure; for fail-safe load holding, consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder. This SAIJ model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is dimensionally interchangeable per ISO 15552.
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 SAIJ160BX270-10S FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder generates a push force of 10053 N and a pull force of 9425 N. At the maximum pressure of 1.0 MPa, it delivers a push force of 18095 N.
The rear adjuster screw allows you to shorten the effective travel from the nominal 270 mm down to 260 mm. This creates a 260-270 mm usable window for fine-tuning the retract end position at commissioning without swapping the cylinder.
