About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X160-40S
The AirTAC SAIJ80X160-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 2513N of push thrust at 0.5MPa. Its integrated -S magnet works seamlessly with CMSE reed and DMSE electronic sensors housed in the dual-side barrel grooves. By turning the rear stopper screw, you can trim the nominal 160mm travel back by up to 40mm, creating a precise 120-160mm usable stroke window for fine-tuning end positions at commissioning.
Unlike fixed-stroke alternatives, this adjustable variant eliminates the need to swap cylinders or bolt on external stops during product changeovers. The 25mm carbon steel rod and M20x1.5 thread provide robust resistance to side loads, while the PT tapered port ensures a reliable, leak-free connection. The rear adjuster acts strictly as a travel stop and cannot hold a load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X160-40S Is Used
Changeover End-Stop Tuning
Dial in the 120-160mm travel window during product size changeovers without swapping the cylinder or adding external mechanical stops.
High-Force Positioning
Leverage 2513N of push force at 0.5MPa to shift heavy fixtures, using the rear screw to set the exact final position.
Automated Clamping
Secure varying part thicknesses on an automated line, adjusting the 40mm stroke range to accommodate different material sizes.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X160-40S the Right Cylinder?
Select this 80mm bore when an application requires higher force than a 63mm cylinder (1402N pull at 0.5MPa) but does not warrant the bulk of a 100mm bore (3927N push at 0.5MPa). The 40mm adjustment range is ideal for setting variable end-stops during machine setup, offering far more commissioning flexibility than a fixed SAI cylinder. To replace an ISO 15552 cylinder, match the 80mm bore, 160mm stroke, 40mm adjustment, PT port, and -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Because the SAIJ80X160-40-S is double-acting, it relies on live air to maintain its position. The rear adjuster and air cushions decelerate the travel end but do not function as a lock or brake. If the application requires true load-holding without continuous air pressure, consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock 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 SAIJ80 Adjustable Cylinder SAIJ80X160-40S FAQ
The rear adjuster screw acts as a mechanical stop that shortens the effective travel. For this model, you can trim the 160mm nominal stroke back by up to 40mm, providing a usable 120-160mm window for precise end-position tuning.
At 0.5MPa operating pressure, it provides 2513N of push force and 2268N of pull force. At 0.9MPa, the push force increases to 4523N.
