About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X110-50S
The AirTAC SAIJ80X110-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 2513 N push force at 0.5 MPa, making it suitable for medium-to-heavy pneumatic tasks. The integrated -S magnet enables position detection using AirTAC CMSE reed or DMSE electronic sensors along the dual-side barrel grooves.
This model features a 110 mm nominal stroke that can be fine-tuned down by up to 50 mm, creating a usable travel window of 60 to 110 mm. The carbon steel rod and PT tapered port are standard, while the rear stopper allows precise end-position tuning during commissioning without requiring external stops. The adjuster acts solely as a travel limit and does not lock the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X110-50S Is Used
Variable End-Stop Positioning
Ideal for assembly lines requiring frequent product size changeovers, utilizing the 60-110 mm travel window to adapt end positions quickly without mechanical rebuilds.
Machine Setup Commissioning
Allows engineers to fine-tune the retract stroke precisely during initial machine commissioning, ensuring perfect alignment without adding bulky external stopper hardware.
Dynamic Material Handling
Provides 2513 N of push force at 0.5 MPa for moving heavier pallets or workpieces, while the rear screw accommodates varying package dimensions on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X110-50S the Right Cylinder?
Choose this 80 mm bore when an application requires higher thrust than a 63 mm cylinder (which provides 1559 N push at 0.5 MPa) but does not need the full 3927 N output of a 100 mm bore. The 50 mm adjustment range is ideal for machinery that frequently handles varying product sizes, allowing operators to dial in the exact end-stop without swapping cylinders. For load-holding without continuous air pressure, an external rod lock or a SAIL/BSAI variant is required, as the rear adjuster only trims travel distance.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 110 mm stroke, 50 mm adjustment, PT port, and -S magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke exceeds 300 mm threshold checks do not apply here, but always ensure external guiding for optimal side-load management.
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 SAIJ80X110-50S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw allows you to shorten the 110 mm nominal stroke by up to 50 mm, providing an adjustable travel window of 60 to 110 mm. It functions as a travel stop and does not hold the load without live air pressure.
