About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X220-50S
The AirTAC SAIJ80X220-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers a robust 3518N push force at 0.7 MPa and provides a usable travel window of 170 to 220 mm, letting you trim the nominal 220 mm stroke by up to 50 mm during machine commissioning.
This unit includes a magnet for position sensing with AirTAC CMSE reed or DMSE electronic switches. It uses a standard carbon steel rod and a PT tapered port. The adjuster acts purely as a travel stop for end-position tuning, so it will not hold a load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X220-50S Is Used
Machine Changeover
Dial in the exact retract end-stop during product size changes without physically swapping cylinders or reworking fixture stops.
Assembly Calibration
Fine-tune the 170 to 220 mm travel window on the fly to perfect pressing or clamping positions during initial equipment setup.
Variable End-Stop Positioning
Use the rear adjuster screw to set precise retraction limits for multi-format packaging lines requiring flexible travel distances.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X220-50S the Right Cylinder?
Choose this 80 mm bore over the smaller 63 mm bore (which provides 2182N push at 0.7 MPa) when your application demands higher thrust. The adjustable stroke is ideal for product changeovers, allowing you to fine-tune the retract end position without swapping the cylinder or adding external stops. For load-holding without continuous air, consider the SAIL or BSAI series instead.
When matching an ISO 15552 replacement, verify the 80 mm bore, 220 mm nominal stroke, 50 mm adjustment range, PT port thread, and the required -S magnet. The 220 mm stroke is safely within standard limits, but for any travel of 300 mm or more, always use an external guide to prevent rod side-load damage.
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 SAIJ80X220-50S FAQ
At 0.7 MPa operating pressure, this 80 mm bore cylinder provides a push force of 3518N and a pull force of 2268N. It can deliver up to 513 kgf at 1.0 MPa.
The rear adjuster screw allows you to mechanically shorten the effective stroke from the nominal 220 mm down to 170 mm. It acts as a travel stop for end-position tuning and does not lock or hold the load without live air pressure.
