About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X220-10
The AirTAC SAIJ80X220-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 210-220 mm usable travel window, allowing you to dial in the exact retract position during commissioning without swapping components. Delivering 2513 N of push force at 0.5 MPa, it handles demanding positioning tasks with precision.
This model uses a robust 25 mm carbon steel rod and an M20x1.5 thread, which together provide excellent resistance to bending under heavy loads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE solid-state switches. Its mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting FB, CA, CB, and CR configurations.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X220-10 Is Used
Machine Changeover
Fine-tune the retract end-stop within the 210-220 mm window during product size transitions without adding physical shims.
End-Position Trimming
Dial in the exact retract position during commissioning to compensate for mechanical wear or sensor variance.
Variable End Stops
Set precise physical limits for tooling depth on automated lines using the rear adjuster screw.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X220-10 the Right Cylinder?
Choose this 80 mm bore when a 50 mm bore's 982 N pull at 0.5 MPa is insufficient, but a 100 mm bore's 3927 N push is excessive. The 10 mm rear adjuster screw acts purely as a travel stop to fine-tune the end position; it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead. To match this ISO 15552 replacement, specify the 220 mm stroke, 10 mm adjustment, PT G3/8 port, and your preferred mounting bracket. Because the stroke exceeds 300 mm only on larger frames, this 220 mm unit does not require an external guide for standard loads.
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 SAIJ80X220-10 FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers up to 513 kgf.
The rear adjuster screw lets you shorten the 220 mm nominal stroke by up to 10 mm, creating a 210-220 mm usable travel window. The adjuster functions as a mechanical stop and does not lock the load without continuous air pressure.
