About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X220-100
The AirTAC SAIJ80X220-100 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a substantial 2513N of push thrust at 0.5 MPa and utilizes a PT tapered G3/8 port. With a nominal 220mm stroke and a 100mm adjustment range, you can dial the effective travel down to a 120mm minimum, creating a 120-220mm usable window for precise end-position tuning.
This wide 100mm trim capacity is ideal for accommodating significant product-size changeovers on a line without physically swapping the cylinder. The 25mm carbon steel rod and M20x1.5 thread provide robust resistance to side loads, while the extruded aluminum barrel includes sensor grooves on both sides. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X220-100 Is Used
Product Changeover
Leverage the 100mm adjustment range to quickly reposition the end stop for different sized components on the same production line.
Machine Setup
Fine-tune the 120-220mm travel window during commissioning to dial in exact retract positions without swapping hardware.
Variable End Stops
Use the rear stopper screw to set precise retract limits for automated assembly processes requiring 2513N of push force.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X220-100 the Right Cylinder?
Choose this 80mm bore when your application requires roughly 2513N of push force at 0.5 MPa or up to 4523N at 0.9 MPa. If you need less force, stepping down to a 63mm bore yields 1559N at 0.5 MPa, whereas a 100mm bore provides 3927N for heavier demands. The 100mm adjustment range is particularly valuable for commissioning machinery that processes varying part sizes, allowing you to fine-tune the retract stop without adding external stops or buying a fixed-stroke SAI cylinder.
Because the nominal stroke is 220mm, an external guide is recommended to prevent excessive side-loading on the rod. Remember that the rear adjuster acts only as a travel stop and the air cushions manage deceleration; neither will hold a load without live air pressure. For true load-holding, consider the SAIL pneumatic lock or BSAI clamp-lock series. This cylinder is dimensionally interchangeable per ISO 15552, featuring a PT port thread and no integrated magnet.
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 SAIJ80X220-100 FAQ
At 0.5 MPa, this 80mm bore cylinder provides 2513N of push thrust and 2268N of pull thrust. At the maximum operating pressure of 1.0 MPa, it delivers up to 4523N of push force.
The rear adjuster screw allows you to shorten the 220mm nominal stroke by up to 100mm, giving a usable travel window of 120-220mm. This stopper only limits the travel end and does not lock the load without live air pressure.
