About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX280-30
By turning the rear stopper screw, you can fine-tune the effective travel down by up to 30 mm, creating a precise 250-280 mm usable stroke window. This eliminates the need to swap out the entire cylinder when aligning end positions during commissioning or product changeovers.
Built with a SUS304 stainless steel rod for superior corrosion resistance, this 160 mm bore unit operates at speeds of 30-500 mm/s. It features sensor grooves on both sides of the extruded aluminum barrel for flexible switch mounting. The rear adjuster functions strictly as a travel stop to set deceleration and end positions, not as a locking device, meaning live air is required to maintain the rod position.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | — |
| Max (@1.0 MPa) | 1922 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX280-30 Is Used
Heavy Press Tuning
Dial in the exact 250-280 mm end position for heavy pressing tasks without swapping physical components during tooling changes.
Format Changeovers
Adjust the rear stopper screw on the fly to accommodate different product sizes on automated packaging lines.
Machine Commissioning
Fine-tune the travel limit during initial equipment setup to perfectly align heavy mechanical linkages.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX280-30 the Right Cylinder?
The adjustable 250-280 mm travel window is ideal for machinery that requires variable end-stops during setup or format changes, avoiding the rigid fixed stroke of a standard SAI cylinder. To replace an existing ISO 15552 unit, match the 280 mm nominal stroke, PT G3/4 port threads, and the chosen mounting accessory from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Because this model features a 280 mm stroke, ensure adequate external guiding to handle side loads, as the 40 mm diameter SUS304 rod still requires support for long unsupported travels. If the machine needs to hold a load securely without continuous air pressure, integrate an external pilot-operated check valve or select an AirTAC SAIL or BSAI locking cylinder instead of relying on the rear stopper.
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 SAIJ160 Adjustable Cylinder SAIJ160BX280-30 FAQ
At 0.7 MPa, the push force increases to 14074N.
The rear adjuster screw acts as a mechanical stop that allows you to shorten the 280 mm nominal stroke by up to 30 mm, providing a usable travel window of 250-280 mm for precise end-position tuning.
