About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX280-40
The AirTAC SAIJ160X280-40 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It provides a 240-280 mm usable travel window, allowing you to dial back the 280 mm nominal stroke by up to 40 mm during commissioning without adding external stops. Built with a SUS304 stainless steel rod, it delivers a robust 14074 N push force at 0.7 MPa.
This extruded aluminum profile cylinder includes variable air cushions at both ends to decelerate heavy loads safely. The rear adjuster acts only as a travel stop and does not hold the load without live air pressure. It operates at 30-500 mm/s and uses a PT G3/4 port.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX280-40 Is Used
Heavy Press Tuning
Dial in the exact 240-280 mm end-stop during machine setup to accommodate varying material thicknesses without swapping cylinders.
Product Changeover
Quickly adjust the retract position on a packaging line when transitioning between different package sizes.
Large Assembly Stops
Use the robust 14074 N push force to move heavy components into place while fine-tuning the final resting position.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX280-40 the Right Cylinder?
Select this 160 mm bore when an application requires high thrust (14074 N push at 0.7 MPa) but needs exact end-position tuning for product changeovers. If you need less force, stepping down to a 100 mm bore yields 5497 N push at 0.7 MPa. Choose this adjustable-stroke SAIJ over a fixed SAI when a 240-280 mm travel window is required; otherwise, a fixed stroke is simpler.
Because the 280 mm stroke exceeds 300 mm? No, but heavy moving masses still require an external guide to prevent side-load damage. To replace an ISO 15552 cylinder, match the 160 mm bore, 280 mm stroke, 40 mm adjust, PT G3/4 port, and desired mounting. Note that SAIJ omits FB, CA, CB, and CR mounts, offering only Basic, FA, LB, TC, FTC, TCM1, and TCM2. For load-holding without live air, use an external rod lock or pilot-operated check valve, as the adjuster is not a brake.
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 SAIJ160BX280-40 FAQ
At 0.7 MPa, this 160 mm bore cylinder provides 14074 N of push force and 9425 N of pull force. It can reach a maximum push force of 18095 N at 0.9 MPa.
The rear adjusting screw lets you shorten the 280 mm nominal stroke by up to 40 mm, creating a 240-280 mm usable travel window. The adjuster is a mechanical stop, not a lock, so it cannot hold the load without continuous air pressure.
