About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX550-100
The AirTAC SAIJ160X550-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to trim the 550 mm nominal travel back by up to 100 mm for a precise 450-550 mm usable window. Built with an extruded aluminum barrel, it delivers massive thrust—up to 18095 N push at 0.9 MPa—making it suitable for heavy-duty press and lift operations.
This configuration features a robust 40 mm SUS420J2 stainless steel rod (material code A) paired with a PT G3/4 tapered port. The oversized rod thread handles high side loads well, though at 550 mm of stroke, an external guide is still recommended to prevent premature seal wear. It operates at 30-500 mm/s and includes adjustable air cushions at both ends to decelerate heavy masses smoothly.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX550-100 Is Used
Heavy-Duty Press Tuning
Fine-tune the exact bottoming position of a 550 mm stroke press cycle within a 450-550 mm window to accommodate different material thicknesses without changing tooling.
Product Changeover Stops
Adjust the rear stopper on the fly when a packaging line switches to a larger carton size, saving minutes of downtime per shift by avoiding mechanical stop swaps.
Large Assembly Setback
Dial back the full stroke by up to 100 mm during machine commissioning to perfectly align a heavy 18095 N clamping action with a new fixture.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX550-100 the Right Cylinder?
Choose this 160 mm bore when a 100 mm bore (providing 7068 N push at 0.9 MPa) lacks the power to move your load, but a 200 mm bore is physically too large for the machine envelope. The 100 mm adjustment range is ideal for production lines running mixed product sizes, letting operators dial in the exact end position during changeover without swapping the cylinder or adding external stops.
Because the rear adjuster acts strictly as a travel stop and the air cushions only manage deceleration, this cylinder will not hold a load without continuous live air. For fail-safe load holding, integrate an external pilot-operated check valve or select the AirTAC SAIL pneumatic lock series. To match this ISO 15552 footprint exactly, specify a 160 mm bore, 550 mm stroke, PT G3/4 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAIJ160AX550-100 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder generates 18095 N of push force and 14074 N of pull force. At the maximum 1.0 MPa pressure, it achieves a push force of 10053 N and a pull force of 9425 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the nominal 550 mm down to 450 mm. This provides a 100 mm tuning window for commissioning, but it does not lock the load in place without live air pressure.
