About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX550-30S
The AirTAC SAIJ160X550-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 550 mm travel by up to 30 mm for a precise 520-550 mm usable window. Built with an SUS420J2 stainless steel rod (code A) and a PT tapered port, it delivers massive thrust up to 18095 N at 0.9 MPa. The included magnet (-S) directly supports position sensing via AirTAC CMSE reed or DMSE electronic solid-state switches.
Because the adjuster acts purely as a mechanical stop at the retract end, it cannot hold a load without live air pressure. For load-holding requirements without continuous air, consider an external rod lock or related AirTAC series like SAIL or BSAI. This extruded aluminum profile cylinder omits FB, CA, CB, and CR mounts, utilizing a focused ISO 15552 mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX550-30S Is Used
Heavy Press Tuning
Fine-tune the 520-550 mm retract stop on heavy pressing equipment during initial commissioning to achieve exact material deformation without external shims.
Product Changeover
Rapidly adjust the end-of-stroke position on automated lines when switching between product sizes, using the rear screw to trim up to 30 mm of travel.
Large Fixture Actuation
Actuate massive welding or machining fixtures where the 18095 N thrust at 0.9 MPa is required, using the DMSE sensors to confirm end positions.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX550-30S the Right Cylinder?
Select this 160 mm bore when a 125 mm cylinder (delivering 11045 N push at 0.9 MPa) lacks the force for heavy positioning, but a 200 mm bore (28274 N) would be excessive. The 30 mm adjustment window is perfect for fine-tuning end positions during product changeovers without swapping the cylinder or adding external stops. When specifying an ISO 15552 replacement, match the 550 mm stroke, 30 mm adjust code, PT G3/4 port, and -S magnet.
With a 550 mm stroke, the 40 mm diameter rod and M36x2 thread provide robust support, but an external guide is strongly recommended to prevent excessive side-loading on long unsupported travels. Operating speed for this bore is 30-500 mm/s.
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 SAIJ160AX550-30S FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder provides a push force of 18095 N and a pull force of 9425 N. The maximum push force is 10053 N at 0.5 MPa.
The rear mechanical stopper allows you to shorten the effective 550 mm stroke by up to 30 mm, creating a 520-550 mm travel window. It acts as a travel stop and does not lock the load without continuous air pressure.
