About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-30S
The AirTAC SAIJ160X750-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 720-750 mm, allowing you to dial back the nominal 750 mm stroke by up to 30 mm during commissioning without adding external stops. In this -S configuration, it includes a magnet for CMSE reed and DMSE solid-state sensors.
This large-bore 160 mm unit delivers substantial thrust, generating 14074 N at 0.7 MPa and 18095 N at 0.9 MPa. The rod is constructed from SUS420J2 stainless steel for superior corrosion resistance, and the extruded aluminum barrel incorporates sensor grooves on both sides. It operates at speeds of 30-500 mm/s and uses PT tapered G3/4 ports.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-30S Is Used
Heavy Press Tuning
Fine-tune the 720-750 mm travel window during heavy press commissioning to achieve exact material contact without swapping cylinders.
Product Size Changeover
Adjust the end-stop on automated lines handling varying product lengths, using the 30 mm adjustment range to quickly match new dimensions.
Large Assembly Jigs
Leverage the 18095 N thrust at 0.9 MPa and SUS420J2 stainless rod to actuate large-scale assembly tooling safely.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-30S the Right Cylinder?
Choose this adjustable-stroke model when your machine setup requires precise end-position tuning or product changeover flexibility. Unlike a fixed-stroke SAI cylinder, the rear adjuster screw lets you fine-tune the retract position on the fly. If you need less force, stepping down to a 125 mm bore yields 8590 N at 0.7 MPa, while moving up to a 200 mm bore provides 21991 N at 0.7 MPa.
Because the stroke is 750 mm, the long unsupported piston rod requires an external guide to prevent excessive side-load wear. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for true load-holding, consider an external rod lock or the AirTAC SAIL series. This cylinder is dimensionally interchangeable per ISO 15552 and supports mounting options Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ160AX750-30S FAQ
At 0.7 MPa, this 160 mm bore cylinder provides a push force of 14074 N. At the maximum operating pressure of 1.0 MPa, it delivers up to 2050 kgf.
The rear adjuster acts as a mechanical stop that trims the effective stroke. For this model, it creates a usable travel window of 720 to 750 mm, allowing precise end-position tuning without changing the cylinder.
