About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-50S
The AirTAC SAIJ160X750-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 750 mm travel by up to 50 mm. This yields a precise usable travel window of 700 to 750 mm, enabling exact end-position tuning at commissioning without swapping out the physical cylinder. It delivers substantial thrust, generating 10053 N of push force and 9425 N of pull force at a 0.5 MPa operating pressure.
This specific SKU features a SUS420J2 stainless steel rod (code A) for superior corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. Because the 750 mm stroke is long, the 40 mm rod and M36x2 thread still require external guidance to prevent excessive side-loading. The rear adjuster acts purely as a travel stop for deceleration setup, not a lock, so live air is required to hold the load.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-50S Is Used
Variable End-Stop Conveying
Shifts the retract end-position by up to 50 mm to accommodate different pallet sizes without changing the cylinder.
Commissioning Fine-Tune
Dial in the exact 700 to 750 mm travel during machine setup to perfect a process without adding external stops.
Long-Stroke Forming
Provides 10053 N of push force at 0.5 MPa for large-format presses, relying on external guides for the 750 mm span.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-50S the Right Cylinder?
Choose this 160 mm bore when an 80 mm bore falls short of the 2513 N push force available at 0.5 MPa, but a 200 mm bore is unnecessary. The adjustable 700-750 mm window is ideal for product changeovers on a line, letting you shift the end-stop without bolting on external spacers or buying a fixed-stroke SAI cylinder. For load-holding without continuous air pressure, this cylinder's adjuster will not suffice; you should step over to an SAIL air-released lock or BSAI clamp-lock. When matching ISO 15552 replacements, specify the 160 mm bore, 750 mm stroke, 50 mm adjustment, PT tapered G3/4 port, and the -S magnet.
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 SAIJ160AX750-50S FAQ
At 0.5 MPa, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. The operational speed range for this bore size is 30-500 mm/s.
The rear adjuster screw lets you shorten the 750 mm nominal stroke by up to 50 mm, creating a 700-750 mm travel window. It functions as a hard stop for position tuning, not a lock, meaning live air is still needed to hold the load.
