About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX950-75S
The AirTAC SAIJ160X950-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 950 mm travel by up to 75 mm. This creates a precise 875-950 mm usable stroke window, ideal for fine-tuning end positions during machine commissioning without swapping out the entire actuator. It delivers substantial thrust, generating 14074 N of push force at 0.7 MPa.
This unit features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a built-in magnet (-S) for use with AirTAC CMSE reed and DMSE electronic solid-state sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the PT tapered port threads match the G3/8 porting standard for this 160 mm bore size.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX950-75S Is Used
Heavy Machinery Setup
Fine-tune the 875-950 mm travel window during heavy equipment commissioning to achieve exact positioning without machining external stoppers.
Product Changeover
Quickly adjust the retract end-position by up to 75 mm on a packaging line to accommodate different product lengths on the fly.
Variable End Stops
Dial in the exact end-of-stroke deceleration point for large automated presses, utilizing the 50 mm cushioning and rear stopper screw.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX950-75S the Right Cylinder?
Selecting this 160 mm bore actuator provides a maximum thrust of 10053 N at 0.5 MPa, offering a robust step up from the 100 mm bore (which provides 5497 N at 0.7 MPa) for heavy-duty positioning. The adjustable stroke is chosen over a fixed-stroke SAI cylinder when application setups require variable end-stops or frequent product changeovers. To match this ISO 15552 dimensionally interchangeable cylinder, specify the 950 mm stroke, 75 mm adjustment, G3/8 PT ports, and the -S magnet.
Because the stroke is 950 mm, the M36x2 rod and piston assembly will experience leverage forces under load; an external guide mechanism is recommended to prevent excessive side-loading. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air—use an external rod lock or pilot-operated check valve for fail-safe load holding.
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 SAIJ160AX950-75S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates a push force of 14074 N and a pull force of 9425 N. The maximum thrust at 1.0 MPa is 2050 kgf.
The rear adjuster screw allows you to shorten the effective travel from the nominal 950 mm down to 875 mm. This stopper fine-tunes the end position but does not lock the load without continuous air pressure.
