About the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX160-75S
The AirTAC SAIJ50X160-75-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 85-160 mm, allowing you to dial back the nominal 160 mm stroke by up to 75 mm during commissioning. It delivers a robust 982 N of push force at 0.5 MPa, making it well-suited for moderate-load positioning tasks.
This variant includes a piston magnet for use with AirTAC CMSE reed and DMSE electronic sensors, which mount directly into the extruded aluminum barrel's dual sensor grooves. The piston rod is built from SUS420J2 stainless steel, offering enhanced corrosion resistance compared to standard carbon steel, while the PT tapered port threads ensure a tight pneumatic connection.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX160-75S Is Used
Machine Setup & Commissioning
Dial in the exact end-of-stroke position during initial machine build, using the 75 mm adjustment window to perfectly time the motion without machining new hard stops.
Product Size Changeovers
Quickly adapt the cylinder's travel distance on packaging lines when switching between different product sizes, using the rear screw to set the new 85 mm minimum stroke.
Variable End-Stop Positioning
Provide adjustable physical endpoints for testing or assembly fixtures, allowing operators to fine-tune the 160 mm travel limit to match varying workpiece dimensions.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50AX160-75S the Right Cylinder?
Select this 50 mm bore cylinder when an application requires on-the-fly end-position tuning without swapping components or adding external mechanical stops. It outputs 825 N of pull force at 0.5 MPa; if your process needs less force, the 40 mm bore offers 628 N push, while heavier loads require the 63 mm bore providing 1559 N. The rear adjuster acts solely as a travel stop to fine-tune the 85-160 mm window, meaning it cannot hold a load without live air pressure. For true fail-safe load holding, consider the SAIL or BSAI series. As a dimensionally interchangeable ISO 15552 cylinder, matching a replacement requires a 50 mm bore, 160 mm stroke, 75 mm adjustment, PT port, and a magnet for sensors.
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 SAIJ50 Adjustable Cylinder SAIJ50AX160-75S FAQ
At 0.5 MPa operating pressure, this 50 mm bore cylinder generates 982 N of push force and 825 N of pull force. It can output up to 1767 N of push force at the maximum operating pressure of 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that shortens the effective travel. For this model, the 160 mm nominal stroke can be dialed back by up to 75 mm, creating an adjustable usable travel window of 85 to 160 mm without replacing the cylinder.
