About the Airtac SAIJ50 Adjustable Cylinder SAIJ50X170-75S
The AirTAC SAIJ50X170-75-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers 982N of push force at 0.5 MPa and provides a wide usable travel window of 95-170mm, letting you dial back the 170mm nominal stroke by up to 75mm during commissioning.
Equipped with a standard piston magnet, it supports AirTAC CMSE reed and DMSE solid-state sensors via the dual-side barrel grooves. The carbon steel rod and M16x1.5 thread handle standard side loads, while the PT tapered port threads ensure a tight pneumatic seal.

Where the Airtac SAIJ50 Adjustable Cylinder SAIJ50X170-75S Is Used
Machine Changeover
Quickly fine-tune the retract end-position by up to 75mm when switching product sizes on a packaging line, avoiding the need to physically swap cylinders.
Variable End-Stops
Dial in the exact 95 to 170mm travel window during setup to accommodate multi-format tooling without adding external mechanical stops.
Sensor Integration
Leverage the standard magnet and dual sensor grooves to mount CMSE reed or DMSE solid-state switches for precise position feedback.
Is the Airtac SAIJ50 Adjustable Cylinder SAIJ50X170-75S the Right Cylinder?
Choose this 50mm bore when an application requires precise end-position tuning without swapping cylinders or adding external stops. If you need less force, the 40mm bore offers 628N push at 0.5 MPa; for heavier loads, the 63mm bore provides 1559N. This SAIJ model is dimensionally interchangeable per ISO 15552, configured with a 170mm stroke, 75mm adjustment, PT ports, and a magnet for sensors.
For strokes of 170mm, the M16x1.5 carbon steel rod handles moderate side loads, but long unsupported travel still requires an external guide. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ50X170-75S FAQ
At 0.5 MPa, this 50mm bore cylinder provides 982N of push force and 825N of pull force. At the maximum operating pressure of 1.0 MPa, it can deliver up to 200 kgf.
The rear adjuster screw allows you to mechanically shorten the effective travel from the 170mm nominal stroke down to 95mm. It acts as a physical stop to fine-tune the retract end position and does not lock the load without live air pressure.
