About the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-75S
The AirTAC SAIJ63X160-75-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that allows you to trim the effective travel by up to 75 mm. This creates a usable stroke window of 85 to 160 mm, letting you fine-tune the retract end-position precisely during commissioning without adding external stops. It delivers a robust 1559 N push force at 0.5 MPa, making it well-suited for mid-range industrial handling.
This variant is equipped with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a piston magnet (-S) for position sensing. The integrated sensor grooves on both sides of the extruded aluminum barrel accept AirTAC CMSE reed and DMSE solid-state switches. The rear adjuster acts purely as a mechanical stop to set the travel end, so it does not hold the load without live air pressure; for fail-safe load holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-75S Is Used
Machine Changeover
Dial in the retract distance from 85 to 160 mm during product size changes on a packaging line without swapping the cylinder.
End-Position Tuning
Fine-tune the exact retract end-stop during initial commissioning to perfect the seating force of a 1559 N assembly press.
Variable End Stops
Adjust the travel window on the fly for testing different sensor trigger points using DMSE solid-state switches.
Is the Airtac SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-75S the Right Cylinder?
Choose this 63 mm bore when your application requires the 1559 N push force at 0.5 MPa, stepping up from a 50 mm bore that provides 982 N. The adjustable stroke is ideal for machine changeovers where the exact retract distance varies by product size, replacing the need to physically swap out a fixed-stroke SAI cylinder. The PT tapered port and G3/8 thread size match the standard 63 mm bore configuration.
When ordering, confirm the ISO 15552 mounting interface (Basic, FA, LB, TC, FTC, TCM1, TCM2) required for your setup. Note that the SAIJ series omits the FB, CA, CB, and CR mounts. Since the 160 mm stroke is under the 300 mm threshold, side-load concerns are minimal, but an external guide is still recommended for heavy lateral loads. For position feedback, pair the internal magnet with CMSE or DMSE sensors.

- ✓ 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 SAIJ63 Adjustable Stroke Air Cylinder SAIJ63AX160-75S FAQ
The cylinder has a 160 mm nominal stroke, but the rear adjuster allows you to shorten the effective travel by up to 75 mm, providing an adjustable usable stroke window of 85 to 160 mm.
At 0.5 MPa, the 63 mm bore provides 1559 N of push force and 1402 N of pull force. It can deliver up to 2805 N push force at the maximum operating pressure of 0.9 MPa.
