About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX75-50S
The AirTAC SAIJ160X75-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 25 to 75 mm usable travel window, allowing you to dial back the 75 mm nominal stroke by up to 50 mm during commissioning. Belonging to the 160 mm bore class, it delivers a robust 14074 N push force at 0.7 MPa. This variant includes a SUS420J2 stainless steel rod (code A) for improved corrosion resistance and a PT tapered port thread.
The extruded aluminum barrel incorporates sensor grooves on both sides, and because this unit carries the -S magnet option, it is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts strictly as a travel stop to set the retract end position; it does not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX75-50S Is Used
Heavy Press Toning
Fine-tune the 25-75 mm travel window on heavy assembly presses to accommodate varying material thicknesses without changing the cylinder setup.
Automated Changeover
Rapidly adjust the retract end-stop during production line changeovers to handle different product dimensions using the 50 mm adjustment range.
High-Force Positioning
Leverage the 14074 N push force at 0.7 MPa to move heavy pallets or fixtures, relying on the rear screw to set precise resting positions.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX75-50S the Right Cylinder?
Choose this 160 mm bore when you need heavy thrust—10053 N push at 0.5 MPa—and a highly variable end-stop for product changeovers. If your application requires less force, stepping down to the 125 mm bore yields 8590 N push at 0.7 MPa. An adjustable stroke is favored over a fixed SAI cylinder when you need fine end-position tuning at machine setup without swapping hardware or adding external stops. To match this ISO 15552 replacement exactly, specify the 160 mm bore, 75 mm stroke, 50 mm adjustment, PT port thread, and the -S magnet.
With a 75 mm stroke, side-loading is minimal, but always ensure the M36x2 rod thread and 40 mm rod diameter are properly aligned. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. The operational speed range for this bore is 30-500 mm/s.

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 SAIJ160AX75-50S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder provides a push force of 14074 N and a pull force of 9425 N. It can deliver a maximum push force of 18095 N at 0.9 MPa.
The nominal stroke is 75 mm with a 50 mm adjustment code, creating a usable travel window of 25 to 75 mm. The rear adjuster screw acts as a stop to trim the stroke back during commissioning, but it does not lock the load without live air pressure.
