About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX650-75S
The AirTAC SAIJ160X650-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a substantial 14074 N push force at 0.7 MPa and features a 575-650 mm usable travel window, allowing you to dial back the 650 mm nominal stroke by up to 75 mm. The SUS420J2 stainless steel rod offers enhanced corrosion resistance, while the integrated magnet supports CMSE reed and DMSE electronic sensors.
This adjustable-stroke design allows fine end-position tuning at commissioning or during product changeover without swapping the cylinder or adding external stops. The rear adjuster acts as a mechanical stop that sets the travel end alongside the variable air cushions, but it is not a lock and will not hold the load without live air. For load-holding without pressure, consider the SAIL or BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX650-75S Is Used
Variable End-Stop Tuning
Dial in the exact retract position within the 575-650 mm window during machine setup without installing external physical stops.
Product Changeover
Quickly adjust the stroke on automated lines when switching between product sizes, minimizing downtime and avoiding cylinder swaps.
Heavy Assembly Pressing
Leverage the 14074 N push force for heavy-duty joining operations where the final pressing depth requires precise mechanical fine-tuning.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX650-75S the Right Cylinder?
Choose this 160 mm bore when an 80 mm bore (providing 3518 N push at 0.7 MPa) is insufficient, but a 200 mm bore is too large. The 650 mm stroke exceeds standard ranges but remains within the 1500 mm maximum, while the 75 mm adjustment window is ideal for variable end-stops. Because the stroke is 650 mm, an external guide is recommended to manage side loads on the 40 mm rod.
To match this ISO 15552 interchangeable cylinder, specify the 160 mm bore, 650 mm stroke, 75 mm adjustment, PT tapered ports, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR.
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 SAIJ160AX650-75S FAQ
At 0.7 MPa operating pressure, this 160 mm bore cylinder generates 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 rear adjuster screw lets you shorten the effective travel from the 650 mm nominal stroke down to 575 mm. This mechanical stop fine-tunes the end position during commissioning but does not lock the load without continuous air pressure.
