About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-50S
The AirTAC SAIJ160X700-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty automation. With a nominal 700 mm stroke and a 50 mm adjustment range, it provides a usable travel window of 650 to 700 mm. This allows precise end-position tuning during commissioning without swapping out the entire cylinder. At 0.9 MPa, it generates 18095 N of push force and 14074 N at 0.7 MPa.
This SKU features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-50S Is Used
Heavy Press Positioning
Fine-tune the 650-700 mm retraction point on large presses during setup, accommodating different die heights without machining new hard stops.
Pallet Changeover
Adjust the stroke end on the fly for varying pallet sizes on a 160 mm actuator moving heavy loads at up to 500 mm/s.
Long-Stroke Assembly
Dial in the exact 700 mm travel limit for large component seating, using the rear stopper to prevent overtravel on heavy assemblies.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-50S the Right Cylinder?
Choose this 160 mm bore when an 80 mm cylinder (providing 4523 N push at 0.9 MPa) lacks the force for heavy moving masses, but a 200 mm bore is physically oversized. The adjustable 650-700 mm window is ideal for product changeovers on long-stroke lines, removing the need to bolt on external stops. For load-holding without continuous air pressure, this cylinder is insufficient; the rear stop is not a lock, so you must specify an AirTAC SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 700 mm stroke, 50 mm adjustment, PT tapered port thread, and the -S magnet requirement. Because the stroke is 700 mm, the 40 mm diameter rod and M36x2 thread provide rigidity, but long unsupported travel demands an external guide to prevent side-loading damage. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ160AX700-50S FAQ
This 160 mm bore cylinder generates 10053 N of push force at 0.5 MPa, 14074 N at 0.7 MPa, and 18095 N at 0.9 MPa. The pull force at 0.5 MPa is 9425 N.
The rear adjuster screw allows you to trim the effective stroke by up to 50 mm, creating a 650 to 700 mm usable travel window. It acts as a mechanical stop to fine-tune the end position and does not lock the load without air pressure.
