About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-75
The AirTAC SAIJ160X800-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It delivers substantial thrust, offering 14074N push force at 0.7 MPa, making it suited for heavy-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches.
With a nominal 800 mm stroke and a 75 mm adjustment range, this model provides a usable travel window of 725 to 800 mm. You can fine-tune the retract end-position at commissioning without swapping the cylinder or adding external stops. The piston rod uses SUS420J2 stainless steel for corrosion resistance, while the PT tapered port threads ensure a tight, reliable pneumatic connection.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-75 Is Used
Heavy Press Positioning
Dial in the exact 725-800 mm end-stop during heavy press commissioning to accommodate varying material thicknesses without changing the cylinder.
Pallet Size Changeover
Quickly adjust the retract position on a conveyor line to handle different pallet lengths, using the 75 mm trim to adapt the stroke on the fly.
Large Format Ejection
Eject large manufactured parts from a mold or fixture, fine-tuning the ejection reach to clear the machine bed precisely.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-75 the Right Cylinder?
Choose this 160 mm bore when the 100 mm bore's 5497N push at 0.7 MPa is insufficient, but you want to avoid stepping up to the massive 200 mm size. The 75 mm rear adjuster is ideal for product-size changeovers on a line, letting you dial in the exact end-stop without mechanical rebuilds. Remember that the adjuster is a travel stop, not a lock; the SAIJ does not hold loads without live air. For fail-safe load holding, select the SAIL or BSAI series instead.
At 800 mm of travel, the 40 mm diameter rod and M36x2 thread provide a robust interface, but long unsupported strokes demand an external guide to prevent side-loading damage. This cylinder is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets. Operating speed is 30-500 mm/s.

- ✓ 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 SAIJ160AX800-75 FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates 14074N of push force and 9425N of pull force. It can deliver a maximum of 2050 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from 800 mm down to 725 mm. It only sets the travel end and provides deceleration via the air cushion; it does not lock or hold the load without continuous air pressure.
