Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-75
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-75 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 750mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-75
The AirTAC SAIJ160X750-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel window between 675 and 750 mm without swapping components. Built with a 160 mm bore, it delivers substantial thrust, generating 18095 N of push force at 0.9 MPa. This makes it well-suited for heavy-duty positioning tasks where precise end-stop calibration is essential.
This model incorporates a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and features PT tapered port threads (G3/4) for secure pneumatic connections. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic sensors, though no magnet is installed on this specific unit. The rear adjustment screw acts purely as a travel stop to set the retract position, meaning it does not lock the load mechanically without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-75 Is Used
Heavy Press Tuning
Dial in the exact 675-750 mm retract position during heavy press setup, compensating for tooling wear without machining new hard stops.
Product Changeover
Adjust the travel end-stop on the fly when switching to different pallet sizes on a high-thrust conveyor line.
Fixture Calibration
Fine-tune the clamping distance of large fixtures during machine commissioning to ensure precise 0.9 MPa contact forces.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX750-75 the Right Cylinder?
Choose this 160 mm bore cylinder when an application requires heavy force output combined with on-the-fly stroke tuning; if you need less force, stepping down to a 125 mm bore yields 11045 N at 0.9 MPa. The 75 mm adjustment range is particularly useful for product changeovers on automated lines, allowing operators to dial in the exact end position without adding external physical stops. For fixed-position applications that never require travel trimming, a standard SAI cylinder offers the same ISO 15552 footprint and thrust capabilities.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 750 mm stroke, PT G3/4 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2; note that FB, CA, CB, and CR are omitted). Because the 750 mm stroke is long and unsupported, the 40 mm rod diameter cannot fully prevent deflection, so an external guide rail is required to handle side loads. If the machine requires true load holding without continuous air pressure, use an external rod lock or pilot-operated check valve, or switch to an AirTAC SAIL or BSAI clamping cylinder.

- ✓ 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 SAIJ160AX750-75 FAQ
At 0.9 MPa operating pressure, this 160 mm bore cylinder generates 18095 N of push force and 9425 N of pull force at 0.5 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from 750 mm down to 675 mm. It only sets the travel end and does not hold the load without live air pressure.
