About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-75
The AirTAC SAIJ160X800-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 800 mm stroke that can be dialed back by up to 75 mm, giving operators a 725-800 mm usable travel window for precise end-position tuning during commissioning. Belonging to the 160 mm bore class, it delivers a robust 14074 N of push force at 0.5 MPa and 18095 N at 0.9 MPa, making it suitable for heavy-duty positioning tasks.
This variant is equipped with a SUS304 stainless steel rod (option B) for superior corrosion resistance and features a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the internal magnet, meaning electronic DMSE or reed CMSE switches cannot be mounted without a configuration change. The rear adjuster acts purely as a mechanical stop to fine-tune the travel end without needing external stops, while the shared variable air cushions manage deceleration.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-75 Is Used
Heavy Press Setup
Dial in the exact 725-800 mm end-stop for large metalworking presses during initial commissioning without adding external mechanical stops.
Product Changeover
Quickly adjust the retract position to accommodate varying pallet sizes on a heavy-duty conveyor line, reducing machine downtime.
Variable End-Stop Tooling
Fine-tune the stroke on automated heavy-material handling jigs where the final clamping position requires on-the-fly mechanical adjustment.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-75 the Right Cylinder?
When sizing this actuator, consider the neighboring 200 mm bore if your application requires significantly higher thrust, as it provides 21991 N of push force at 0.5 MPa compared to this 160 mm bore's 14074 N. Conversely, stepping down to a 125 mm bore reduces the force output to 8590 N at 0.5 MPa. The adjustable stroke is highly beneficial for machine setups requiring variable end-stops or product-size changeovers, allowing you to trim the travel back without physically swapping the cylinder.
Because the nominal stroke is 800 mm, an external guide is strongly recommended to prevent excessive side-loading on the extended rod, despite the robust M36x2 rod thread. To replace this ISO 15552 cylinder, match the 160 mm bore, 800 mm stroke, 75 mm adjustment, PT G3/4 port, and SUS304 rod material. Note that the rear adjuster is a travel stop, not a lock; if the machine loses air pressure, the load will not hold. For fail-safe load holding, utilize an external pilot-operated check valve or explore the SAIL or BSAI series.
The mounting interface utilizes the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR brackets found on other variants.
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 SAIJ160BX800-75 FAQ
The rear adjuster is an external stopper that lets you mechanically shorten the effective travel by up to 75 mm. This creates a 725-800 mm usable stroke window, allowing you to fine-tune the end position at commissioning without swapping the cylinder.
At an operating pressure of 0.5 MPa, it provides 14074 N of push force and 9425 N of pull force. At 0.9 MPa, the push force increases to 18095 N.
