About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-20
The AirTAC SAIJ160X800-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 780-800 mm usable travel window. Delivering 10053 N of push force at 0.5 MPa, this large-bore actuator handles heavy-duty positioning. It uses a SUS420J2 stainless steel rod for superior corrosion resistance and comes with PT tapered port threads.
A defining feature of this specific SKU is the external rear stopper, which fine-tunes the end position at commissioning without requiring physical cylinder swaps. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Note that the rear adjuster acts only as a travel stop, not a lock, so live air pressure is required to maintain the load.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-20 Is Used
Heavy Press Tuning
Dial in the exact 780-800 mm end-stop during machinery setup to perfect heavy pressing operations without swapping actuators.
Product Changeover
Quickly adjust the stroke length on packaging lines when product sizes change, using the rear screw to set new travel limits.
Large Jig Positioning
Fine-tune the extended position of heavy industrial jigs at commissioning, ensuring precise alignment before full production runs.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX800-20 the Right Cylinder?
Choose this 160 mm bore when you need substantial thrust that exceeds the 3927 N push force of a 100 mm bore at 0.5 MPa, but less than the massive 15708 N output of a 200 mm bore. The 20 mm adjustment range is ideal for machinery changeover, allowing you to dial in the exact end-stop without adding external stops. For fixed travel without manual tuning, the standard SAI cylinder is sufficient.
Because this model features an 800 mm stroke, the long unsupported rod (40 mm diameter, M36x2 thread) is susceptible to side-loading; an external guide is recommended to prevent binding. If your process requires holding the load safely without live air pressure, this cylinder will not suffice—you should look at the SAIL or BSAI locking variants instead. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ160AX800-20 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. It can reach up to 18095 N push force at 0.9 MPa.
The rear adjusting screw allows you to shorten the effective stroke by up to 20 mm, providing a usable travel window of 780 to 800 mm. This stopper sets the end position but does not lock the load without live air pressure.
