About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X160-20
The AirTAC SAIJ160X160-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 140 to 160 mm, letting you dial back the end position by up to 20 mm during commissioning without bolting on external stops. Built for heavy-duty tasks, its 160 mm bore yields 10053 N of pull force at 0.5 MPa.
This model uses a robust 40 mm carbon steel rod with an M36x2 thread, paired with 50 mm variable air cushions at both ends to manage high kinetic energy. The extruded aluminum barrel includes sensor grooves on both sides for mounting standard switches, while the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X160-20 Is Used
Heavy Pressing Tuning
Fine-tune the 140-160 mm travel window during heavy pressing operations to accommodate material thickness variations without changing the cylinder.
Product Line Changeover
Quickly adjust the retract end-stop by up to 20 mm when switching a production line to a new product size, saving setup time.
Large Jig Alignment
Precisely position large jigs and fixtures using the 10053 N pull force, relying on the M36x2 thread rod for secure mounting.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X160-20 the Right Cylinder?
Choose this 160 mm bore when your application requires substantial thrust, such as 14074 N push at 0.7 MPa, but a neighbouring 125 mm bore provides 5734 N pull at 0.5 MPa if you need a lighter footprint. The adjustable stroke is ideal for machine setups requiring variable end-stops or product-size changeovers, avoiding the need to physically swap out a fixed-stroke SAI cylinder. For true load-holding without continuous air pressure, you would need to step up to an AirTAC SAIL or BSAI series, as the SAIJ adjuster is not a lock.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 160 mm nominal stroke, 20 mm adjustment range, PT G3/4 port thread, and standard carbon steel rod. Because the stroke is 160 mm, side-load risks are moderate, but for any stroke of 300 mm or more, an external guide is mandatory to prevent rod binding. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

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 SAIJ160X160-20 FAQ
At 0.5 MPa, the SAIJ160X160-20 provides 10053 N of push force and 9425 N of pull force. At 0.9 MPa, the push force increases to 18095 N.
The rear adjuster screw allows you to shorten the effective stroke from 160 mm down to 140 mm. This creates a 20 mm adjustable travel window for fine-tuning the end position at commissioning, but it acts as a stop and does not lock the load without live air.
