About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-20S
The AirTAC SAIJ160X950-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering robust thrust for heavy-duty automation. It yields 10053N of push force and 9425N of pull force at 0.5 MPa, scaling up to 18095N at 0.9 MPa. The integrated -20 adjustment code allows you to dial back the nominal 950mm stroke, providing a precise 930-950mm usable travel window during commissioning.
This specific SKU features a SUS304 stainless steel rod (code B) for superior corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors housed in the dual-side barrel grooves. Fluid is filtered air operating at 0.15-1.0 MPa, with variable air cushions at both ends. The rear stopper acts purely as a travel end-point tuner and does not lock the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-20S Is Used
Heavy Machinery Changeover
Fine-tune the 930-950mm retract end-stop during heavy equipment format changes without physically replacing the actuator or bolting on external mechanical stops.
Large Press Positioning
Leverage the 18095N push force at 0.9 MPa to actuate large presses, using the rear adjuster to precisely set the deceleration point and avoid impact shock.
Pallet Handling Stops
Adjust the end position on the fly for varying pallet sizes on a conveyor line, relying on the SUS304 rod to withstand harsh industrial environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX950-20S the Right Cylinder?
Select this 160mm bore actuator when an application requires substantial force that exceeds the 6136N push capacity of a 125mm cylinder, but falls short of needing the 15708N output of a 200mm unit. The adjustable 930-950mm travel window is ideal for product changeovers on a line, allowing operators to fine-tune the retract position without swapping the cylinder or adding external stops. For holding loads without continuous air pressure, pair this cylinder with an external rod lock or pilot-operated check valve, or specify an AirTAC SAIL or BSAI model.
When replacing an ISO 15552 cylinder, verify the 160mm bore, 950mm stroke, -20 adjustment range, PT tapered port threads, and the -S magnet requirement. Because the 950mm stroke is substantial, the 40mm diameter rod and M36x2 thread provide rigidity, but an external guide is strongly recommended to prevent excessive side-loading on the unsupported piston rod. This model uses the SAIJ mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ160BX950-20S FAQ
At 0.5 MPa operating pressure, this 160mm bore cylinder provides 10053N of push force and 9425N of pull force. At 0.9 MPa, the push force increases to 18095N.
The rear adjusting screw allows you to shorten the effective stroke by up to 20mm. This creates a usable travel window of 930-950mm from the nominal 950mm stroke, enabling precise end-position tuning at commissioning. The adjuster is a stop, not a lock, and requires live air to hold the load.
