About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX400-40
The AirTAC SAIJ160X400-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 400 mm nominal travel by up to 40 mm for a precise 360-400 mm usable window. It delivers substantial thrust, generating 10053 N of push force and 9425 N of pull force at 0.5 MPa. This bore size features a robust 40 mm piston rod, a G3/4 port, and 50 mm of variable air cushioning at both ends to manage heavy kinetic energy.
This specific configuration incorporates a SUS304 stainless steel rod (material code B) for superior corrosion resistance and includes PT tapered port threads. Because the stroke reaches 400 mm, the 40 mm rod diameter provides excellent rigidity, though an external guide is still recommended to handle potential side loads over this extended travel distance.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX400-40 Is Used
Heavy Press Tuning
Dial in the exact 360-400 mm end position during machine setup to accommodate varying material thicknesses in large-scale forming presses.
Product Changeover Stops
Adjust the retract stop on the fly for different pallet sizes on a heavy-duty conveyor line without swapping out the entire cylinder.
Large Assembly Fixtures
Securely position heavy automotive components using the 10053 N push force while fine-tuning the clamping distance during commissioning.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX400-40 the Right Cylinder?
Selecting this 160 mm bore makes sense when an application requires heavy thrust—such as the 10053 N push force at 0.5 MPa—stepping up from a 125 mm bore that provides 6136 N. The adjustable-stroke feature is chosen over a fixed SAI cylinder when you need to fine-tune the retract end position during commissioning or product changeover without adding external stops. If your machine requires load holding without live air pressure, note that the rear adjuster on this SAIJ acts only as a travel stop; you should instead utilize an SAIL air-released lock, a BSAI clamp-lock, or an external rod lock.
To match this exact ISO 15552 interchangeable replacement, verify the 160 mm bore, 400 mm nominal stroke, 40 mm adjustment range, PT port threads, and the absence of a magnet (-S). The mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 hardware, deliberately omitting FB, CA, CB, and CR brackets.
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 SAIJ160BX400-40 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At the maximum 1.0 MPa pressure, it achieves up to 2050 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 40 mm, creating a usable travel window of 360-400 mm. This stopper fine-tunes the end position but does not lock the load without live air pressure.
