About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-40S
The AirTAC SAIJ160X800-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 760 to 800 mm. Belonging to the 160 mm bore class, it delivers substantial thrust, generating 14074 N of push force at 0.7 MPa. The extruded aluminum barrel features sensor grooves on both sides, and this specific configuration includes a SUS304 stainless steel rod and a magnet for position detection.
Instead of relying on fixed stops, the rear adjusting screw allows you to fine-tune the end position at commissioning without swapping the cylinder. This model uses PT tapered ports and operates at speeds between 30 and 500 mm/s. The adjuster acts purely as a travel stop to set the deceleration point alongside the variable air cushions, meaning it cannot hold a load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-40S Is Used
Heavy Press Tuning
Dial in the exact 760 to 800 mm end position during machine commissioning to accommodate material thickness variations without adding external stopper blocks.
Large Product Changeover
Quickly adjust the rear stopper screw on a production line when switching between large pallet sizes, saving downtime compared to physically swapping cylinders.
Long-Stroke Forming
Leverage the 14074 N push force at 0.7 MPa for deep drawing or forming operations, using the adjuster to precisely limit the travel window and prevent over-travel.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX800-40S the Right Cylinder?
Select this 160 mm bore cylinder when an application requires high force combined with variable end-stop positioning, such as pressing or heavy product changeovers. If the 14074 N push force at 0.7 MPa exceeds your requirements, stepping down to a 125 mm bore yields 8590 N, whereas moving up to a 200 mm bore provides 21991 N. For fixed-position tasks without the need for commissioning adjustments, a standard SAI cylinder is sufficient.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 800 mm stroke, 40 mm adjustment range, PT port threads, and the -S magnet. Because this cylinder features an 800 mm stroke, the 40 mm rod diameter and M36x2 thread will carry significant side loads; an external guide is recommended to prevent rod binding over this long unsupported travel. For load-holding without continuous air pressure, integrate an external rod lock or consider the SAIL or BSAI series.

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 SAIJ160BX800-40S FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 40 mm, creating a usable travel window of 760 to 800 mm. It functions as a mechanical stop to fine-tune the end position and works in conjunction with the variable air cushions to decelerate the piston.
At an operating pressure of 0.7 MPa, the SAIJ160X800-40-S generates a push force of 14074 N and a pull force of 9425 N. The maximum push force reaches 18095 N at 0.9 MPa.
