About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-40
The AirTAC SAIJ160X450-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering heavy-duty thrust for demanding automation. It features a robust 40mm SUS304 stainless steel rod and a PT tapered G3/4 port. With a nominal 450mm stroke and a 40mm adjustment range, you can dial back the effective travel to anywhere in a 410-450mm window without swapping hardware.
This bore size generates 14074N of push force at 0.7MPa and safely operates at speeds of 30-500mm/s. The extruded aluminum barrel includes sensor grooves on both sides, though this specific configuration omits the magnet. For load-holding without live air pressure, note that the rear adjuster acts purely as a travel stop and not a brake; you would need an external rod lock or a SAIL cylinder for those tasks.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-40 Is Used
Heavy Press Tuning
Dial in the exact 410-450mm end position during heavy press commissioning to accommodate material thickness variations without changing the cylinder.
Product Changeover
Quickly adjust the stroke window on a conveyor diverting station when switching to different pallet sizes, saving setup time on the line.
Variable End Stops
Use the rear stopper screw to set precise retract positions for large automated assembly machines, avoiding the need for external mechanical stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-40 the Right Cylinder?
Select this 160mm bore model when an application requires substantial force, stepping up from a 125mm bore that provides 8590N push at 0.5MPa. The adjustable-stroke design is ideal for machine setups requiring fine end-position tuning during commissioning or product changeovers, preventing the need to bolt on external stops. It mounts via Basic, FA, LB, TC, FTC, TCM1, or TCM2 interfaces, omitting FB and CA options. To match this cylinder for an ISO 15552 replacement, verify the 450mm stroke, 40mm adjustment, PT port, and SUS304 rod.
Because the 450mm stroke is substantial, the heavy piston and rod assembly can generate significant side loads if the load is unsupported. Always guide the external load to prevent rod binding, as even the thick 40mm rod cannot compensate for severe misalignment over long extensions.
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 SAIJ160BX450-40 FAQ
At 0.9 MPa operating pressure, this 160mm bore cylinder generates 18095N of push force and 9425N of pull force at 0.5 MPa. The maximum thrust at 1.0 MPa is 2050 kgf.
The rear adjuster screw lets you shorten the nominal 450mm stroke by up to 40mm, providing an effective travel window of 410-450mm. This stopper only sets the end position and does not lock the load without live air.
