About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX240-50
The AirTAC SAIJ160X240-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits up to 50 mm of end-position trimming. This creates a usable travel window from 190 to 240 mm, allowing you to dial in the exact retract distance during commissioning without swapping hardware. It delivers a robust 10053 N pull force at 0.5 MPa, making it ideal for heavy-duty positioning.
This specific SKU is configured with a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, ready to accept CMSE reed or DMSE electronic solid-state switches if a magnet is added later. The rear stopper acts purely as a travel limit and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX240-50 Is Used
Product Changeovers
Leverage the 190-240 mm adjustable travel window to rapidly switch between different package sizes on a packaging line without changing the cylinder.
Heavy-Duty Positioning
Utilize the 10053 N pull force to move heavy pallets or fixtures into exact alignment, fine-tuning the end stop during machine setup.
Welding & Forming
Deploy the SUS304 stainless rod in manufacturing cells where weld spatter or moisture is present, ensuring reliable actuation over a 30-500 mm/s speed range.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX240-50 the Right Cylinder?
Select this 160 mm bore actuator when an application requires substantial thrust—such as the 14074 N push force at 0.7 MPa—combined with a variable end-stop. The 50 mm adjustment range is perfect for accommodating multiple product sizes on a single line without bolting on external stops. If you need less force, stepping down to a 100 mm bore yields 3681 N of pull force at 0.5 MPa.
Because the nominal stroke of 240 mm is below the 300 mm threshold, a supplementary external guide is less critical, though the robust 40 mm rod and M36x2 thread handle high side loads well. For any load-holding requirements without continuous air pressure, note that this cylinder's adjuster is a stop, not a lock; you would need to explore a SAIL or BSAI series cylinder instead. This unit is dimensionally interchangeable with ISO 15552 cylinders and uses the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAIJ160BX240-50 FAQ
At 0.5 MPa, this 160 mm bore cylinder provides 10053 N of pull force and 14074 N of push force. At the maximum operating pressure of 1.0 MPa, it can deliver up to 2050 kgf.
The rear adjuster screw lets you shorten the effective stroke by up to 50 mm from the 240 mm nominal length, creating a 190-240 mm travel window. It functions as a mechanical stop for end-position tuning and does not lock the load without live air pressure.
