About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX240-30
The AirTAC SAIJ160X240-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 240 mm stroke that can be dialed back by up to 30 mm, giving operators a precise 210-240 mm usable travel window for fine-tuning end positions during commissioning. Equipped with a SUS304 stainless steel rod, it handles heavy loads with 10053 N of pull force at 0.5 MPa.
This extruded aluminum profile cylinder omits tie-rod construction and integrates sensor grooves on both sides for flexible switch mounting. It operates at speeds of 30-500 mm/s and features PT tapered port threads (G3/4). The rear adjuster acts strictly as a mechanical stop to set the travel end and does not lock or hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX240-30 Is Used
Heavy Machinery Setup
Dial in the exact 210-240 mm end position during heavy machinery commissioning to achieve perfect alignment without machining custom spacers.
Product Changeover
Quickly adjust the stroke on packaging lines to handle different box sizes, using the 30 mm trim range to adapt the stopper point on the fly.
Variable End Stops
Provide a tunable mechanical stop for heavy industrial presses, ensuring precise bottoming out without needing to recalibrate the entire pneumatic system.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX240-30 the Right Cylinder?
Select this 160 mm bore cylinder when an application requires substantial force (10053 N pull at 0.5 MPa) alongside variable end-stop positioning. If your setup needs less thrust, stepping down to a 125 mm bore yields 5734 N of pull force. Choose the SAIJ adjustable design over a fixed SAI cylinder when you need to accommodate product size changeovers without physically swapping the actuator or adding external stops.
For a direct ISO 15552 replacement match, verify the 160 mm bore, 240 mm stroke, 30 mm adjustment range, PT port threads, and the absence of a magnet. Because the 240 mm stroke is relatively short for this large bore, side-load concerns are minimal, but an external guide is still recommended for heavy off-center loads. If true load-holding is required without continuous air pressure, use an external rod lock or pilot-operated check valve, as the rear stopper is not a brake.
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 SAIJ160BX240-30 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of pull force and 14074 N of push force. It can reach a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective travel from the nominal 240 mm down to 210 mm. This creates a 30 mm adjustable window for fine-tuning the retract end position at commissioning, but it functions only as a travel stop and does not lock the load.
