About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX240-50S
The AirTAC SAIJ160X240-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the effective travel by up to 50 mm, creating a precise 190-240 mm usable window for commissioning. It delivers a robust 10053 N pull force at 0.5 MPa and 14074 N at 0.7 MPa, making it suitable for heavy-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This specific SKU is configured with a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port. It is equipped with a magnet for position detection, compatible with AirTAC CMSE reed and DMSE electronic solid-state sensors. The rear stopper screw acts solely as a travel end-stop for fine-tuning without swapping the cylinder, not as a locking device.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX240-50S Is Used
Heavy-Duty Pressing
Dial in the exact 190-240 mm end-position for heavy pressing or forming tasks, ensuring precise contact depth during machine setup.
Product Changeover
Quickly adjust the retract stop for different package sizes or pallet heights on a packaging line without changing the cylinder.
Variable End-Stop Positioning
Set custom retract distances for automated assembly equipment, fine-tuning the travel window to accommodate multiple part lengths.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX240-50S the Right Cylinder?
Choose this 160 mm bore when a 100 mm bore (3927 N push at 0.5 MPa) lacks the necessary thrust, but step down if the 80 mm bore (2513 N push) is sufficient for your payload. An adjustable stroke is ideal for product changeovers or variable end-stops, allowing you to dial in the exact 190-240 mm position without adding external stops, unlike a fixed-stroke SAI cylinder. For an exact ISO 15552 replacement, match the 160 mm bore, 240 mm stroke, 50 mm adjustment, PT port, SUS304 rod, and -S magnet.
Because the stroke is 240 mm, ensure proper guiding to prevent side-loading on the rod. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. If your application requires holding the load without live air pressure, the rear adjuster cannot perform this function; select an external rod lock or a SAIL/BSAI cylinder instead.
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 SAIJ160BX240-50S FAQ
At 0.5 MPa, it provides 10053 N pull force and 14074 N at 0.7 MPa. The maximum push force is 18095 N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the nominal 240 mm stroke by up to 50 mm, resulting in a 190-240 mm usable travel window. It only sets the end position and does not lock the load.
