Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-10
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 450mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-10
The AirTAC SAIJ160X450-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a substantial 10053N pull force at 0.5 MPa, with a usable travel window of 440-450mm created by the 10mm adjustment screw. This built-in stopper allows you to fine-tune the retract end position during commissioning without adding external physical stops.
This unit uses a SUS304 stainless steel rod for superior corrosion resistance and features a PT tapered G3/4 port. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches. The rear adjuster acts purely as a travel stop to set deceleration, meaning it will not hold a load without continuous live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-10 Is Used
Heavy Press Tuning
Dial in the exact 440-450mm end position during heavy press commissioning to accommodate material thickness variations without swapping out the entire actuator.
Product Changeover Stops
Adjust the retract stop on packaging lines to handle different package lengths quickly, using the rear screw rather than repositioning external hard stops.
Large Assembly Fixtures
Provide robust 10053N pull force for large component seating while retaining the flexibility to trim 10mm off the travel for precise fixture alignment.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX450-10 the Right Cylinder?
Choose this 160mm bore when you need heavy thrust that exceeds the 6136N pull force of the 125mm bore, but less than the massive 15708N pull of the 200mm series. An adjustable stroke is ideal for machine setups requiring a precise variable end-stop during product changeovers, unlike a fixed-stroke SAI cylinder. For any application using a 450mm stroke or more, you must use an external guide to prevent excessive side loading on the 40mm rod.
When replacing an ISO 15552 cylinder, match the 160mm bore, 450mm stroke, 10mm adjustment, PT G3/4 port, and standard mounting interface. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options. Because this cylinder lacks an -S magnet, position sensing requires adding external switches. If your process requires load-holding without live air, use an external rod lock or select an AirTAC SAIL or 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 SAIJ160BX450-10 FAQ
At 0.5 MPa operating pressure, this 160mm bore cylinder provides 10053N of push force and 9425N of pull force. It can reach up to 18095N push force at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective travel from 450mm down to 440mm. This creates a 440-450mm adjustable window for fine-tuning the end position at commissioning, but it acts only as a stop and does not lock the load without live air.
