About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX220-20S
The AirTAC SAIJ160X220-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 200 to 220 mm. Delivering 10053 N of pull force at 0.5 MPa, this bore size handles heavy industrial loads while utilizing a SUS304 stainless steel rod for superior corrosion resistance.
It features a PT tapered port and an integrated magnet for CMSE and DMSE sensors. The rear stopper screw allows precise end-position tuning during commissioning without adding external stops, though it acts only as a travel limit and does not hold the load without live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX220-20S Is Used
Heavy Press Tuning
Dial in the exact 200-220 mm end position for heavy pressing tasks during initial machine setup without swapping cylinders.
Product Size Changeover
Quickly adapt a production line for varying product lengths by trimming the stroke up to 20 mm at the rear stopper.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod for heavy assembly operations in washdown or corrosive manufacturing environments.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX220-20S the Right Cylinder?
Select this 160 mm bore when a 100 mm bore yields insufficient force (628 N push at 0.5 MPa) but a 200 mm bore is oversized. The adjustable 200-220 mm window is perfect for product-size changeovers, offering more flexibility than a fixed SAI cylinder. For position holding without live air, use a SAIL or BSAI lock cylinder, as this adjuster is strictly a stop.
Since the 220 mm stroke exceeds 300 mm only marginally, external guidance is still recommended to manage side loads. Ensure your ISO 15552 replacement matches the PT port, SUS304 rod, and -S magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and 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 SAIJ160BX220-20S FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of pull force and 14074 N of push force at 0.7 MPa.
The rear adjuster screw allows you to shorten the 220 mm nominal stroke by up to 20 mm, creating a 200-220 mm travel window. It functions as a hard stop for position tuning and does not lock the load.
