Airtac SAIJ160 Adjustable Cylinder SAIJ160BX550-10S
The AirTAC Airtac SAIJ160 Adjustable Cylinder SAIJ160BX550-10S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø160mm bore and 550mm 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 SAIJ160BX550-10S
The AirTAC SAIJ160X550-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 540 to 550 mm. Featuring a 160 mm bore, it generates 10053 N of push thrust at 0.5 MPa and reaches a maximum of 2050 kgf at 1.0 MPa. The extruded aluminum barrel includes sensor grooves on both sides, and this -S variant includes a magnet for direct mounting of CMSE reed or DMSE electronic solid-state switches.
This unit uses a SUS304 stainless steel rod (code B) for superior corrosion resistance and features PT tapered port threads. The rear adjustment screw acts purely as a mechanical stop to fine-tune the retract end position during commissioning without adding external stops. It is not a locking device and will not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX550-10S Is Used
Heavy Press Fine-Tuning
Dial in the exact 540-550 mm end-stop during heavy press commissioning to accommodate material thickness variations without changing hardware.
Automated Line Changeover
Quickly adjust the retract position by up to 10 mm when switching product sizes on a high-force assembly line.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for reliable high-thrust clamping in washdown or chemically exposed manufacturing areas.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX550-10S the Right Cylinder?
Choose this 160 mm bore cylinder when an application requires substantial force (10053 N push at 0.5 MPa) but demands less travel than the 200 mm option, which outputs 15708 N at the same pressure. The 10 mm adjustable stroke is ideal for precision machine setup and product changeovers, allowing you to dial in the exact end-stop without swapping the cylinder. For fixed-stroke requirements without the adjuster, the standard SAI series is the direct alternative.
When replacing an ISO 15552 cylinder, match the 160 mm bore, 550 mm stroke, PT G3/4 port, and the selected mounting set (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Because the 550 mm stroke is relatively long, an external guide is strongly recommended to prevent excessive side-loading on the 40 mm rod and M36x2 thread. Operating speed is 30-500 mm/s.
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 SAIJ160BX550-10S FAQ
The rear adjuster screw lets you shorten the nominal 550 mm stroke by up to 10 mm, creating a 540-550 mm travel window. It functions as a mechanical stop for end-position tuning and relies on the air cushion for deceleration, but it does not lock or hold the load without continuous air pressure.
At a 0.5 MPa operating pressure, it provides 10053 N of push force and 9425 N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 2050 kgf.
