About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX700-30
The AirTAC SAIJ160X700-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 670 to 700 mm. It delivers substantial thrust, generating 10053 N of push force and 9425 N of pull force at 0.5 MPa. This bore size operates with a G3/4 port and a robust 40 mm piston rod.
This specific SKU features a SUS304 stainless steel rod for enhanced corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing direct mounting of CMSE reed or DMSE electronic sensors if a magnet is added later. The rear stopper allows precise end-position tuning at commissioning without adding external stops.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX700-30 Is Used
Heavy Press Tuning
Dial in the exact 670-700 mm retract position during heavy press setup to accommodate different material thicknesses without changing the cylinder.
Variable End Stops
Use the 30 mm rear adjustment screw to fine-tune the machine end-stop during commissioning, avoiding the need to bolt on external mechanical stops.
Product Changeover
Quickly adjust the stroke window on a packaging conveyor to handle varying box sizes on the fly, relying on the heavy 10053 N thrust for actuation.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX700-30 the Right Cylinder?
Choose this 160 mm bore when an application requires heavy thrust beyond the 6136 N push force of the neighboring 125 mm bore, but does not need the extreme 15708 N output of the 200 mm size. The adjustable 670-700 mm travel window is ideal for product changeovers or fine-tuning the retract end-position during machine setup, avoiding the need to physically swap out a fixed-stroke SAI cylinder.
When configuring an ISO 15552 replacement, match the 160 mm bore, 700 mm stroke, 30 mm adjustment, G3/4 port, and required mounting accessories. The SAIJ series supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR options. Because the stroke is 700 mm, an external guide is recommended to prevent side-loading damage to the rod and seals. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for true load-holding, consider an external rod lock or the SAIL series.
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 SAIJ160BX700-30 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 18095 N of push force.
The rear adjuster acts as an external stopper that lets you shorten the effective travel from the nominal 700 mm down to 670 mm. This creates a 30 mm adjustable window for fine-tuning the end position at commissioning, but it is a stop, not a lock, and cannot hold the load without live air.
