About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-40
The AirTAC SAIJ160X700-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 660 to 700 mm, allowing you to trim the effective stroke by up to 40 mm during commissioning without swapping the cylinder. Built with an extruded aluminum barrel, it delivers robust thrust, pushing 14074 N at 0.7 MPa.
This model features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and uses PT tapered port threads with a G3/4 connection. The rear screw acts purely as a mechanical stop to fine-tune the end position; it does not lock or hold the load without continuous live air pressure.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-40 Is Used
Product Changeovers
Dial in the 660-700 mm travel window during format size changes on an automated line, avoiding the need to physically swap out long-stroke cylinders.
Heavy Press Positioning
Leverage the 14074 N push force at 0.7 MPa to move heavy assemblies, using the rear stopper to precisely set the final retracted end position.
Commissioning Fine-Tuning
Trim up to 40 mm of stroke during machine setup to perfect tooling alignment, compensating for mechanical tolerance stack-up without adding external stops.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX700-40 the Right Cylinder?
Select this 160 mm bore when an 80 mm bore (providing 3518 N push at 0.7 MPa) is insufficient, but a 200 mm bore is excessive. The adjustable 660-700 mm travel window is ideal for product changeovers on a line, eliminating the need to bolt on external stops or buy a fixed-stroke SAI cylinder. Because the 700 mm stroke is substantial, an external guide is recommended to handle side loads and prevent rod bending.
For a direct ISO 15552 replacement match, ensure you specify the 160 mm bore, 700 mm nominal stroke, 40 mm adjustment range, PT G3/4 port, and the SUS420J2 rod material. Note that SAIJ supports a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. If your application requires the load to be held without air pressure, use an external rod lock or look to the SAIL or BSAI series 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 SAIJ160AX700-40 FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder generates a push force of 14074 N and a pull force of 9425 N. It can reach a maximum push force of 18095 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the 700 mm nominal stroke by up to 40 mm, creating a usable travel window of 660 to 700 mm. The adjuster functions as a mechanical stop to set the end position and does not lock the load without live air pressure.
