About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX600-20S
The AirTAC SAIJ160X600-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end-of-travel position during commissioning. With a 600 mm nominal stroke and a 20 mm adjustment range, it provides a usable travel window of 580 to 600 mm without requiring external stops. It delivers substantial thrust, pushing with 14074 N and pulling with 9425 N at 0.7 MPa operating pressure.
This specific configuration includes a SUS304 stainless steel piston rod (option B) for superior corrosion resistance and features a built-in magnet for use with CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the unit operates at speeds between 30 and 500 mm/s. It utilizes PT tapered ports and offers adjustable pneumatic cushions at both ends to manage impact energy.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX600-20S Is Used
Heavy Press Tuning
Dial in the exact 580-600 mm end position during machine commissioning to accommodate material thickness variations without adding bulky external stopper blocks.
Product Changeover
Quickly adjust the retract end-stop on a packaging line when switching to a different pallet or product size, using the rear screw to fine-tune the travel window.
Corrosive Forming
Leverage the SUS304 stainless steel rod option to push heavy loads in humid or washdown environments while relying on the built-in cushion to absorb kinetic energy.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX600-20S the Right Cylinder?
Choose this 160 mm bore when an application requires heavy thrust—such as the 14074 N push force at 0.7 MPa—exceeding the 5497 N push capacity of the 100 mm bore. The adjustable 580-600 mm travel window is ideal for machinery that undergoes frequent product changeovers, allowing operators to dial in the exact end position without swapping the cylinder. Because the stroke is 600 mm, the long unsupported piston rod requires an external guide to prevent excessive side-loading and premature seal wear.
Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for fail-safe load holding, consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder. To match this ISO 15552 interchangeable cylinder exactly, specify the 160 mm bore, 600 mm stroke, 20 mm adjustment, PT port thread, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and the -S magnet option.
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 SAIJ160BX600-20S FAQ
At a 0.7 MPa operating pressure, this 160 mm bore cylinder generates a push force of 14074 N and a pull force of 9425 N. At the maximum 1.0 MPa pressure, it can achieve a push force of up to 10053 N.
The rear adjuster screw lets you shorten the effective travel from the nominal 600 mm down to 580 mm. This creates a 580-600 mm adjustable window, allowing precise end-position tuning at commissioning without replacing the cylinder.
