About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX60-20S
The AirTAC SAIJ160X60-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty operations. With a 60 mm nominal stroke and a 20 mm adjustment range, it provides a usable travel window of 40-60 mm. This allows precise end-position tuning at commissioning without swapping the cylinder. At 0.7 MPa, it generates 14074 N of push force.
This variant features an SUS420J2 stainless steel rod (code A) for improved corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel integrates sensor grooves on both sides. Fluid must be filtered air (40 um), operating within a 30-500 mm/s speed range and a -20 to +70 C temperature environment.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX60-20S Is Used
Heavy Press Fit Tuning
Dial in the exact 40-60 mm insertion depth for heavy press fits during machine setup, preventing over-travel without adding external stops.
Product Size Changeover
Quickly adjust the rear stopper on a production line when shifting between product variants, saving time on mechanical reconfiguration.
High-Force End Positioning
Leverage the 14074 N push force at 0.7 MPa to move heavy payloads, relying on the rear screw to finely tune the final resting position.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX60-20S the Right Cylinder?
Select this 160 mm bore when an 80 mm bore (3518 N push at 0.5 MPa) is insufficient but a 200 mm bore is oversized. The adjustable stroke is ideal for applications requiring variable end stops or product-size changeovers, functioning as a travel stop rather than a load-holding lock. For position holding without live air, consider an AirTAC SAIL or BSAI cylinder. To match this ISO 15552 replacement, specify: 160 mm bore, 60 mm stroke, 20 mm adjustment, PT tapered port, SUS420J2 rod, and a magnet (-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 SAIJ160AX60-20S FAQ
At an operating pressure of 0.7 MPa, this 160 mm bore cylinder produces 14074 N of push force and 13074 N of pull force. At 0.5 MPa, the push force is 10053 N.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 60 mm nominal stroke by up to 20 mm. This creates a usable travel window of 40-60 mm for fine-tuning the end position without replacing the cylinder.
