About the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX80-30S
The AirTAC SAIJ160X80-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 50-80 mm usable travel window from its 80 mm nominal stroke. Delivering 9425 N of pull force at 0.5 MPa, it handles heavy positioning tasks. The barrel is extruded aluminum with sensor grooves on both sides, and this variant includes a magnet for position feedback.
This model uses a SUS420J2 stainless steel rod for improved corrosion resistance and PT tapered ports for sealing. The rear adjuster acts purely as a travel stop to fine-tune the end position during commissioning; it does not hold the load without live air pressure. For dead-load holding, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX80-30S Is Used
Heavy Press Tuning
Dial in the exact 50-80 mm travel window during machine setup to accommodate varying material thicknesses without adding external stopper blocks.
Assembly Line Changeover
Adjust the retract end position on the fly during product size transitions, saving downtime compared to replacing fixed-stroke actuators.
Robust End-Stop Positioning
Leverage the 40 mm SUS420J2 stainless rod and M36x2 thread to handle high side-loading forces while setting precise heavy-load endpoints.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160AX80-30S the Right Cylinder?
Choose this 160 mm bore when the 100 mm bore (3681 N pull at 0.5 MPa) is insufficient but you need less thrust than the 200 mm bore. The adjustable 30 mm trim is ideal for product changeovers where exact end-of-stroke positioning varies without swapping cylinders. When matching ISO 15552 dimensions, verify the 80 mm stroke, 30 mm adjustment, PT port type, and the -S magnet.
Although the 80 mm stroke is short, the 40 mm rod and M36x2 thread provide excellent rigidity against side loads. Because the rear adjuster and air cushions only decelerate the moving mass, never use them as a mechanical lock for suspended loads.
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 SAIJ160AX80-30S FAQ
At 0.5 MPa, this 160 mm bore cylinder generates 9425 N of pull force and 10053 N of push force. It reaches a maximum of 2050 kgf at 1.0 MPa.
The rear adjuster allows you to shorten the 80 mm nominal stroke by up to 30 mm, creating a 50-80 mm travel window. The adjuster is a mechanical stop for end-position tuning and does not lock the load without air pressure.
