About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX60-20
The AirTAC SAIJ80X60-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 40-60 mm usable travel window from its 60 mm nominal stroke. Delivering 2268 N of pull force at 0.5 MPa, it is built with a 25 mm carbon steel rod and a SUS420J2 stainless steel variant. The extruded aluminum barrel includes sensor grooves on three sides.
This model uses PT tapered port threads (G3/8) and offers variable air cushions at both ends to decelerate the load. The rear adjuster acts purely as a mechanical stop for end-position tuning during commissioning; it does not lock or hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX60-20 Is Used
Machine Changeover
Dial in the 40-60 mm travel window during product size transitions to set exact end positions without external stops.
End-Position Tuning
Fine-tune the retract stroke by up to 20 mm at commissioning to compensate for mechanical wear or sensor offsets.
Assembly Pressing
Leverage the 2268 N pull force at 0.5 MPa for moderate-duty pressing operations where exact travel limits must be adjusted on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX60-20 the Right Cylinder?
Choose this 80 mm bore when an application requires higher thrust than a 63 mm bore (1402 N pull at 0.5 MPa) but less than a 100 mm bore (3681 N pull). The 20 mm adjustment range is ideal for dialing in exact end positions during machine setup or product changeover without swapping cylinders or adding external stops. Because the stroke is under 300 mm, side-load risks are minimal, though the 25 mm rod thread handles moderate bending stress well.
For ISO 15552 replacement matching, verify the 60 mm stroke, 20 mm adjustment, PT G3/8 ports, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). This specific configuration lacks a magnet, so it cannot host CMSE reed or DMSE electronic sensors without a -S suffix. If true load-holding is required without live air, consider the SAIL or BSAI 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 SAIJ80 Adjustable Cylinder SAIJ80AX60-20 FAQ
It features a rear adjusting screw that allows you to shorten the 60 mm nominal stroke by up to 20 mm, providing a usable travel window of 40 to 60 mm. This stopper sets the end position but does not hold the load without live air.
At 0.5 MPa operating pressure, it provides 2513 N of push force and 2268 N of pull force. The maximum thrust is 513 kgf at 1.0 MPa.
