About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-20
The AirTAC SAIJ80X600-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits up to 20 mm of end-position tuning. This yields a usable travel window of 580-600 mm, allowing precise retraction stops without adding external physical stops. It delivers a robust 4523 N push force at 0.9 MPa, making it suitable for heavy actuation.
This specific SKU is configured with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic sensors, though this unit is supplied without a piston magnet.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-20 Is Used
Machine Changeover
Dial in the 580-600 mm retract stop during product size transitions without replacing the cylinder or bolting on external stops.
End-Position Tuning
Fine-tune the exact retraction point at commissioning to perfectly align parts on a 600 mm stroke conveyor handling system.
Heavy Assembly Press
Leverage the 4523 N push force at 0.9 MPa to seat heavy components, using the rear adjuster to prevent over-travel.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-20 the Right Cylinder?
Choose this 80 mm bore when an application requires significantly more thrust than the 50 mm bore provides (1767 N push at 0.9 MPa), but without stepping up to the 100 mm bore and its 7068 N output. The adjustable stroke is ideal for machine setup and product changeover, allowing you to fine-tune the retract position at commissioning rather than swapping the cylinder for a fixed-stroke SAI variant.
Because this is a 600 mm stroke, the M20x1.5 rod will experience amplified side loads if the load is unsupported; an external guide is recommended. The rear adjuster acts only as a travel stop and does not hold the load without live air—use a SAIL or BSAI cylinder for fail-safe locking. This model uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).
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 SAIJ80AX600-20 FAQ
At 0.9 MPa, this 80 mm bore cylinder provides a push force of 4523 N and a pull force of 3681 N. At the maximum operating pressure of 1.0 MPa, it reaches 513 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 20 mm, creating a usable travel window of 580 to 600 mm. This lets you set the exact retract position during commissioning without changing the cylinder.
