Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-50
The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-50 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 600mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-50
The AirTAC SAIJ80X600-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 50 mm. This creates a usable 550-600 mm end-position window, letting you dial in the exact retract distance during commissioning without swapping out the barrel or adding external stops. With a 25 mm piston rod and a robust 4523N thrust at 0.9 MPa, it handles substantial loads while maintaining the standard ISO 15552 mounting footprint.
This unit utilizes a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance and features PT tapered port threads (G3/8). The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. The rear adjuster functions strictly as a travel stop to set deceleration and end limits; it does not hold the load without live air pressure, so applications requiring true load-holding should utilize an SAIL pneumatic lock or BSAI clamp-lock cylinder.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-50 Is Used
Variable End-Stop Tuning
Dial in the exact 550 to 600 mm retract distance during machine setup to accommodate different product lengths without physically remounting the cylinder.
Product Changeover Lines
Quickly adjust the stroke stop on packaging or conveying lines to handle varying package sizes, reducing downtime between production runs.
Long-Stroke Assembly Presses
Leverage the 4523N push force at 0.9 MPa for pressing operations, using the rear screw to fine-tune the final end-position without external shims.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-50 the Right Cylinder?
Choose this 80 mm bore when your application requires more force than a 63 mm cylinder (which provides 1402N pull at 0.5 MPa) but you want to avoid the larger footprint and higher air consumption of a 100 mm bore. The 50 mm adjustment range is particularly useful on long 600 mm strokes, allowing you to fine-tune variable end stops for product size changeovers on a line. Because the stroke extends to 600 mm, the unsupported load is susceptible to deflection and side-loading; an external guide rail system is highly recommended to prevent premature seal wear.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 600 mm stroke, 50 mm adjustment, PT G3/8 port, and required mounting accessory from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted from this adjustable series. The rear stopper is not a brake—never rely on it to hold a suspended load without continuous air pressure.
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 SAIJ80AX600-50 FAQ
At 0.5 MPa it provides 2513N push and 2268N pull force. At 0.9 MPa, the push force increases to 4523N.
The rear adjuster screw acts as an external stopper that shortens the 600 mm nominal stroke by up to 50 mm, giving a usable 550-600 mm travel window. It sets the end position but does not lock the load without air pressure.
