Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-20
The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-20 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 1000mm 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 SAIJ80X1000-20
The AirTAC SAIJ80X1000-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the 1000mm nominal stroke back by up to 20mm. This yields a usable travel window of 980-1000mm, allowing precise end-position tuning at commissioning without swapping the cylinder or adding external stops. The 80mm bore delivers 4523N of push force at 0.9MPa, placing it firmly in the heavy-duty class for high-load automation.
The extruded aluminum barrel includes sensor grooves on both sides for CMSE and DMSE switches, though this specific configuration omits the -S magnet. It uses a robust 25mm carbon steel rod with an M20x1.5 thread, and the PT tapered port is G3/8. The rear adjuster acts solely as a travel stop to set the retract end position, meaning it does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-20 Is Used
Long-Stroke Press Tuning
Dial in the exact 980-1000mm retract stop during machine setup to accommodate varying material thicknesses without external shims.
Product Changeover Stops
Adjust the end-position on the fly when switching conveyor line product sizes, saving the downtime of physically swapping cylinders.
Heavy Load Positioning
Leverage the 4523N push force at 0.9MPa to move heavy pallets or chassis, using the rear screw to fine-tune the final resting position.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-20 the Right Cylinder?
Choose this 80mm bore when 50mm (1374N push at 0.5MPa) is too weak but the 100mm (5497N push at 0.7MPa) is physically oversized. The adjustable stroke is ideal for product changeovers or fine-tuning a long-travel end stop, whereas a fixed SAI cylinder lacks this commissioning flexibility. Because the 1000mm stroke is substantial, the 25mm rod still requires an external guide to prevent side-load damage over such a long unsupported span.
For an exact ISO 15552 replacement, match the 80mm bore, 1000mm stroke, 20mm adjustment, G3/8 PT port, and carbon steel rod. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, intentionally omitting FB, CA, CB, and CR. If your application requires true load-holding without live air, skip this model and look to the SAIL or BSAI series.

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 SAIJ80X1000-20 FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 1000mm stroke by up to 20mm. This creates a 980-1000mm usable travel window for fine-tuning the retract end position at commissioning. It functions only as a stop and does not lock the load without air pressure.
At 0.9MPa, this 80mm bore cylinder provides 4523N of push force and 4071N of pull force. At the maximum operating pressure of 1.0MPa, it delivers up to 513kgf (5030N) of push force.
