Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-50
The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-50 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 SAIJ80X1000-50
The AirTAC SAIJ80X1000-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster, built with a carbon steel piston rod and PT tapered ports. Because the 1000 mm stroke exceeds the standard 1500 mm limit for this bore, it is supplied as a made-to-order nonstandard assembly. It delivers a robust 3518N push force at 0.7MPa and provides a usable travel window of 950 to 1000mm, allowing you to dial back the retract position by up to 50mm.
This adjustable-stroke design lets you fine-tune the end position during commissioning or product changeover without swapping the barrel or adding external stops. The extruded aluminum profile includes sensor grooves on both sides for CMSE reed and DMSE electronic switches, though this non-magnetic variant requires a -S suffix for sensor compatibility. The rear screw acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-50 Is Used
Variable End-Stop Machining
Dial in the exact retract position within the 950-1000mm window to accommodate different raw material lengths on a single fixture.
Product Changeover Gates
Quickly reposition a diverter arm by up to 50mm during packaging line size transitions without physically remounting the actuator.
Long-Stroke Assembly Presses
Leverage the 80mm bore's 3518N thrust at 0.7MPa for long-travel pressing operations that require fine-tuning the final clamp position.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-50 the Right Cylinder?
Choose this 80mm bore when an application requires heavy thrust beyond the 63mm class (2182N at 0.7MPa) but less than the 100mm class (5497N at 0.7MPa). The 50mm adjustment window is ideal for machinery that requires variable end-stops for different product sizes. For load-holding without continuous air pressure, select the SAIL or BSAI series instead, as the SAIJ rear adjuster is a stop, not a lock. To replace an ISO 15552 cylinder, match the 80mm bore, 1000mm stroke, 50mm adjustment, G3/8 port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting.
At 1000mm of travel, the 25mm rod and M20x1.5 thread provide structural stability, but the long unsupported length demands an external guide to prevent excessive side loading and premature wear.

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 SAIJ80X1000-50 FAQ
The rear adjuster screw lets you shorten the effective travel from the 1000mm nominal stroke down to 950mm, providing a 50mm tuning window to set the exact retract end-position without external stops.
At 0.7MPa operating pressure, the SAIJ80X1000-50 provides a push force of 3518N and a pull force of 2268N. At 0.5MPa, it delivers 2513N push and 2268N pull.
