Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-40
The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-40 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 SAIJ80X1000-40
The AirTAC SAIJ80X1000-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 2513N push force at 0.5 MPa. It features a carbon steel piston rod and PT tapered port threading. This made-to-order unit provides a usable travel window of 960-1000mm, letting you dial in the exact retract position without swapping hardware.
The external stopper fine-tunes the end-of-stroke at commissioning, while the adjustable air cushions handle deceleration over the long 1000mm span. Because the rear adjuster acts only as a mechanical stop, it will not hold a load without live air pressure; for true load-holding, consider an external rod lock or the related SAIL series. Sensor grooves on both sides accept CMSE reed or DMSE electronic switches.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-40 Is Used
Long-Stroke Material Handling
Ideal for pushing heavy pallets or workpieces over a 1000mm span, with the 40mm adjustment allowing precise alignment to varying pallet stop positions.
Machine Changeover Setup
Quickly fine-tune the retract end-position during product size changeovers without physically swapping the cylinder or adding mechanical shims.
Automated Assembly Lines
Provides 2513N of push force at 0.5 MPa for pressing or indexing components, with rear adjustment to dial in the exact stopping point.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-40 the Right Cylinder?
Choose this 80mm bore when an application demands higher thrust than the 63mm bore (1559N at 0.5 MPa) but does not require the massive output of the 100mm bore (3927N). The -40 adjustment code is ideal for product changeovers, allowing you to shift the retract position by up to 40mm without installing external stops or buying a fixed-stroke SAI cylinder. When sourcing an ISO 15552 replacement, match the 80mm bore, 1000mm stroke, G3/8 port, and mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Because the stroke is 1000mm, the 25mm rod and M20x1.5 thread will still experience leverage forces; an external guide is highly recommended to prevent side-loading damage. Note that SAIJ omits the FB, CA, CB, and CR mountings. The cylinder operates at speeds of 30-800mm/s.
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 SAIJ80X1000-40 FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.9 MPa, the push force increases to 4523N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 40mm, creating a usable travel window of 960-1000mm. It sets the end position but does not lock the load without continuous air pressure.
