About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X290-10
The AirTAC SAIJ80X290-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 2513N of push force at 0.5 MPa. It features a 25mm carbon steel rod and a G3/8 PT port. By turning the external stopper screw, you can fine-tune the effective travel within a 280-290mm window, eliminating the need to swap hardware during commissioning.
This 80mm bore actuator operates at speeds of 30-800mm/s and relies on adjustable air cushions at both ends to decelerate the load. The extruded aluminum barrel includes sensor grooves on both sides, ready to accept CMSE reed or DMSE electronic switches if a magnet is specified later. Remember that the rear adjuster functions strictly as a travel stop, not a locking device, so it will not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X290-10 Is Used
Machine Setup Calibration
Dial in the exact 280-290mm end position during initial commissioning to perfectly align heavy clamping fixtures without machining new spacers.
Product Changeover
Quickly adjust the stroke endpoint by up to 10mm on a packaging line when switching to a slightly different carton size, minimizing downtime.
Variable End Stops
Use the rear stopper screw to trim the retract position precisely, ensuring delicate components are pushed into place without crushing them.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X290-10 the Right Cylinder?
Choose this 80mm bore when an application requires substantial thrust, such as the 2513N push force at 0.5 MPa, but does not need the full 3927N output of a 100mm cylinder. The 10mm adjustment range is ideal for dialing in exact end positions during machine setup or product changeovers without adding external stops. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead, as the SAIJ adjuster only sets the travel endpoint.
Because this model has a 290mm stroke, the 25mm rod and M20x1.5 thread provide robust support, but an external guide is still recommended to prevent excessive side-loading on the piston. To match this cylinder for an ISO 15552 replacement, verify the 290mm stroke, 10mm adjustment, G3/8 PT port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAIJ80X290-10 FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.7 MPa, the push force increases to 3518N.
The rear adjuster acts as a mechanical stop that allows you to shorten the nominal 290mm stroke by up to 10mm, providing a usable travel window of 280-290mm for fine-tuning end positions without replacing the cylinder.
