About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X290-10
The AirTAC SAIJ100X290-10 is a double-acting ISO 15552 profile cylinder featuring a rear-located stroke adjuster. It delivers a robust 3927N push force at 0.5 MPa and provides a usable travel window of 280 to 290 mm, allowing you to dial back the nominal stroke by up to 10 mm. This fine-tuning capability at commissioning eliminates the need to swap the entire cylinder or bolt on external stops when aligning end positions.
Equipped with a 25mm carbon steel piston rod and an M20x1.5 rod thread, this bore size handles substantial loads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE solid-state switches. It features PT tapered G1/2 ports, variable air cushions at both ends to manage kinetic energy, and operates at speeds between 30 and 800 mm/s.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X290-10 Is Used
Machine Setup & Calibration
Dial in the exact 280 to 290 mm end-position during machine commissioning without machining new spacers or swapping the actuator.
Product Changeover
Quickly adjust the retract stop by up to 10 mm on packaging lines running slightly different product sizes to maintain accurate positioning.
Heavy Assembly Pressing
Leverage the 3927N push force at 0.5 MPa for high-load pressing tasks while using the rear screw to fine-tune the final contact position.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X290-10 the Right Cylinder?
Select this 100mm bore actuator when an application requires high thrust combined with precise end-position tuning. If your setup demands less force, stepping down to the 80mm bore yields 2513N of push force at 0.5 MPa, whereas moving up to the 125mm bore provides 6136N for heavier loads. The SAIJ series is chosen over a fixed-stroke SAI cylinder when product changeovers require a variable end-stop rather than a rigid, fixed travel length.
Because the nominal stroke is 290mm, an external guide is recommended to prevent excessive side-loading on the extended rod. For dimensionally interchangeable ISO 15552 replacements, match the 100mm bore, 290mm stroke, 10mm adjustment, PT G1/2 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series.
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 SAIJ100 Adjustable Cylinder SAIJ100X290-10 FAQ
At an operating pressure of 0.5 MPa, this 100mm bore cylinder provides a push force of 3927N and a pull force of 3681N. At the maximum 1.0 MPa, it delivers up to 801 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the 290mm nominal stroke down to 280mm. It sets the retract end-position but does not lock the load without continuous air pressure.
