About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-100
The AirTAC SAIJ80X230-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 100 mm. This yields a wide 130-230 mm usable window, letting you dial in the exact retract position at commissioning without swapping hardware. It delivers a robust 2513 N pull force at 0.5 MPa, making it well-suited for heavy manipulation tasks.
Equipped with a 25 mm carbon steel rod and an M20x1.5 thread, this unit handles greater side loads than smaller bores, though external guidance is still recommended for long unsupported overhangs. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches. It uses a PT tapered port (G3/8) and relies on adjustable air cushions at both ends to decelerate the load smoothly.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-100 Is Used
Variable End-Stop Tuning
Leverage the 130-230 mm travel window to set precise retract positions for different product sizes without adding external mechanical stops.
Heavy Forming & Pressing
Utilize the 2513 N pull force at 0.5 MPa for robust clamping and forming operations that require exact end-position control.
Machine Changeover
Rapidly adjust the cylinder's effective stroke during product line changeovers to accommodate varying material lengths on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-100 the Right Cylinder?
Select this 80 mm bore when your application requires higher thrust than a 63 mm cylinder (which provides 1402 N pull at 0.5 MPa) but does not warrant the bulk of a 100 mm unit. The massive 100 mm adjustment range is perfect for product-size changeovers on a line, acting as a variable end-stop that saves you from machining custom spacers or buying multiple fixed-stroke SAI cylinders.
Remember that the rear adjuster and air cushions only manage travel end-deceleration; they do not hold the load without live air. For dead-stop load holding, consider an external pilot-operated check valve or explore the SAIL or BSAI series. This SAIJ model is dimensionally interchangeable per ISO 15552 and uses the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR brackets.

- ✓ 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 SAIJ80X230-100 FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At the maximum operating pressure of 1.0 MPa, it delivers a maximum push force of 513 kgf.
The rear adjuster screw allows you to shorten the 230 mm nominal stroke by up to 100 mm, creating a 130-230 mm usable travel window. It acts as a physical stop to fine-tune the end position, but it is not a lock and will not hold the load without continuous air pressure.
