About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX30-10
The AirTAC SAIJ80X30-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position at commissioning. With a nominal 30 mm stroke and a 10 mm adjustment range, it provides a usable travel window of 20-30 mm without needing external stops. It delivers a robust 4523 N push force at 0.9 MPa, making it ideal for heavy-duty positioning tasks.
This variant is equipped with a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and uses PT tapered port threading. The extruded aluminum barrel includes sensor grooves on both sides, ready for AirTAC CMSE reed and DMSE solid-state switches if you add a magnet later. It supports the standard SAIJ mounting set, including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX30-10 Is Used
Machine Setup Changeover
Fine-tune the 20-30 mm travel window during product line changeovers to perfectly position stops without machining new brackets.
Variable End-Stop Tuning
Dial in the exact retraction point during commissioning using the rear screw, eliminating the need to bolt on external physical stops.
Heavy-Duty Positioning
Leverage the 4523 N push force at 0.9 MPa to move heavy jigs or fixtures into a precise final location before clamping.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX30-10 the Right Cylinder?
Choose this 80 mm bore cylinder when an application requires high force—stepping down to a 63 mm bore yields 2805 N push at 0.9 MPa, whereas this model provides 4523 N. The adjustable stroke is perfect for machine setups requiring variable end-stops or product-size changeovers, avoiding the need to swap out a fixed-stroke SAI cylinder. Because the rear adjuster acts only as a travel stop and the air cushions handle deceleration, this cylinder will not hold a load without live air pressure; for true load-holding, consider the SAIL or BSAI series.
When replacing an ISO 15552 cylinder, verify the 80 mm bore, 30 mm nominal stroke, 10 mm adjustment range, G3/8 port, and your required mounting style. The 25 mm rod diameter and M20x1.5 rod thread provide excellent rigidity, though any long unsupported stroke still requires an external guide to prevent side-load damage.
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 SAIJ80AX30-10 FAQ
At 0.9 MPa operating pressure, this 80 mm bore cylinder provides a push force of 4523 N and a pull force of 3681 N. At 0.5 MPa, the push force is 2513 N.
The rear adjuster screw lets you shorten the effective stroke by up to 10 mm. For this 30 mm nominal stroke model, it creates an adjustable travel window of 20-30 mm so you can set the exact end position during setup.
