About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X180-30S
The AirTAC SAIJ80X180-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 150 to 180 mm. It delivers a robust 4523 N push force at 0.9 MPa, making it well-suited for heavy-duty positioning tasks.
This unit features a carbon steel piston rod and a PT tapered port. The integrated magnet (-S) supports position sensing via AirTAC CMSE reed and DMSE electronic switches. It utilizes a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X180-30S Is Used
Machine Changeover
Fine-tune the retract distance by up to 30 mm when switching between product sizes on a packaging line, avoiding physical cylinder swaps.
End-Stop Calibration
Dial in the exact 150-180 mm travel window during commissioning to perfect pressing or clamping positions without external shims.
Heavy Positioning
Leverage the 4523 N push force to move substantial jigs or fixtures, using the adjustable stop to compensate for mechanical wear over time.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X180-30S the Right Cylinder?
Choose this 80 mm bore when you need higher thrust than a 63 mm cylinder (which provides 2805 N push at 0.9 MPa) but do not require the full 7068 N push force of a 100 mm unit. The 30 mm rear adjuster allows you to dial in the exact end-stop during commissioning or product changeover without adding external stops or swapping to a fixed-stroke SAI cylinder.
For load-holding applications without live air pressure, note that the rear adjuster and air cushions act only as travel stops and deceleration, not as a lock. You should consider the SAIL or BSAI series instead. To match this ISO 15552 replacement, specify an 80 mm bore, 180 mm stroke, 30 mm adjustment, PT port, and the -S magnet.
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 SAIJ80X180-30S FAQ
At 0.9 MPa, this 80 mm bore cylinder provides a push force of 4523 N and a pull force of 4071 N. The maximum operating pressure is 1.0 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from 180 mm down to 150 mm. It sets the travel end and works with the air cushion to decelerate the load, but it does not hold the load without live air pressure.
