About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX600-30S
The AirTAC SAIJ80X600-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the effective travel back by up to 30 mm. This creates a usable 570-600 mm stroke window, letting you dial in the exact end position during commissioning without swapping hardware. It delivers a robust 4523 N push force at 0.9 MPa, utilizing a 25 mm piston rod and G3/8 ports.
Equipped with a SUS304 stainless steel rod and a magnet for position sensing, this unit accepts AirTAC CMSE reed and DMSE electronic switches. The extruded aluminum barrel includes sensor grooves on both sides, and the rear stopper simply sets the travel end. It does not lock the load without live air; use a SAIL or BSAI cylinder for pneumatic load-holding.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX600-30S Is Used
Machine Changeover
Fine-tune the 570-600 mm travel end-stop to handle different product sizes on the same line without changing cylinders.
End-Position Tuning
Dial in the exact retract position during commissioning to meet tight tolerances without adding external mechanical stops.
Conveyor Diverter
Adjust the retract distance on the fly to accommodate varying package lengths moving down a material handling belt.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX600-30S the Right Cylinder?
Choose this adjustable model over a fixed SAI when your setup requires fine end-tuning or frequent product-size changeovers. If you need less force, stepping down to a 63 mm bore yields 2805 N push at 0.9 MPa, while moving up to a 100 mm bore provides 7068 N. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.
Because the 600 mm stroke is long, the unsupported load increases lateral stress on the 25 mm rod and M20x1.5 thread. You must use an external guide to prevent side-load damage. For a true ISO 15552 replacement, match the 80 mm bore, 600 mm stroke, 30 mm adjuster, PT tapered ports, and the -S magnet requirement.
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 SAIJ80BX600-30S FAQ
The rear adjuster acts as a mechanical stop, allowing you to shorten the 600 mm nominal stroke by up to 30 mm. This provides a usable travel window of 570-600 mm. The adjuster only sets the end position; it does not hold the load without live air pressure.
At an operating pressure of 0.9 MPa, this 80 mm bore cylinder generates 4523 N of push force and 4061 N of pull force. At 0.5 MPa, it provides 2513 N push and 2268 N pull.
