About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX1000-30S
The AirTAC SAIJ80X1000-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 4523N of push force at 0.9 MPa. It features a SUS304 stainless steel rod and a PT tapered port. With a nominal 1000mm stroke and a 30mm adjustment range, you gain a 970-1000mm usable travel window to perfectly dial in end positions during commissioning.
This made-to-order long-stroke unit includes a magnet for CMSE reed and DMSE electronic sensors. Because the 1000mm stroke is unsupported, the 25mm rod and M20x1.5 thread handle substantial side loads, but an external guide is still recommended. The rear adjuster acts purely as a travel stop for deceleration, not a lock to hold the load without live air.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX1000-30S Is Used
Long-Stroke Changeover
Dial in the 970-1000mm travel window during product size changeovers without physically replacing the cylinder or adding external stopper blocks.
Material Handling
Provides robust 4523N push force for moving heavy pallets or workpieces over extended distances on automated assembly lines.
End-Position Tuning
Fine-tune the exact retract position during machine commissioning to account for mechanical tolerance stack-up over a 1000mm span.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX1000-30S the Right Cylinder?
Choose this 80mm bore when you need more thrust than a 63mm cylinder (which provides 2805N push at 0.9 MPa) but less bulk than a 100mm option. The adjustable 970-1000mm window is ideal for applications requiring variable end-stops or product changeovers, saving you from swapping out a fixed-stroke SAI cylinder. To match this ISO 15552 replacement exactly, specify the 80mm bore, 1000mm stroke, 30mm adjust, PT port, SUS304 rod, and the -S magnet.
For any 1000mm stroke, lateral forces are a primary concern; always pair this cylinder with an external guide to prevent rod binding. Remember that the rear adjuster and air cushions only set the travel end and deceleration. If you need true load-holding without live air pressure, consider an AirTAC SAIL locking cylinder or an external rod lock.
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 SAIJ80BX1000-30S FAQ
At 0.9 MPa operating pressure, this 80mm bore cylinder provides 4523N of push force and 4071N of pull force. It reaches a maximum of 513 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the effective travel by up to 30mm, creating a 970-1000mm usable window. It functions as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
