About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX1000-30
The AirTAC SAIJ80X1000-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 970 to 1000 mm usable travel window by dialing back the nominal 1000 mm stroke up to 30 mm via the external stopper screw. This 80 mm bore generates 2513 N of pull force at 0.5 MPa and 4523 N at 0.9 MPa, making it a robust choice for heavy-duty positioning.
Built with a SUS304 stainless steel rod and PT tapered ports, this unit omits the FB, CA, CB and CR mounting options, supporting only the Basic, FA, LB, TC, FTC, TCM1 and TCM2 interfaces. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is configured without a magnet for position sensing.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX1000-30 Is Used
Machine Changeover
Dial in the exact 970 to 1000 mm end position during product size changes on a packaging line without physically swapping the cylinder.
Long-Stroke Positioning
Provides robust 4523 N push force at 0.9 MPa for moving heavy jigs over a 1-meter travel distance with adjustable end-stops.
Assembly Line Tuning
Fine-tune the retract position during commissioning to align large parts perfectly, avoiding the cost of custom machined spacers.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX1000-30 the Right Cylinder?
Select this 80 mm bore when an application requires substantial thrust but demands fine-tuning of the end position during commissioning without adding external stops. If you need less force, stepping down to a 63 mm bore yields 1402 N of pull at 0.5 MPa. Because this model features a 1000 mm stroke, the 25 mm rod diameter and M20x1.5 thread carry significant side loads, so an external guide is strongly recommended to prevent rod binding.
The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL pneumatic lock or BSAI clamp-lock series. This cylinder is dimensionally interchangeable per ISO 15552 and uses a PT port thread.
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 SAIJ80BX1000-30 FAQ
At 0.5 MPa it provides 2513 N of pull force and 2268 N of push force. At 0.9 MPa the push force increases to 4523 N.
The rear adjuster screw lets you shorten the effective travel from 1000 mm down to 970 mm. It functions as a mechanical stop to fine-tune the retract position and is not a lock that holds the load without air pressure.
