About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX900-30S
The AirTAC SAIJ80X900-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits up to 30mm of end-position tuning. This yields a usable travel window of 870-900mm, allowing precise calibration during machine commissioning without swapping the hardware. It delivers 2513N push force at 0.5MPa and reaches speeds of 30-800mm/s.
Equipped with a SUS304 stainless steel rod and PT tapered ports, this unit integrates dual-side sensor grooves for CMSE reed and DMSE electronic switches. The extruded aluminum barrel supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX900-30S Is Used
Long-Stroke Forming
Dial in the exact 870-900mm end-stop for large press or forming operations, ensuring precise contact depth during setup.
Product Changeover
Adjust the retract position by up to 30mm on the fly to accommodate different package sizes on a packaging line.
Machine Commissioning
Fine-tune the final end-position without adding external mechanical stops or replacing the installed cylinder.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX900-30S the Right Cylinder?
Choose this 80mm bore when a 50mm bore provides insufficient thrust (982N at 0.5MPa) but a 100mm bore is oversized (3927N at 0.5MPa). The 30mm adjustment range is ideal for variable end-stops during product changeover, providing finer control than a fixed-stroke SAI cylinder. Because the 900mm stroke is long, an external guide is recommended to manage side-load risks on the 25mm rod.
For an exact ISO 15552 replacement, match the 80mm bore, 900mm stroke, PT ports, SUS304 (B) rod material, and the -S magnet option. If load-holding without live air is required, this cylinder is insufficient; consider an SAIL air-released lock or BSAI clamp-lock instead.
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 SAIJ80BX900-30S FAQ
At 0.5MPa it provides 2513N push force and 2268N pull force. At 0.7MPa the push force increases to 3518N, with a maximum push force of 4523N at 0.9MPa.
The rear adjuster screw lets you shorten the nominal 900mm stroke by up to 30mm, creating an adjustable travel window between 870mm and 900mm. It functions as a mechanical stop and does not lock the load without air pressure.
