About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX1000-40S
The AirTAC SAIJ80X1000-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 960 to 1000 mm. It delivers a robust 2513 N pull force at 0.5 MPa, making it well-suited for heavy-duty positioning tasks. Because the stroke exceeds the standard 1500 mm maximum for this bore, it is manufactured as a non-standard made-to-order unit.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing with CMSE reed or DMSE electronic switches. The rear adjustment screw acts purely as a mechanical stop for end-position tuning; it does not hold the load without live air pressure. For load-holding requirements without continuous air, an external rod lock or the SAIL series is required.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX1000-40S Is Used
Variable End Stops
Dial in the exact extended position within the 960-1000 mm window during machine setup, allowing rapid adaptation to different product lengths without swapping cylinders.
Product Changeover
Quickly adjust the rear stopper on long-stroke conveying lines to accommodate new package sizes or material feeds on the fly.
Heavy-Duty Positioning
Leverage the 2513 N pull force at 0.5 MPa to move heavy pallets or fixtures, using the rear screw to fine-tune the final resting position.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX1000-40S the Right Cylinder?
Choose this 80 mm bore if your application requires the 2513 N pull force at 0.5 MPa, stepping up from a 63 mm bore that provides 1402 N. The 40 mm adjustment range is ideal for fine-tuning the extended end position during machine commissioning or product changeover without adding external stops. To match this ISO 15552 replacement exactly, specify: 80 mm bore, 1000 mm stroke, 40 mm adjustment, PT tapered ports, and the -S magnet option.
At a 1000 mm stroke, the 25 mm rod and M20x1.5 thread provide substantial rigidity, but the long unsupported travel necessitates an external guide to prevent excessive side-loading and premature wear. Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ80BX1000-40S FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of pull force and 3518 N of push force. It can achieve a maximum push force of 4523 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective travel from the nominal 1000 mm down to 960 mm. This mechanical stop fine-tunes the end position during commissioning but does not lock the load without live air pressure.
