About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-20S
The AirTAC SAIJ80X1000-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 2513N of push force at 0.5 MPa and features a 1000 mm nominal stroke that can be fine-tuned down by up to 20 mm, providing a usable travel window of 980-1000 mm for precise commissioning. This variant includes a standard carbon steel piston rod and a built-in magnet for electronic DMSE or reed CMSE position sensing.
The rear adjuster acts purely as a mechanical stop to dial in the end position without adding external stops or swapping the cylinder. Because this is a 1000 mm stroke unit, an external guide is highly recommended to prevent rod sag and manage side loads. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-20S Is Used
Long-Stroke Machine Setup
Dial in the exact end-of-travel position within the 980-1000 mm window during equipment commissioning without installing external physical stops.
Product Size Changeover
Quickly adapt the retract position on a conveyor handling varying package lengths by turning the rear adjuster screw during line changeovers.
Variable End-Stop Positioning
Provide a mechanical stop for long-travel assemblies that need precise end-position tuning on the fly while maintaining a standard ISO 15552 footprint.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-20S the Right Cylinder?
Select this 80 mm bore when an application requires roughly 2513N of push force at 0.5 MPa, stepping up from a 63 mm bore that provides 1559N. The adjustable stroke is chosen when you need variable end-stops for product changeovers or fine-tuning at commissioning, rather than a fixed-stroke SAI cylinder. It uses a PT tapered port and includes the -S magnet option for CMSE/DMSE sensors.
For any stroke of 1000 mm, always support the load with an external guide to handle side loads, as the 25 mm rod can only carry so much cantilevered weight. The rear adjuster and air cushions decelerate the travel end but do not hold the load without live air; for true load-holding without pressure, use an external rod lock or point to the SAIL or BSAI series.
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 SAIJ80X1000-20S FAQ
The rear adjuster screw lets you shorten the 1000 mm nominal stroke by up to 20 mm, giving an effective travel window of 980 to 1000 mm. It acts as a mechanical stop to fine-tune the retract position without swapping cylinders.
At 0.5 MPa operating pressure, it provides 2513N of push force and 2268N of pull force. At 0.7 MPa, the push force increases to 3518N.
