About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX700-10S
The AirTAC SAIJ80X700-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 690-700 mm usable travel window, allowing you to dial back the nominal 700 mm stroke by up to 10 mm during machine setup. This bore delivers 2513 N of pull force at 0.5 MPa, fitting robust handling tasks.
Built with a SUS304 stainless steel rod (code B), it resists corrosion while carrying high side loads. The barrel includes sensor grooves on both sides for CMSE reed and DMSE electronic switches. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX700-10S Is Used
Variable End Stops
Set precise retract positions on a long-stroke conveyor diverter without physically remounting the actuator.
Machine Setup Tuning
Dial in the exact 690 to 700 mm travel window during commissioning to perfect machine timing and avoid hard crashes.
Product Size Changeover
Quickly adapt automated line tooling for different product lengths by adjusting the rear stopper screw up to 10 mm.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX700-10S the Right Cylinder?
Choose this adjustable-stroke model over a fixed SAI when you need fine end-position tuning at commissioning without swapping cylinders or adding external stops. The 700 mm stroke is substantial; despite the 25 mm rod and M20x1.5 thread handling side loads well, long unsupported travel requires an external guide to prevent rod bending.
This cylinder is dimensionally interchangeable per ISO 15552. It uses PT tapered ports (G3/8), operates at 30-800 mm/s, and includes a magnet for position sensing. Note that the rear adjuster and air cushions only set travel ends; they do not hold the load without live air. For load-holding, use SAIL or BSAI.
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 SAIJ80BX700-10S FAQ
At 0.5 MPa it provides 2513 N of pull force and 3518 N of push force. At 0.7 MPa, the push force reaches 3518 N.
The rear adjuster screw lets you shorten the 700 mm stroke by up to 10 mm, creating a 690-700 mm travel window for fine-tuning the end position without changing the cylinder.
