About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX80-10
The AirTAC SAIJ100X80-10 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear mechanical stopper for stroke modification. It delivers a robust 3927N push force at 0.5 MPa and features a 70-80mm usable travel window, allowing you to trim up to 10mm off the nominal 80mm stroke during machine setup.
This unit is built with a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. It supports a 30-800mm/s speed range and uses the standard SAIJ mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX80-10 Is Used
Machine Changeover
Dial in the exact 70-80mm end position during product size changes without swapping the physical cylinder or repositioning hard stops.
Assembly Pressing
Apply up to 3927N of push force at 0.5 MPa for pressing pins or rivets, using the 10mm adjustment to set precise bottoming depth.
Variable End Stops
Fine-tune the retract stroke on packaging equipment where downstream tooling requires slight positional shifts for different batch runs.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX80-10 the Right Cylinder?
Select this 100mm bore actuator when an 80mm stroke requires exact end-position tuning at commissioning without adding external stops. If your application needs less force, stepping down to a 63mm bore yields 1559N push at 0.5 MPa. Remember that the rear adjuster acts only as a travel stop; it cannot hold a load without live air. For load-holding requirements, consider the SAIL or BSAI series.
When replacing an ISO 15552 cylinder, match the 100mm bore, 80mm stroke, 10mm adjustment, PT port, and SUS304 rod material. Because the stroke is under 300mm, side-load stress is minimal, but always ensure the load is guided on long extensions to protect the rod seals.
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 SAIJ100 Adjustable Cylinder SAIJ100BX80-10 FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.9 MPa, the push force increases to 7068N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from 80mm down to 70mm. This creates a 70-80mm usable window for fine-tuning end positions at commissioning without replacing the cylinder.
