About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX135-100
It features a SUS304 stainless steel rod and PT tapered ports. By integrating an external adjusting screw, this actuator allows you to fine-tune the effective stroke on the fly, providing a usable travel window of 35 to 135mm without swapping out the entire unit.
Because the adjustment range spans a generous 100mm, operators can dial in the retract end-position during commissioning or product changeovers. The rear stopper simply acts as a travel limit to set the deceleration point alongside the standard air cushions; it does not lock the load without live air pressure. For load-holding requirements without continuous pneumatic pressure, consider an external rod lock or related SAIL and BSAI series.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX135-100 Is Used
Product Changeovers
Rapidly adapt machinery for different package lengths by dialing the rear screw to shift the 35-135mm travel window, eliminating the need for physical stop modifications.
Machine Setup
Achieve precise end-position tuning during initial commissioning using the 100mm adjustment range, ensuring perfect alignment before finalizing the setup.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX135-100 the Right Cylinder?
The extensive 100mm adjustment window makes the SAIJ80X135-100 ideal for prototyping or machinery that processes varying product sizes, allowing the end-stop to be repositioned rapidly rather than machining external stops. If position holding is required when air is removed, note that this adjuster is strictly a stop and a pilot-operated check valve or BSAI clamp-lock cylinder is necessary.
When replacing an ISO 15552 actuator, match the 80mm bore, 135mm nominal stroke, 100mm adjustment, PT port threads, and the specific mounting set. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR options. As this model lacks the -S magnet suffix, it will not trigger AirTAC CMSE or DMSE sensors.
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 SAIJ80BX135-100 FAQ
The rear adjuster screw acts as a mechanical stop that lets you trim the nominal 135mm stroke back by up to 100mm, creating a usable travel window of 35 to 135mm. It sets the end position but does not hold the load without live air pressure.
It operates at speeds between 30 and 800mm/s and features a G3/8 port.
