About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX185-10S
The AirTAC SAIJ80X185-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. The integrated -S magnet supports position sensing with AirTAC CMSE reed and DMSE electronic switches.
This specific SKU provides a 185mm nominal stroke that can be dialed back by up to 10mm, creating a 175-185mm usable travel window. This built-in adjuster acts as a mechanical stop to fine-tune the retract end-position at commissioning without adding external stops. It features G3/8 PT ports and self-compensating air cushions at both ends to manage deceleration.

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 SAIJ80BX185-10S Is Used
Machine Changeover
Dial in the 175-185mm travel window during product size changes on a conveyor line without physically replacing the actuator.
Commissioning Calibration
Fine-tune the retract end-position during initial setup to perfectly align a 2513N pressing or pushing motion.
Adjustable End-Stop
Use the 10mm rear mechanical stop to compensate for mechanical wear or slight material thickness variations over time.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX185-10S the Right Cylinder?
The 10mm rear adjuster is ideal for machine setup or product changeover, allowing you to shift the end-stop dynamically rather than swapping a fixed-stroke SAI cylinder.
If you need to step down force, the 63mm bore offers 1559N at 0.5MPa; stepping up to 100mm yields 3927N. For load-holding without live air pressure, note that the SAIJ rear adjuster and air cushions only set travel and deceleration—they do not lock the load. For true locking, choose the SAIL or BSAI series. To match this ISO 15552 interchangeable cylinder, specify: 80mm bore, 185mm stroke, 10mm adjustment, G3/8 PT ports, SUS304 rod, and -S magnet.
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 SAIJ80BX185-10S FAQ
The maximum thrust is 513 kgf at 1.0MPa.
The rear adjuster acts as a mechanical stop that allows you to shorten the 185mm nominal stroke by up to 10mm, providing a usable travel window of 175-185mm. It sets the end position but does not lock the load without live air pressure.
