About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX180-100S
The AirTAC SAIJ80X180-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel anywhere within an 80 to 180 mm window. The B-code designation specifies a SUS304 stainless steel rod, which is highly beneficial in humid or mildly corrosive settings.
This unit includes a magnet for position sensing and is fully compatible with AirTAC CMSE reed and DMSE electronic solid-state switches. It utilizes PT tapered port threads (G3/8) and relies on a 36 mm air cushion at both ends to decelerate the load. The rear adjuster acts purely as a mechanical stop to set the end position; it does not hold the load without live air pressure.

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 SAIJ80BX180-100S Is Used
Variable End-Stop Configuration
Perfect for packaging lines that process varying carton sizes, allowing the 80 mm bore to dial back the stroke from 180 mm down to 80 mm on the fly.
Machine Setup & Commissioning
Fine-tune the retract end-position during initial commissioning without machining custom spacers or bolting on external physical stops.
Corrosive Environment Actuation
The SUS304 stainless steel rod makes this adjustable cylinder well-suited for food processing or washdown environments where standard carbon steel rods would pit.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX180-100S the Right Cylinder?
Choose this 80 mm bore when an application requires high thrust but the exact final end-position fluctuates during product changeovers. If you need less force, stepping down to a 63 mm bore drops the push force to 1559 N at 0.5 MPa, whereas a 100 mm bore increases it to 3927 N. The 100 mm adjustment range is ideal for machines running multiple product sizes on a single line, allowing operators to dial in the stroke without swapping cylinders or adding external stops.
For exact ISO 15552 interchangeability, match the 80 mm bore, 180 mm nominal stroke, PT port type, and the -S magnet requirement. Because the nominal stroke is 180 mm, an external guide is recommended if side loads are present. Remember that for load-holding without continuous air pressure, you must look to the SAIL pneumatic lock or BSAI clamp-lock series, as the SAIJ adjuster is a travel stop, not a brake.
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 SAIJ80BX180-100S FAQ
At the maximum pressure of 1.0 MPa, it can deliver up to 513 kgf.
The rear adjuster screw lets you shorten the effective stroke by up to 100 mm, creating a usable travel window between 80 mm and 180 mm. This adjuster functions only as a mechanical stop to set the end position and does not lock or hold the load without live air pressure.
