Airtac SAIJ80 Adjustable Cylinder SAIJ80BX50-10
The AirTAC SAIJ80 Adjustable Cylinder SAIJ80BX50-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 50mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX50-10
It features a SUS304 stainless steel rod for superior corrosion resistance and operates at speeds between 30 and 800 mm/s. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
With a 50mm nominal stroke and a 10mm adjustment range, this model provides a usable travel window of 40 to 50mm. This allows you to dial in the exact retract position during commissioning without swapping the cylinder. The rear screw acts as a travel stop to set the end position, but it is not a lock; the cylinder cannot hold a 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 SAIJ80BX50-10 Is Used
End-Stop Calibration
Fine-tune the 40-50mm retract position during machine setup to achieve precise clamping without mechanical shims.
Product Changeover
Quickly adjust the stroke end by up to 10mm to accommodate slight variations in incoming part sizes on the line.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX50-10 the Right Cylinder?
The adjustable 40-50mm window is ideal for applications requiring precise end-position tuning during product changeovers, avoiding the need to bolt on external stops or buy a fixed-stroke SAI cylinder. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead.
To match this ISO 15552 interchangeable cylinder, confirm the 80mm bore, 50mm stroke, 10mm adjustment, PT tapered port thread, and your required mounting set (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Note that this unit lacks a magnet, so it cannot use CMSE or DMSE sensors unless specified with an -S suffix.
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 SAIJ80BX50-10 FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 10mm. This creates a usable travel window of 40 to 50mm, enabling fine-tuning of the end position at commissioning without replacing the cylinder.
