About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX165-40
The AirTAC SAIJ80X165-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a usable travel window of 125 to 165 mm. This configuration uses a SUS304 stainless steel rod for superior corrosion resistance.
It features PT tapered port threads (G3/8) and variable air cushions at both ends to decelerate moving masses smoothly. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ80BX165-40 Is Used
Variable End-Stop Positioning
Dial in the exact retract distance between 125 and 165 mm on machining fixtures to accommodate multiple part sizes without changing tooling.
Machine Commissioning
Fine-tune the final end position during setup to clear mechanical interference, using the rear screw rather than reworking mountings.
Product Changeover
Quickly adjust the stroke length on packaging lines when transitioning to different box widths, ensuring precise stops without external hardware.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX165-40 the Right Cylinder?
The 40 mm adjustment range is ideal for fine-tuning end positions during machine commissioning or product changeover without swapping cylinders or adding external stops. For load-holding without live air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ rear adjuster is a travel stop, not a lock.
To replace an ISO 15552 cylinder, match the 80 mm bore, 165 mm stroke, 40 mm adjustment, PT G3/8 port, and the desired mounting kit. Because the stroke is under 300 mm, side-load stress is moderate, but long unsupported loads should still use an external guide to protect the rod.
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 SAIJ80BX165-40 FAQ
At the maximum 1.0 MPa pressure, it provides 513 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 165 mm nominal stroke by up to 40 mm. This creates a usable travel window of 125 to 165 mm for precise end-position tuning at commissioning.
