About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X165-75
The AirTAC SAIJ80X165-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits a usable travel window of 90 to 165 mm. Delivering 2513 N of push force at 0.5 MPa, it utilizes a 25 mm carbon steel rod and an M20x1.5 thread to handle substantial side loads. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position feedback.
This model uses PT tapered G3/8 ports and variable air cushions at both ends to decelerate the payload smoothly. The rear adjustment mechanism acts strictly as a travel stop for end-position tuning during commissioning; it does not hold the load without live air pressure. For dead-stop load-holding requirements, an external rod lock or the AirTAC SAIL series is required.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X165-75 Is Used
Product Changeovers
Dial in the 90-165 mm travel window during format changes on packaging lines without physically replacing the cylinder or adding external stopper blocks.
End-Position Tuning
Fine-tune the retract end-stop at commissioning to perfectly time the 2513 N push force against varying mechanical stops.
Assembly Machine Setup
Adjust the stroke on the fly to accommodate different part sizes on automated assembly fixtures, leveraging the ISO 15552 mounting footprint.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X165-75 the Right Cylinder?
Choose this 80 mm bore when an application requires higher thrust than a 63 mm cylinder (which provides 1559 N push at 0.5 MPa) but does not need the full 3927 N output of a 100 mm unit. The 75 mm adjustment range is ideal for product changeovers, allowing operators to dial in the exact end-stop without swapping hardware. Unlike a fixed-stroke SAI cylinder, this SAIJ variant provides a 90-165 mm window for fine-tuning during machine setup.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 165 mm stroke, PT G3/8 port, and the standard carbon steel rod. The available mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 165 mm stroke is below the 300 mm threshold, external guide support is less critical, though the 25 mm rod diameter still accommodates notable side loads. Position-holding without live air requires a separate pilot-operated check valve or a BSAI clamp-lock cylinder.
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 SAIJ80X165-75 FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 513 kgf.
The rear adjuster screw lets you shorten the 165 mm nominal stroke by up to 75 mm, creating a usable travel window of 90 to 165 mm. The adjuster functions as a mechanical stop and does not lock or hold the load without continuous air pressure.
