About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X165-75S
The AirTAC SAIJ80X165-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 90 to 165 mm usable travel window. Delivering 2513 N of push force at 0.5 MPa, it handles heavy positioning tasks while allowing you to fine-tune the retract end without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches.
Equipped with a carbon steel piston rod and an M20x1.5 rod thread, this 80 mm bore unit handles substantial side loads. The rear adjuster acts purely as a travel stop to set deceleration and end-position, not as a load-holding brake. For applications requiring position holding without live air, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X165-75S Is Used
Variable Product Forming
Dial the rear stopper back by up to 75 mm to accommodate different material lengths on a forming line without physically changing the cylinder.
Changeover Commissioning
Fine-tune the 90 to 165 mm travel window during machine setup to hit exact end positions, eliminating the need for external stopper blocks.
Dynamic Diverter Arms
Provides 2513 N of push force at 0.5 MPa to actuate heavy sorting gates, with the rear stop ensuring consistent retract positions.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X165-75S the Right Cylinder?
Choose this 80 mm bore when a 50 mm bore (982 N at 0.5 MPa) lacks the thrust for your tooling but a 100 mm bore (3927 N) is oversized. The 75 mm adjustment range is ideal for machinery processing variable product sizes, letting operators dial in the retract position during changeovers rather than swapping cylinders. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
This configuration uses PT tapered ports and includes a magnet for DMSE solid-state sensors. Because the 165 mm stroke is under 300 mm, side-load stress is manageable, though long unsupported loads should still use an external guide. To replace an ISO 15552 cylinder, match the 80 mm bore, 165 mm stroke, 75 mm adjustment, PT port, 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 SAIJ80X165-75S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force. It can deliver up to 4523 N at 0.9 MPa.
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. It functions as an end-position stop and does not lock the load without live air.
