Airtac SAIJ80 Adjustable Cylinder SAIJ80AX60-50
The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80AX60-50 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 60mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX60-50
The AirTAC SAIJ80X60-50 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 10 to 60 mm without swapping hardware. Built with an extruded aluminum barrel and a SUS420J2 stainless steel piston rod, it delivers 3518N of push force at 0.7 MPa, making it well-suited for medium-to-heavy positioning tasks.
This model features PT tapered port threads (G3/8) and lacks a standard magnet, meaning position sensing via CMSE or DMSE switches is not available out of the box. The external rear stopper acts purely as a mechanical travel limit to dial in the exact end-position during commissioning.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX60-50 Is Used
Variable End-Stop Positioning
Dial in precise retract distances from 10 to 60 mm for packaging lines that process varying container sizes on the same conveyor.
Machine Commissioning
Fine-tune the final end-position during setup without machining new hard stops or replacing the entire actuator.
Heavy-Duty Changeover
Leverage 3518N of push force at 0.7 MPa to shift heavier jigs or product stops rapidly between automated production runs.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX60-50 the Right Cylinder?
Choose this 80mm bore when your application requires higher thrust than a 63mm cylinder (which provides 2182N at 0.7 MPa) but does not need the full 5497N push force of a 100mm variant. The 50mm adjustment range is ideal for machinery that frequently handles multiple product sizes, allowing operators to set variable end-stops on the fly instead of installing fixed-stroke SAI cylinders or external stops.
Remember that the rear adjuster is strictly a travel stop, not a locking device; it cannot hold a load without continuous live air pressure. For drop-prevention or fail-safe load holding, consider the SAIL or BSAI series instead. Dimensionally interchangeable with ISO 15552 mounting interfaces, this cylinder supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ80AX60-50 FAQ
At an operating pressure of 0.7 MPa, this 80mm bore cylinder generates 3518N of push force and 2268N of pull force. It can reach a maximum push force of 4523N at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 60mm nominal stroke by up to 50mm, providing a usable travel window of 10 to 60mm. It only sets the end-of-travel position and does not lock or hold the load without live air pressure.
