About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X190-30
The AirTAC SAIJ80X190-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 160 to 190 mm, allowing you to dial back the nominal 190 mm stroke by up to 30 mm during machine commissioning. This 80 mm bore delivers 2513 N of push force and 2268 N of pull force at 0.5 MPa, making it suited for medium to heavy actuation tasks.
The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches. A standard carbon steel rod with an M20x1.5 thread handles high side loads, while the rear adjuster acts purely as a travel stop to set end positions without needing external stops. Air cushions at both ends manage deceleration across the 30-800 mm/s speed range.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X190-30 Is Used
Variable End-Stop Positioning
Dial in the exact retract distance between 160 and 190 mm to accommodate multiple product sizes on a single line without physically replacing the actuator.
Machine Commissioning Tuning
Fine-tune the final end-of-stroke position during setup to prevent mechanical interference, using the 30 mm adjustment range to perfect the motion sequence.
Heavy Fixture Clamping
Leverage the 2513 N push force at 0.5 MPa to secure heavy workpieces, relying on the external stopper to set the precise clamping depth.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X190-30 the Right Cylinder?
Select this 80 mm bore when an application requires precise end-position tuning without swapping hardware; if you need less force, the 63 mm bore offers 1559 N at 0.5 MPa, while the 100 mm bore provides 3927 N for heavier loads. The PT tapered G3/8 port matches the standard sizing for this bore class. Remember that the rear adjuster is a stop, not a lock; the SAIJ80X190-30 cannot hold a load without live air pressure, so for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder instead. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ80X190-30 FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster screw lets you shorten the effective travel from the 190 mm nominal stroke down to 160 mm. It functions as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
