About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X160-100
The AirTAC SAIJ80X160-100 is a double-acting ISO 15552 profile cylinder featuring a rear adjuster screw that allows you to trim the effective stroke by up to 100 mm. This yields a wide usable travel window of 60 to 160 mm, letting you dial in the exact retract position at commissioning without swapping out the barrel or adding external stops. It delivers 2513 N of push force at 0.5 MPa and uses a G3/8 port.
The 25 mm carbon steel piston rod and M20x1.5 thread provide robust resistance to side loads, while the extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch placement. You can mount it using Basic, FA, LB, TC, FTC, TCM1, or TCM2 accessories, omitting the bulkier FB and CA styles. The rear stopper only sets the travel end and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X160-100 Is Used
Product Changeover Dials
Quickly reconfigure the retract stop from 60 to 160 mm to accommodate varying package sizes on a packaging line without disassembling the actuator.
End-Position Trimming
Fine-tune the final retract position during machine setup to precisely mate parts, eliminating the need to bolt on secondary physical stops.
Variable Forming Stops
Adjust the stroke window on the fly for metal forming or bending operations that require different material depths per production run.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X160-100 the Right Cylinder?
Choose this 80 mm bore when an application requires substantial thrust—stepping down to a 63 mm bore drops the 0.5 MPa push force to 1559 N, while a 100 mm bore increases it to 3927 N. The SAIJ80X160-100 is selected over a fixed SAI cylinder when a machine undergoes frequent product changeovers and needs a variable end-stop rather than a locked stroke. To match this ISO 15552 replacement exactly, specify the 160 mm stroke, 100 mm adjustment, PT tapered port threads, and standard carbon steel rod. Because the stroke is under 300 mm, side-load concerns are minimal, but an external guide remains recommended for heavy lateral payloads. For load-holding without live air, this cylinder is not a lock; you would need an external pilot-operated check valve or a related BSAI clamp-lock model.

- ✓ 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 SAIJ80X160-100 FAQ
At 0.5 MPa, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At the maximum operating pressure of 1.0 MPa, it can deliver up to 513 kgf.
The rear adjuster screw lets you shorten the 160 mm nominal stroke by up to 100 mm, creating an adjustable travel window of 60 to 160 mm. The adjuster acts as a stop to set the end position and does not lock or hold the load without continuous air pressure.
