About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-100
The AirTAC SAIJ80X130-100 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 130 mm stroke that can be dialed back by up to 100 mm, yielding a highly versatile 30 to 130 mm usable travel window for exact end-position tuning during commissioning. Delivering a push force of 2513 N at 0.5 MPa, it handles substantial pneumatic workloads.
This unit features a 25 mm carbon steel piston rod with an M20x1.5 thread, offering robust resistance to side loading. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-100 Is Used
Product Changeover Lines
Dial in the exact 30 to 130 mm travel needed for different package sizes on a packaging line without physically replacing the cylinder.
Machine Setup & Prototyping
Fine-tune the retract end-position during initial commissioning to dial out mechanical clearances and achieve precise stopping locations.
Variable End-Stop Forming
Adjust the effective stroke on the fly to accommodate varying material thicknesses in pressing or forming applications.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X130-100 the Right Cylinder?
Choose this 80 mm bore when a project demands high thrust (2513 N at 0.5 MPa) alongside extreme stroke flexibility. The massive 100 mm adjustment range is ideal for prototyping or lines running multiple product sizes, allowing you to shift the end-stop without swapping cylinders. For lighter duty, a 63 mm bore offers 1559 N; for heavier loads, a 100 mm bore provides 3927 N.
When replacing an ISO 15552 cylinder, match the 130 mm nominal stroke, 100 mm adjustment, G3/8 PT ports, and the chosen mounting accessory. Because the stroke is 130 mm, ensure proper guidance for long unsupported rods to prevent side-load wear. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, select an SAIL or BSAI 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 SAIJ80X130-100 FAQ
At a 0.5 MPa operating pressure, this 80 mm bore cylinder generates a push force of 2513 N and a pull force of 2268 N. At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw lets you shorten the 130 mm nominal stroke by up to 100 mm, creating a 30 to 130 mm usable travel window. It acts as a mechanical stop and works with the built-in air cushions to decelerate the load, but it does not lock the position without continuous air pressure.
