About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X100-100
The AirTAC SAIJ80X100-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 100 mm nominal stroke paired with a maximum adjustment range of 100 mm, yielding a highly versatile 0-100 mm usable travel window. This broad tuning capacity allows operators to set exact retract end-positions on the fly without swapping hardware. Delivering 2513 N of push force at 0.5 MPa, it handles substantial pneumatic workloads.
The extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting, though this specific SKU omits the magnet. It uses a robust 25 mm carbon steel rod with an M20x1.5 thread, providing excellent resistance to bending under high side loads. The rear adjuster functions purely as a mechanical stop to set the travel limit, meaning it will not hold a load in place without continuous live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X100-100 Is Used
Variable End-Stop Positioning
Ideal for assembly stations requiring frequent reconfiguration of the retract distance, utilizing the full 0-100 mm window to accommodate different part depths.
Machine Changeover
Speeds up product line changeovers by allowing technicians to dial in the exact stroke limit mechanically at the rear of the cylinder rather than reprogramming logic.
High-Force Clamping
Leverages the 2513 N push force at 0.5 MPa to secure heavy workpieces, while the adjustable stop ensures clamping pressure is reached at the precise mechanical endpoint.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X100-100 the Right Cylinder?
Selecting this 80 mm bore cylinder makes sense when an application demands significant force—such as the 2513 N push thrust at 0.5 MPa—combined with extreme setup flexibility. If a project requires less force, stepping down to a 63 mm bore yields 1559 N, while moving up to a 100 mm bore provides 3927 N. The 100 mm adjustment window is ideal for prototyping or production lines running multiple product sizes, allowing the end-stop to be dialed back precisely. For fixed-position tasks without variation, a standard SAI cylinder is a simpler choice.
Because this configuration utilizes a PT tapered port thread and a 25 mm rod, ensure your fittings and mechanical linkage match these exact specifications. The SAIJ mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR styles. If the machine design requires the load to be held statically without air pressure, this cylinder is not suitable; consider an AirTAC SAIL or BSAI locking cylinder instead.

- ✓ 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 SAIJ80X100-100 FAQ
At an operating pressure of 0.5 MPa, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster acts as a mechanical stop that can trim the effective travel back by up to 100 mm from the nominal 100 mm stroke, creating a 0-100 mm usable window. It sets the end position but does not lock the load without live air pressure.
