About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X290-100
The AirTAC SAIJ80X290-100 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It provides a nominal 290 mm stroke with a 100 mm adjustment range, creating a usable travel window between 190 mm and 290 mm. This built-in stopper allows you to dial in the exact end position at commissioning without adding external physical stops or swapping the cylinder.
Delivering 2513 N of push force and 2268 N of pull force at 0.5 MPa, this 80 mm bore unit is built for robust actuation. It features a 25 mm carbon steel rod with an M20x1.5 thread, providing high rigidity against side loads. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed and DMSE electronic switches, though this specific SKU is configured without a magnet. The rear adjuster acts solely as a travel stop and does not lock the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X290-100 Is Used
Variable End-Stop Tuning
Dial in the exact retract distance between 190 and 290 mm during machine commissioning to perfect the seating force without replacing the entire cylinder.
Product Changeover Lines
Rapidly adjust the travel end by up to 100 mm to accommodate different package sizes or material lengths on a shared conveyor setup.
Heavy Clamping Setups
Leverage the 2513 N push force at 0.5 MPa to secure heavy workpieces, using the rear screw to fine-tune the clamping depth precisely.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X290-100 the Right Cylinder?
Choose this 80 mm bore adjustable cylinder when your application requires heavy thrust that exceeds the 1374 N push force of a 50 mm bore, but you want to avoid the larger footprint and 3518 N force of a 125 mm unit. The 100 mm adjustment range is ideal for production lines handling frequent product-size changeovers, allowing operators to reposition the end-of-stroke limit rapidly instead of machining new hard stops.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 290 mm stroke, PT tapered port threads, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 290 mm stroke approaches the mid-range of standard travel, ensure your payload is guided externally; while the 25 mm rod handles high stress, long unsupported strokes still require a separate guide rail to prevent binding. For load-holding without live air, select a SAIL or BSAI series cylinder instead, as the SAIJ rear adjuster is a stop, not a brake.

- ✓ 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 SAIJ80X290-100 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 pressure of 1.0 MPa, it can deliver up to 513 kgf.
The rear adjuster screw lets you shorten the effective stroke from the nominal 290 mm down to 190 mm. This creates a 190-290 mm travel window for fine-tuning the end position at commissioning without changing the cylinder itself.
