About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X200-10
The AirTAC SAIJ80X200-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a usable travel window of 190-200 mm, letting you fine-tune the retract end position by up to 10 mm during commissioning without adding external stops. It delivers a robust 2513 N push force at 0.5 MPa.
This model incorporates a 25 mm carbon steel rod and an M20x1.5 thread to handle high side-load stresses. It features variable air cushions at both ends to decelerate the motion smoothly. The extruded aluminum barrel includes sensor grooves on both sides, ready to accept CMSE reed or DMSE electronic sensors if a magnet is added later.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X200-10 Is Used
End-Position Tuning
Dial in the exact retract position within a 190-200 mm window during machine commissioning to perfect a pressing or clamping operation.
Product Changeover
Quickly adjust the end stop by up to 10 mm on a packaging line when switching to a slightly different product size, avoiding cylinder swaps.
Automated Assembly
Use the 2513 N push force to drive heavy actuators, relying on the built-in air cushions and the rear stopper to manage final positioning.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X200-10 the Right Cylinder?
Choose this 80 mm bore when your application requires the 2513 N push force at 0.5 MPa, stepping up from the 50 mm bore which provides 982 N. The 10 mm adjustment range is ideal for precision machine setup and product changeovers, offering a distinct advantage over a fixed-stroke SAI cylinder. The mounting hardware uses the reduced SAIJ set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. The pneumatic port is a tapered PT G3/8 thread.
Because this is a 200 mm stroke, the unsupported rod length is moderate, but you should still verify guiding for heavy lateral loads. Remember that the rear adjuster acts only as a travel stop, not a lock; the cylinder will not hold its load without live air pressure. For true load-holding, consider the SAIL or BSAI series. This unit is dimensionally interchangeable per ISO 15552.
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 SAIJ80X200-10 FAQ
At a 0.5 MPa operating pressure, this 80 mm bore cylinder provides a push force of 2513 N and a pull force of 2268 N. It can reach a maximum push force of 513 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 200 mm nominal stroke by up to 10 mm, providing an effective travel range of 190-200 mm. It is a travel stop, not a lock, meaning the cylinder requires live air to hold its position.
