Airtac SAIJ200 Adjustable Cylinder SAIJ200X80-30
The AirTAC SAIJ200 Adjustable Cylinder SAIJ200X80-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 80mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X80-30
The AirTAC SAIJ200X80-30 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring precise end-position tuning. Equipped with a 40mm carbon steel rod and PT tapered G3/4 ports, it delivers exceptional thrust, pushing with 15708N and pulling with 15080N at 0.5 MPa. The integrated rear adjusting screw allows you to shorten the effective stroke, providing a usable travel window of 50-80mm to perfectly dial in end stops without swapping hardware.
Unlike a fixed-stroke SAI cylinder, this model lets you fine-tune the retract position directly at commissioning or during product-size changeovers. The rear stopper works alongside the 50mm variable air cushions at both ends to decelerate the massive 3204 kgf maximum load, though it acts purely as a travel stop and not a lock. The extruded aluminum barrel features sensor grooves on both sides, ready for DMSE solid-state or CMSE reed switches if a magnet is specified later.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X80-30 Is Used
Heavy Press Tuning
Dial in the exact 50-80mm travel window during heavy press commissioning to accommodate material thickness variations without machining custom spacers.
End-Stop Calibration
Use the rear screw to precisely set the end-of-stroke position for massive actuators, ensuring perfect alignment without external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X80-30 the Right Cylinder?
Choose this 200mm bore cylinder when your application demands extreme force alongside variable end-stops. The SAIJ200X80-30 is selected over a fixed SAI when a machine processes multiple part sizes, allowing operators to dial back the stroke by up to 30mm on the fly. Because the 80mm stroke is short, side-loading is minimal, but the robust 40mm rod and M36x2 thread handle high off-center stresses well.
For ISO 15552 dimensionally interchangeable replacements, match the 200mm bore, 80mm stroke, 30mm adjustment, PT G3/4 ports, and standard carbon steel rod. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR. Remember that the rear adjuster and air cushions do not hold the load without live air; for true fail-safe load holding, select an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder instead.

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 SAIJ200 Adjustable Cylinder SAIJ200X80-30 FAQ
At its maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop that allows you to shorten the 80mm nominal stroke by up to 30mm, creating a usable travel window of 50-80mm. It fine-tunes the end position but does not lock the load without continuous air pressure.
