About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X210-30
The AirTAC SAIJ80X210-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits you to dial back the travel by up to 30 mm. This yields a usable end-position window of 180 to 210 mm, allowing precise fine-tuning at commissioning without swapping the barrel or adding external stops. It delivers a robust 2513 N push force at 0.5 MPa, making it well-suited for heavy manipulation tasks.
Equipped with a 25 mm carbon steel rod and an M20x1.5 thread, this unit handles substantial side loads while operating at speeds from 30 to 800 mm/s. The extruded aluminum barrel incorporates sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. Mounting options include the reduced SAIJ set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR variants.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X210-30 Is Used
Machine Setup & Changeover
Fine-tune the 180 to 210 mm travel window during product changeovers to accommodate different part sizes without physically swapping cylinders on the line.
Variable End-Stop Positioning
Dial in the exact retraction point for pusher arms on a conveyor, using the 30 mm rear adjustment screw to compensate for mechanical wear over time.
Heavy Part Ejection
Leverage the 2513 N push force at 0.5 MPa to eject heavy machined components from a fixture, adjusting the stroke length to ensure safe clearance.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X210-30 the Right Cylinder?
Choose this 80 mm bore variant when your application requires the 2513 N push thrust at 0.5 MPa, stepping up from the 50 mm bore which provides 982 N, or down from the 100 mm bore delivering 3927 N. An adjustable stroke is highly advantageous over a fixed SAI cylinder when you need variable end-stops for product changeovers on a shared line. The rear adjuster acts purely as a travel stop and does not hold the load without live air; for true fail-safe load holding, consider the SAIL or BSAI series. As an ISO 15552 interchangeable unit, ensure your setup matches the PT G3/8 port and 210 mm stroke. For a 210 mm stroke, ensure external guides are used to support the rod against lateral forces.

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 SAIJ80X210-30 FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 30 mm, creating a usable travel window between 180 and 210 mm. This stopper only sets the end position and decelerates the piston; it does not lock or hold the load without continuous air pressure.
At 0.5 MPa operating pressure, this 80 mm bore cylinder generates 2513 N of push force and 2268 N of pull force. It can deliver up to 4523 N of push force at its maximum operating pressure of 0.9 MPa.
