Airtac SAIJ80 Adjustable Cylinder SAIJ80X200-30S
The AirTAC Airtac SAIJ80 Adjustable Cylinder SAIJ80X200-30S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 200mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X200-30S
The AirTAC SAIJ80X200-30-S is a double-acting, single-rod ISO 15552 profile cylinder featuring a built-in rear stroke adjuster. It delivers 2513N of push force at 0.5MPa and provides a usable travel window of 170 to 200mm, letting you trim up to 30mm of stroke during commissioning without adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and this -S variant includes a magnet ready for CMSE reed or DMSE electronic switches.
Equipped with a 25mm carbon steel rod and M20x1.5 threading, it handles substantial side loads, while the PT tapered ports (G3/8) ensure leak-free pneumatic connections. The rear adjuster acts purely as a mechanical stop to fine-tune the end position, meaning it will not hold the load without live air pressure. For true load-holding without continuous air, consider the SAIL or BSAI series.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X200-30S Is Used
Machine Changeover
Dial in the 170-200mm travel window on the fly to accommodate different product sizes on the same line without physically replacing the cylinder.
End-Stop Calibration
Fine-tune the retract end position during commissioning using the rear screw, ensuring precise mechanical alignment without external spacers.
Assembly Pressing
Leverage the 2513N push force at 0.5MPa for pressing operations, using the 30mm adjustment to set exact pressing depth limits.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X200-30S the Right Cylinder?
Choose this 80mm bore adjustable-stroke model when your application requires exact end-position tuning during setup or product changeover, avoiding the need to swap out a fixed-stroke SAI cylinder. If your force requirements are lower, stepping down to a 63mm bore yields 1559N of push force at 0.5MPa; stepping up to a 100mm bore provides 3927N. Since this unit features a 200mm stroke, it is safely below the side-load threshold, but longer unsupported strokes should always use an external guide.
This cylinder is dimensionally interchangeable with ISO 15552 cylinders. To match this exact configuration, specify an 80mm bore, 200mm nominal stroke, 30mm adjustment range, PT port threads, and the -S magnet option. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ80X200-30S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 30mm, providing a usable travel window of 170 to 200mm. It only sets the end position and does not lock or hold the load without continuous air pressure.
At 0.5MPa it provides 2513N of push force and 2268N of pull force. The operational speed range is 30-800mm/s, and it uses G3/8 PT tapered ports.
