About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX80-20S
The AirTAC SAIJ200X80-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 15708N at 0.5 MPa. Its 80mm nominal stroke can be dialed back by up to 20mm, creating a precise 60-80mm usable travel window for fine-tuning end positions during commissioning. The extruded aluminum barrel integrates sensor grooves on both sides, and the -S magnet enables position detection with CMSE reed or DMSE electronic switches.
This heavy-duty unit features a 40mm SUS304 stainless steel rod (code B) for superior corrosion resistance, paired with a PT tapered port and a 50mm air cushion at both ends to manage high kinetic energy. The rear adjuster acts purely as a mechanical stop to set the retraction point without needing external stops, though it does not lock the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX80-20S Is Used
Heavy Press Tuning
Dial in the exact 60-80mm end position for high-tonnage pressing operations without adding external mechanical stops.
Product Changeover
Quickly adjust the retraction point on a packaging line to accommodate different product sizes using the 20mm trim window.
Corrosive Assembly
Leverage the 15708N push force and SUS304 stainless steel rod for heavy assembly tasks in washdown or corrosive environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX80-20S the Right Cylinder?
Selecting this 200mm bore cylinder is appropriate when an application requires extreme force, as stepping down to a 160mm bore yields 10053N of push force at 0.5 MPa. The adjustable 60-80mm travel window is ideal for product-size changeovers on a line, allowing operators to dial in the exact end-stop without swapping cylinders. For load-holding without continuous air pressure, a plain SAIJ is insufficient since the rear adjuster is a stop, not a lock; consider an AirTAC SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 200mm bore, 80mm stroke, 20mm adjustment, PT ports, and SUS304 rod. Mounting options include the SAIJ subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 80mm stroke is relatively short for this bore, side-load stress is minimized, but an external guide remains recommended for heavy loads.
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 SAIJ200 Adjustable Cylinder SAIJ200BX80-20S FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At the maximum 1.0 MPa pressure, it achieves 3204 kgf.
The rear adjuster screw allows you to shorten the 80mm nominal stroke by up to 20mm, providing a usable travel window of 60-80mm. It functions as a mechanical stop to fine-tune the end position and does not lock the load without live air.
