Airtac SAIJ200 Adjustable Cylinder SAIJ200BX220-20
The AirTAC Airtac SAIJ200 Adjustable Cylinder SAIJ200BX220-20 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 220mm stroke, G3/4 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 SAIJ200 Adjustable Cylinder SAIJ200BX220-20
The AirTAC SAIJ200X220-20 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive 15708N push force at 0.5 MPa. It features a robust 40mm SUS304 stainless steel rod and PT tapered port threads. The integrated adjustment mechanism allows you to fine-tune the effective travel window down from the 220mm nominal stroke to a minimum of 200mm, providing a 20mm setup buffer without needing external stops.
Built with an extruded aluminum barrel housing sensor grooves on both sides, this unit omits heavy tie-rod construction while maintaining a true ISO 15552 mounting interface. It includes adjustable air cushions at both ends to decelerate high kinetic energy loads, operating smoothly at speeds of 30-500mm/s. The rear stopper screw sets the retract end position precisely during commissioning, though it functions strictly as a travel stop and not a load-holding lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX220-20 Is Used
Heavy Press Tuning
Dial in the exact 200-220mm retract distance during heavy press commissioning to accommodate material thickness variations without replacing the cylinder.
Product Changeover
Quickly adjust the end-stop position by up to 20mm on a packaging line when switching to a different product size, minimizing machine downtime.
Large Assembly Jigs
Position heavy structural components on an assembly jig, using the 40mm SUS304 rod to withstand harsh industrial environments while setting the exact retract limit.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX220-20 the Right Cylinder?
Selecting this 200mm bore model is appropriate when your application requires extreme thrust up to 15708N at 0.5 MPa (or 21991N at 0.7 MPa), and stepping down to a 160mm bore would leave you with only 10053N of push force. You should choose this adjustable-stroke SAIJ variant over a fixed-stroke SAI cylinder when your machine setup requires precise end-position tuning during commissioning or product changeovers. The 20mm adjustment window lets you dial in the exact retract distance without swapping out the physical cylinder.
Because the 220mm stroke exceeds 300mm? No, but at 220mm with a heavy 40mm rod, you must still evaluate side loads; long unsupported strokes require an external guide rail to prevent rod binding. This cylinder uses a PT port thread type and supports a specific mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Note that this plain SAIJ model does not hold position without live air pressure; for true fail-safe load holding, consider the SAIL or BSAI series instead.

- ✓ 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 SAIJ200BX220-20 FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At 0.7 MPa, the push force increases to 21991N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from the 220mm nominal length down to 200mm. This creates a 20mm adjustable travel window for fine-tuning the end position without adding external stops.
