About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX220-20S
The AirTAC SAIJ200X220-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, generating 15708N push force and 15080N pull force at 0.5 MPa. The integrated -20 adjustment screw allows you to trim the effective travel back by up to 20 mm, creating a precise 200-220 mm usable stroke window without needing external stops.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and ships with a magnet for CMSE and DMSE sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the PT G3/4 port handles high airflow. Remember that the rear adjuster functions strictly as a travel stop, not a lock; it cannot hold a load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX220-20S Is Used
Heavy Press Tuning
Dial in the exact 200-220 mm end position during heavy press commissioning to accommodate material thickness variations without changing tooling.
Product Changeover
Quickly adjust the stroke by up to 20 mm on a packaging line when switching to a different pallet size, saving setup time.
Corrosive Force Application
Leverage the 15708N force and SUS304 stainless steel rod for high-impact positioning tasks in washdown or mildly corrosive environments.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX220-20S the Right Cylinder?
Choose this 200 mm bore cylinder when an application requires extreme force that smaller bores cannot provide, such as stepping up from a 160 mm bore that yields 10053N push force at 0.5 MPa. The adjustable stroke is ideal for fine-tuning end positions during machine setup or product changeovers, preventing the need to swap out a fixed-stroke SAI cylinder. For load-holding without continuous air pressure, you must integrate an external rod lock or select a SAIL or BSAI model.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 220 mm stroke, 20 mm adjustment range, PT G3/4 port, and the -S magnet requirement. Because the 220 mm stroke is relatively short for this large bore, side-loading is less severe than with long strokes, but the heavy 40 mm rod and M36x2 thread still require proper external guiding to prevent binding.
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 SAIJ200BX220-20S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708N of push force and 15080N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw lets you shorten the 220 mm nominal stroke by up to 20 mm, providing a usable travel window of 200 to 220 mm. This stopper sets the end position but does not lock the load without live air pressure.
