Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-50S
The AirTAC Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-50S 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 SAIJ200AX220-50S
The AirTAC SAIJ200X220-50-S is a double-acting ISO 15552 profile cylinder with a 200 mm bore and a 220 mm stroke. An integrated rear adjusting screw provides a 50 mm trim range, creating a usable travel window of 170-220 mm for precise end-position tuning during commissioning. It delivers robust thrust, pushing 15708N and pulling 15080N at 0.5 MPa, scaling to a maximum of 3204 kgf at 1.0 MPa.
This variant includes a -S magnet for CMSE reed and DMSE electronic sensors, fitting into the extruded aluminum barrel's dual-side sensor grooves. The piston rod uses SUS420J2 stainless steel (code A) for corrosion resistance, and fluid supply connects via PT tapered G3/4 ports. The rear adjuster acts purely as a travel stop for deceleration, so it will not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-50S Is Used
Heavy Press Tuning
Dial in the exact 170-220 mm travel window during heavy press setup to accommodate material thickness variations without changing tooling.
Product Changeover
Quickly adjust the rear stopper by up to 50 mm on automated lines to handle different product sizes, reducing machine downtime.
End-Position Calibration
Fine-tune the retract end position at commissioning using the rear screw, avoiding the need for external stop blocks on the machine frame.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX220-50S the Right Cylinder?
Selecting this 200 mm bore over a smaller 160 mm unit increases thrust from 10053N to 15708N at 0.5 MPa, making it ideal for heavy pressing and forming. The 50 mm adjustment range is chosen when you need variable end-stops for product changeovers without physically swapping the cylinder. For load-holding without continuous air pressure, this cylinder is insufficient; an AirTAC SAIL (air-released lock) or BSAI (clamp-lock) is required instead.
As a dimensionally interchangeable ISO 15552 profile cylinder, it replaces units of matching bore, 220 mm stroke, 50 mm adjustment, G3/4 PT ports, and SUS420J2 rod. It supports a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the stroke is 220 mm, the 40 mm rod and M36x2 thread handle high side loads, though an external guide is recommended for unsupported 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 SAIJ200AX220-50S 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 rated pressure of 1.0 MPa, it delivers up to 3204 kgf.
The rear adjuster screw allows you to shorten the 220 mm nominal stroke by up to 50 mm, providing a usable travel window of 170-220 mm. It functions as a mechanical stop to tune the end position and does not lock the load without live air pressure.
