About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-50
The AirTAC SAIJ200X500-50 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a generous 15708N pull force at 0.5 MPa and a massive 28274N push force at 0.9 MPa, while allowing you to dial back the nominal 500mm stroke by up to 50mm. This creates a precise 450-500mm usable travel window, enabling exact end-position tuning at commissioning without swapping the cylinder or bolting on external stops.
Equipped with a SUS420J2 stainless steel rod (option A) and PT tapered port threads, this actuator is built for demanding environments. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic switches. Remember that the rear adjuster acts solely as a travel stop to decelerate the stroke end; it is not a lock, so the cylinder will not hold a load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-50 Is Used
Heavy Press Tuning
Dial in the exact 450-500mm travel window during heavy press commissioning to accommodate varying material thicknesses without changing tooling.
Product Changeover
Quickly adjust the rear stopper for different product sizes on a high-thrust assembly line, saving downtime compared to physically swapping actuators.
Large Fixture Setup
Fine-tune the end-position of heavy automated fixtures, using the 28274N output to securely shift massive loads into their final mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX500-50 the Right Cylinder?
Choose this 200mm bore size when your application requires extreme thrust that exceeds the 14074N push force of the neighbouring 160mm bore at 0.5 MPa. An adjustable-stroke cylinder is selected over a fixed SAI model when you need variable end-stops for machine setup or product changeover. To replace an ISO 15552 cylinder, match the 200mm bore, 500mm stroke, 50mm adjustment, PT G3/4 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is 500mm, the 40mm rod diameter will carry substantial side load, so an external guide is recommended to prevent rod bending.
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 SAIJ200AX500-50 FAQ
At 0.9 MPa operating pressure, this 200mm bore cylinder delivers a push force of 28274N and a pull force of 15080N. At 0.5 MPa, it provides 15708N push and 15080N pull.
The rear adjusting screw lets you shorten the effective travel by up to 50mm from the nominal 500mm stroke, providing a usable 450-500mm window. This stopper fine-tunes the retract end position but does not lock the load without live air pressure.
