About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX210-20S
The AirTAC SAIJ200X210-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end position during commissioning without adding external stops. It provides a usable travel window of 190-210mm, trimming the nominal 210mm stroke by up to 20mm. Belonging to the 200mm bore class, it supplies massive thrust up to 15708N at 0.5MPa and 21991N at 0.7MPa.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for use with CMSE reed and DMSE electronic sensors. It utilizes a PT tapered G3/4 port and incorporates variable air cushions at both ends. The extruded aluminum barrel design includes sensor grooves on both sides, and the mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX210-20S Is Used
Heavy Pressing Operations
Apply up to 21991N of force at 0.7MPa for heavy assembly presses, using the 20mm adjuster to set the exact bottoming position without mechanical shims.
Product Changeover Systems
Quickly adapt the 190-210mm travel window on automated lines when product sizes change, ensuring precise end-stops without replacing the entire cylinder.
Corrosive Environment Automation
Leverage the SUS304 stainless steel rod in washdown or corrosive manufacturing settings while maintaining ISO 15552 mounting interchangeability.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX210-20S the Right Cylinder?
Choose this 200mm bore when an application requires extreme push force, stepping up significantly from the 160mm bore which offers 10053N at 0.5MPa. The adjustable stroke is ideal for product changeovers on a line, letting you dial in the exact 190-210mm travel without swapping the cylinder. If the machine loses air, this cylinder will not hold its load; the rear adjuster is strictly a travel stop, not a lock. For true fail-safe load-holding without live pressure, consider the SAIL or BSAI series. Because the 210mm stroke exceeds 300mm? No, but even at 210mm, the heavy mass moved by a 40mm rod means an external guide is recommended to prevent side-load damage. To match this ISO 15552 cylinder, specify the 200mm bore, 210mm stroke, 20mm adjustment, PT G3/4 port, and the -S magnet.

- ✓ 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 SAIJ200BX210-20S FAQ
At 0.5MPa it provides 15708N of push force and 15080N of pull force. At 0.7MPa, the push force increases to 21991N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the 210mm nominal stroke down to 190mm, creating a 190-210mm adjustable window for fine-tuning at commissioning.
