About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-40S
The AirTAC SAIJ200X750-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 15708N at 0.5 MPa. It features a SUS420J2 stainless steel rod and a PT tapered port. The built-in magnet supports CMSE reed and DMSE electronic sensors for precise position detection.
With a 750mm nominal stroke and a 40mm adjustment code, this model provides a usable travel window of 710-750mm. This allows you to fine-tune the retract end position at commissioning without swapping the cylinder. The extruded aluminum barrel includes sensor grooves on both sides, and the robust 40mm rod with M36x2 thread handles high side loads, though a 750mm stroke still requires an external guide.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-40S Is Used
Heavy Stamping Setup
Fine-tune the 710-750mm travel window during heavy stamping commissioning to achieve exact bottom-dead-center positioning without external shims.
Large Product Changeover
Quickly adjust the retract end-stop on a production line when switching between large product sizes, leveraging 15708N of thrust for demanding tasks.
Guided Heavy Lifting
Move massive payloads along a 750mm stroke, relying on the 40mm SUS420J2 rod for rigidity while an external guide manages side-load forces.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX750-40S the Right Cylinder?
Choose this 200mm bore cylinder when you need extreme force, stepping up from a 160mm bore that provides 10053N push force at 0.5 MPa. The adjustable stroke is ideal for product changeovers on heavy machinery, letting you dial in the end-stop precisely without adding external stops. For a fixed end position, a standard SAI cylinder suffices.
This SAIJ200X750-40-S uses PT ports and supports the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Remember that the rear adjuster acts only as a travel stop and the air cushions handle deceleration; neither holds the load without live air. For load-holding without pneumatic pressure, consider an external rod lock or the AirTAC SAIL lock cylinder. Operating speed is 30-500mm/s.
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 SAIJ200AX750-40S FAQ
At 0.5 MPa, this 200mm bore cylinder provides a push force of 15708N and a pull force of 15080N. At 0.7 MPa, the push force increases to 21991N.
The rear adjuster allows you to trim the effective stroke by up to 40mm, creating a usable travel window of 710-750mm. It acts as a mechanical stop to fine-tune the end position and does not lock the load without live air.
