About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX800-30
The AirTAC SAIJ200X800-30 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty tasks, delivering a substantial 15708N push force at 0.5MPa. It features a rear stroke adjuster that allows you to fine-tune the effective travel down to a 770-800mm window without swapping out the unit. This 200mm bore actuator uses a robust 40mm piston rod paired with a PT tapered G3/4 port to handle high flow demands.
Equipped with SUS420J2 stainless steel rod material (option A), it provides excellent corrosion resistance for demanding environments. The extruded aluminum barrel includes sensor grooves on both sides for straightforward position feedback, while the rear stopper screw enables precise end-position tuning during commissioning. The adjuster acts purely as a travel stop and does not lock the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX800-30 Is Used
Heavy Pressing Operations
Delivers up to 3204kgf at 1.0MPa for large-scale forming, stamping, and heavy industrial pressing tasks requiring immense output force.
Machine Changeover Setup
The 30mm rear adjuster allows operators to dial in the exact 770-800mm end-position during product size changes without replacing the cylinder.
Automated Assembly Lines
Ideal for moving heavy payloads along an 800mm travel path, utilizing the dual sensor grooves for precise positioning feedback.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX800-30 the Right Cylinder?
Selecting this 200mm bore model makes sense when your application requires extreme thrust, such as 15708N push or 15080N pull at 0.5MPa. If you need less force, stepping down to a 160mm bore yields 10053N push at 0.5MPa, but the SAIJ200X800-30 is necessary for heavy pressing or moving large masses. The adjustable stroke is chosen when you need variable end-stops for machine changeovers, avoiding the need to bolt on external stops or buy a fixed-stroke SAI cylinder.
Because this is an 800mm stroke, the 40mm rod requires an external guide to prevent excessive side-loading and premature seal wear. To replace an ISO 15552 cylinder, match the 200mm bore, 800mm stroke, 30mm adjustment, PT G3/4 port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interface. Note that the rear adjuster and air cushions only decelerate the travel end; for true load-holding without live air, consider an AirTAC SAIL or BSAI cylinder.

- ✓ 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 SAIJ200AX800-30 FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 30mm. This creates a usable travel window of 770-800mm, enabling fine-tuning of the end position during commissioning without changing the cylinder.
At a 0.5MPa operating pressure, the SAIJ200X800-30 provides a push force of 15708N and a pull force of 15080N. At the maximum 1.0MPa pressure, it can deliver up to 3204kgf of thrust.
