About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X800-30
The AirTAC SAIJ200X800-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster that permits you to dial back the nominal 800 mm travel by up to 30 mm, yielding a 770-800 mm usable end-position window. Built with a robust 40 mm carbon steel rod and M36x2 thread, it handles heavy loads up to 15080 N of pull force at 0.5 MPa. The extruded aluminum barrel incorporates sensor grooves on both sides, and because this unit lacks a -S magnet, you would mount external proximity switches rather than embedded CMSE or DMSE sensors if detection is required.
This model utilizes PT tapered port threads (G3/4) and relies on variable air cushions at both ends to decelerate the massive 3204 kgf maximum kinetic load. The rear stopper mechanism strictly governs the travel endpoint and deceleration; it is not a mechanical lock, so the cylinder cannot hold a suspended load without live air pressure. For fail-safe load holding, an external rod lock or a related AirTAC series like SAIL or BSAI is required.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X800-30 Is Used
Heavy Press Fine-Tuning
Dial in the exact 770-800 mm bottom-dead-center of a large stamping or forming press during setup, allowing 30 mm of adjustment to compensate for tooling height variations without changing the cylinder.
Variable Stroke Ejection
Adjust the rear stopper on a heavy-duty ejection station to tune the retract distance for different product sizes, ensuring parts clear the machine safely during production changeovers.
Long-Travel Positioning
Set precise end-of-stroke limits on a long 800 mm travel conveyor diverter or heavy lifting station, using the 30 mm adjustment window to perfect the transfer position at commissioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X800-30 the Right Cylinder?
Choose this 200 mm bore unit when an application demands immense thrust that a 160 mm bore cannot provide; stepping down to the 160 mm neighbor yields 9425 N of pull at 0.5 MPa, which may be insufficient for heavy forming or pressing. The adjustable stroke feature is selected over a fixed-stroke SAI cylinder when you need in-field commissioning fine-tuning or product changeover flexibility without swapping out the actuator or adding external stops.
Because the stroke extends to 800 mm, the long unsupported rod is highly susceptible to side-loading and sagging; an external guide rail must be used to prevent premature seal wear and binding. When specifying a replacement, ensure the ISO 15552 mounting interface matches the reduced SAIJ accessory set: Basic, FA, LB, TC, FTC, TCM1, or TCM2. This SKU omits the FB, CA, CB, and CR mounts found on some standard actuators.

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 SAIJ200X800-30 FAQ
At its maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster acts as a mechanical stop that lets you trim the effective travel back by up to 30 mm, creating a 770-800 mm usable stroke window. It only sets the end position and deceleration; it does not lock the load without continuous air pressure.
