About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X30-30S
The AirTAC SAIJ200X30-30-S is a double-acting, double-rod ISO 15552 profile cylinder engineered for high-force applications requiring exact end-position control. It features a rear adjusting screw that allows you to trim the effective stroke within a 0-30 mm usable travel window, providing fine-tuning at commissioning without the need to swap out the unit.
This variant includes a standard carbon steel rod and a -S magnet for compatibility with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides, and fluid supply is routed through a PT G3/4 port. It utilizes variable air cushions at both ends to decelerate the load smoothly.

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 SAIJ200X30-30S Is Used
Short-Stroke Pressing
Ideal for high-force pressing operations where the 0-30 mm travel window allows operators to dial in the exact end-position for different material thicknesses without changing tooling.
Machine Changeover
Perfect for automated lines that process multiple product sizes, allowing the rear stopper to be quickly adjusted during changeovers to set precise clamping depths.
Heavy Ejector Setup
Provides massive ejection force in compact spaces, using the fine stroke adjustment to compensate for mechanical wear over time without repositioning the cylinder.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X30-30S the Right Cylinder?
Selecting this 200 mm bore model is appropriate when your application demands massive thrust (up to 3204 kgf at 1.0 MPa) within a very short 30 mm nominal travel distance. The adjustable 0-30 mm window on this SKU is ideal for dialing in exact end-stops during machine setup or product changeover, a distinct advantage over a fixed-stroke SAI cylinder.
Because the nominal stroke is under 300 mm, external side-load guides are less critical here than on long-stroke setups, though the robust 40 mm rod and M36x2 thread handle substantial loads. Remember that the rear adjuster and air cushions act only as travel stops and deceleration devices; they do not hold the load without live air pressure. For true load-holding, consider an AirTAC SAIL or BSAI cylinder. This SAIJ model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and is dimensionally interchangeable per ISO 15552.
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 SAIJ200X30-30S FAQ
At the maximum operating pressure of 1.0 MPa, it delivers a peak push force of 3204 kgf.
The rear adjuster screw allows you to shorten the effective travel by up to 30 mm from the nominal 30 mm stroke, creating a 0-30 mm adjustable window. This stopper only sets the end position and decelerates the load; it does not lock the load without live air pressure.
