About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X90-75
The AirTAC SAIJ200X90-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down from a 90 mm nominal stroke to a minimum of 15 mm. This creates a highly flexible 15-90 mm usable travel window, ideal for dialsing in exact end positions during machine setup without swapping hardware.
Equipped with a robust 40 mm carbon steel rod and an M36x2 thread, this cylinder handles heavy loads and greater side loads than smaller bores. The extruded aluminum barrel includes sensor grooves on both sides for mounting CMSE reed or DMSE electronic sensors if needed. It uses PT tapered G3/4 ports and features variable air cushions at both ends to decelerate the massive moving mass 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 SAIJ200X90-75 Is Used
Heavy Press Tuning
Dials in the exact 15-90 mm crushing or pressing depth on heavy assemblies during commissioning, allowing micro-adjustments to the end-stop without changing the cylinder.
Variable Product Forming
Accommodates multiple product heights on a single line by retracting the rear stopper up to 75 mm, instantly changing the effective stroke for different batch sizes.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X90-75 the Right Cylinder?
Select this 200 mm bore when your application requires maximum output force, as stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053 N. The 75 mm adjustment range is exceptionally large, making this specific SKU ideal for prototype tooling or production lines running varying product sizes, where the end-stop needs frequent reconfiguration instead of installing a fixed-stroke SAI cylinder. Remember that the rear adjuster is a travel stop, not a lock; it will not hold the load without live air pressure, so for fail-safe load holding you should look at the SAIL or BSAI series.
Because the 90 mm stroke is relatively short for this massive bore, the 40 mm rod is well-supported against side loads, though any heavy off-center tooling still requires an external guide. To replace an ISO 15552 cylinder of the same bore and stroke, match the 200 mm diameter, 90 mm base stroke, 75 mm adjustment requirement, G3/4 PT ports, and the standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).

- ✓ 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 SAIJ200X90-75 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjusting screw acts as an external stopper that trims the 90 mm nominal stroke back by up to 75 mm. This gives you a usable travel window of 15 to 90 mm, allowing precise end-position tuning at commissioning without needing external stops or a different cylinder.
