About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X325-100
The AirTAC SAIJ200X325-100 is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty applications requiring precise end-position tuning. A rear-mounted stroke adjuster allows you to dial back the 325 mm nominal travel by up to 100 mm, creating a usable 225-325 mm stroke window. This eliminates the need to swap cylinders or bolt on external stops during product changeovers.
The extruded aluminum barrel features sensor grooves on both sides for CMSE or DMSE switches, though this specific configuration omits the magnet. The carbon steel piston rod utilizes an M36x2 thread and a G3/4 port. Because the stroke exceeds 300 mm, external guidance is recommended to manage side loads on the large 40 mm rod. The rear adjuster acts purely as a mechanical stop to set the retract end-position and is not a locking device.

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 SAIJ200X325-100 Is Used
Heavy Press Changeover
Adjusts the retract stop by up to 100 mm to accommodate varying material thicknesses in large-scale metal forming and pressing operations without hardware swaps.
Pallet Positioning
Fine-tunes the end-stop position on large conveyor sorting lines to handle different pallet depths dynamically during production runs.
Large Assembly Setup
Dials in the exact 225 to 325 mm travel window required for mating heavy machinery components during initial machine commissioning.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X325-100 the Right Cylinder?
Selecting this 200 mm bore model provides massive output force for high-inertia loads. If 15708 N at 0.5 MPa is excessive, stepping down to a 160 mm bore yields 10053 N, whereas staying with the 200 mm bore maximizes thrust up to 3204 kgf at 1.0 MPa. The 100 mm adjustment range is ideal for machinery requiring frequent format size changes, offering a wide 225-325 mm travel window without physically replacing the actuator. Unlike a fixed-stroke SAI cylinder, the SAIJ variant fine-tunes the retract position at commissioning.
For ISO 15552 interchangeability, match the 200x325-100 dimensions, G3/4 PT tapered ports, and the standard carbon steel rod. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets. Note that the rear adjuster and the variable air cushions only decelerate the load; they do not hold position without live air. For true load-holding without continuous pressure, consider the SAIL or BSAI series.
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 SAIJ200X325-100 FAQ
At the maximum 1.0 MPa pressure, it delivers 3204 kgf.
The rear adjuster screw lets you shorten the 325 mm nominal stroke by up to 100 mm, creating a 225-325 mm usable travel window. It acts as a mechanical end-stop and is not a lock, meaning the cylinder requires live air to hold its position.
