About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X240-75
The AirTAC SAIJ200X240-75 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 15708 N at 0.5 MPa, making it suited for heavy-duty industrial tasks. By turning the rear screw, you can trim the effective travel anywhere within a 165-240 mm window, providing exact end-position tuning without swapping out the entire unit.
This adjustable-stroke design saves significant setup time during product changeovers, eliminating the need to bolt on external stops. The extruded aluminum barrel features sensor grooves on both sides for flexible switch mounting. It uses a robust 40 mm carbon steel rod with an M36x2 thread, and its variable air cushions at both ends manage deceleration smoothly across its 30-500 mm/s speed range.

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 SAIJ200X240-75 Is Used
Heavy Press Tuning
Fine-tune the 165-240 mm end-stop during heavy press commissioning to achieve precise material forming without adding external mechanical stops.
Product Changeovers
Rapidly adjust the rear stroke screw on a packaging line to accommodate different box sizes, cutting machine downtime significantly.
Variable End Positioning
Dial in the exact retraction point for heavy material handling fixtures, ensuring parts seat properly against rigid stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X240-75 the Right Cylinder?
The SAIJ200X240-75 is chosen over a fixed-stroke SAI when a machine handles multiple product sizes, allowing operators to dial in the 165-240 mm travel window on the fly. For an exact ISO 15552 replacement match, verify the 240 mm stroke, 75 mm adjustment range, PT port thread, and mounting style.
Because the 240 mm stroke is substantial, ensure adequate external guiding to protect the 40 mm rod from excessive side-loading. Remember that the rear adjuster acts only as a travel stop, not a locking device; the cylinder cannot hold a load without live air pressure. For load-holding requirements, consider an AirTAC SAIL or BSAI cylinder. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and 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 SAIJ200X240-75 FAQ
At a maximum 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 240 mm nominal stroke by up to 75 mm. This creates a usable travel window of 165-240 mm, enabling precise end-position tuning without replacing the cylinder.
