About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X75-50
The AirTAC SAIJ200X75-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust for heavy-duty tasks. By utilizing the 50mm adjustment range, you can dial the effective travel back from its 75mm nominal length, creating a precise 25-75mm usable window to perfect machinery end positions during commissioning.
This model features a robust 40mm carbon steel rod and a G3/4 PT tapered port to handle high airflow demands. It uses a 50mm variable air cushion at both ends to manage kinetic energy, though the rear stopper only sets the travel end and does not hold the load without live air. For position holding without pneumatic pressure, an external rod lock or a related SAIL cylinder 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 SAIJ200X75-50 Is Used
Heavy Press Tuning
Dial in the exact 25-75mm end-position for high-tonnage pressing operations without swapping out heavy tooling or cylinders.
Product Changeovers
Quickly adjust the stroke length on automated lines to accommodate different large-scale product sizes during format changes.
Assembly Station Setup
Fine-tune the retraction point during initial machine commissioning to prevent over-travel and ensure precise component mating.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X75-50 the Right Cylinder?
The adjustable stroke is chosen over a fixed SAI cylinder when you need variable end-stops for product-size changeovers on a line, allowing you to fine-tune the 25-75mm travel window without adding external stops. To match this cylinder for an ISO 15552 replacement, confirm the 75mm stroke, 50mm adjustment, G3/4 PT port, and your required mounting style.
Because the stroke is 75mm, the side-load risk is minimal, but the massive 40mm rod and M36x2 thread provide excellent rigidity against any inherent mounting offset. Note that SAIJ supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. If you need position feedback, you must specify the -S magnet option to utilize CMSE reed or DMSE electronic sensors in the dual-side sensor grooves.
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 SAIJ200X75-50 FAQ
The rear adjuster acts as a mechanical stop that allows you to shorten the 75mm nominal stroke by up to 50mm, providing a usable travel window of 25-75mm. This stopper only sets the end position and does not lock the load without continuous air pressure.
