About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X500-75S
It features a 500mm nominal stroke paired with a rear mechanical adjuster that creates a precise 425-500mm usable travel window. This built-in stopper allows you to fine-tune the retract end position during commissioning without swapping out the entire unit.
Equipped with a PT tapered port and an integrated magnet (-S), this model supports AirTAC CMSE reed and DMSE electronic solid-state sensors housed within the dual-side extruded aluminum barrel grooves. The robust 40mm carbon steel rod and M36x2 thread handle significant loads, while the adjustable end-stop acts purely as a travel deceleration point, not a lock.

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 SAIJ200X500-75S Is Used
Heavy Press Tuning
Dial in the exact 425-500mm end position for large metal forming or press operations during initial setup without external stop blocks.
Product Changeover
Quickly adjust the retract depth by up to 75mm on automated lines handling varying large-format product sizes.
Long-Stroke Guiding
Utilize the 40mm carbon steel rod for heavy thrust tasks, paired with an external guide to manage side loads on the 500mm stroke.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X500-75S the Right Cylinder?
The 75mm adjustment range is ideal for dialing in long-stroke machinery without adding external stops. For any 500mm stroke, an external guide is recommended to manage side-load stresses on the 40mm rod.
This SAIJ configuration uses a PT port thread and includes a magnet for position sensing. It supports the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Remember that the rear adjuster only sets the travel end; to hold a load securely without live air pressure, consider an AirTAC SAIL or BSAI locking cylinder.
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 SAIJ200X500-75S FAQ
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke from its 500mm nominal length down to 425mm. This creates a 425-500mm travel window for fine-tuning the end position at commissioning, but it does not lock the load without continuous air pressure.
