About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X475-40
It features an extruded aluminum barrel with sensor grooves on both sides, designed to host CMSE reed or DMSE electronic sensors if a magnet is specified later. This 200mm bore unit utilizes a robust 40mm carbon steel rod and M36x2 rod thread to withstand high side-load stresses.
Equipped with a 40mm rear stroke adjuster, this model allows you to fine-tune the effective travel window anywhere between 435 and 475mm during commissioning. The external stopper screw lets you dial in the exact retract position for product changeovers without swapping out the entire cylinder or fabricating external stops. The rear adjuster acts purely as a travel stop and deceleration point, meaning it will not hold a load safely without continuous live air pressure.

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 SAIJ200X475-40 Is Used
Heavy Press Tuning
Dial in the exact 435-475mm retract position on a high-tonnage press to accommodate varying material thicknesses without changing machine tooling.
Pallet Changeover Stop
Adjust the end-stop on the fly for different pallet depths, ensuring precise positioning of heavy loads on a conveyor line.
Large Assembly Jig
Fine-tune the clamping distance on large-scale automotive or industrial assembly jigs during initial setup and product revisions.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X475-40 the Right Cylinder?
The SAIJ200X475-40 is selected over a fixed-stroke SAI variant when machinery demands variable end-stops for different product sizes running on the same line.
Because the 475mm stroke is substantial, the heavy 40mm rod and M36x2 thread still require an external guide to prevent sagging and premature seal wear over long unsupported distances. This cylinder uses a PT tapered G3/4 port, accepts the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), and lacks a standard magnet. For operations requiring fail-safe load holding without live air, consider the AirTAC SAIL pneumatic lock or BSAI clamp-lock series instead of relying on the adjuster stop.
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 SAIJ200X475-40 FAQ
It can deliver a maximum force of 3204 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the nominal 475mm stroke by up to 40mm, creating a usable travel window between 435mm and 475mm. This allows precise end-position tuning during commissioning without adding external stops.
