About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X500-40S
The AirTAC SAIJ200X500-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 21991N at 0.7MPa and pulling 15080N, while the integrated -S magnet enables position feedback via CMSE reed or DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides for flexible switch mounting.
With a nominal 500mm stroke and a 40mm adjustment range, this SKU provides a usable travel window of 460-500mm. This built-in adjustability allows you to fine-tune the retract end-position during commissioning without swapping the cylinder or adding external stops. The 40mm carbon steel rod and M36x2 thread provide a robust interface, though long unsupported strokes like this still require an external guide to handle side loads.

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 SAIJ200X500-40S Is Used
Heavy Press Tuning
Dial in the exact 460-500mm end-stop during machine setup to accommodate varying material thicknesses without changing the cylinder.
Product Changeover
Quickly adjust the retract position on a production line when switching to a different pallet or product size, saving commissioning time.
Large Mold Handling
Fine-tune the retraction distance for heavy mold positioning, ensuring precise alignment before the final clamp engages.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X500-40S the Right Cylinder?
Choose this 200mm bore when your application requires extreme force, pushing 28274N at 0.9MPa. If you need less thrust, stepping down to a 160mm bore yields 18095N at 0.9MPa, while keeping the same 500mm stroke and 40mm adjuster. The rear adjuster on this SAIJ acts purely as a mechanical stop to set the travel end; it does not hold the load without live air pressure. For true load-holding without continuous air, consider the SAIL or BSAI series.
This model is dimensionally interchangeable per ISO 15552 and uses a PT tapered port thread. It supports the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the stroke is 500mm, an external guide is strongly recommended to prevent excessive side-load wear on the rod seals.
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 SAIJ200X500-40S FAQ
At 0.7 MPa, it pushes 21991N and pulls 15080N.
The rear adjuster screw lets you shorten the effective stroke by up to 40mm, providing a usable travel window of 460-500mm. It functions as a travel stop for end-position tuning, not as a lock, and does not hold the load without live air pressure.
