About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X40-10
The AirTAC SAIJ200X40-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. The built-in adjuster allows you to trim the 40mm nominal stroke back by up to 10mm, creating a precise 30-40mm usable travel window for fine-tuning end positions during machine commissioning.
This massive 200mm bore unit features a 40mm carbon steel rod with an M36x2 thread, providing high rigidity against side loads. It includes variable air cushions at both ends to decelerate heavy masses smoothly. The rear screw acts solely as a travel stop and does not hold the load without live air pressure; for true load-holding, consider the SAIL or BSAI series.

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 SAIJ200X40-10 Is Used
Heavy Pressing Setup
Fine-tune the 30-40mm travel window during machine commissioning to achieve the exact pressing force required for heavy component insertion.
Product Changeover
Quickly adjust the rear stopper by up to 10mm to accommodate minor product size variations on the line without swapping out the entire cylinder.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X40-10 the Right Cylinder?
Selecting this 200mm bore cylinder makes sense when your application requires extreme thrust within a very short travel distance. The primary benefit of the SAIJ adjustable design over a fixed SAI cylinder is the ability to dial in the exact end-stop during product changeovers without adding external physical stops.
When replacing an ISO 15552 cylinder, match the 200mm bore, 40mm stroke, 10mm adjustment range, G3/4 port, and desired mounting interface. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the stroke is under 300mm, external guide support is less critical than on longer strokes, though the 40mm rod diameter already handles substantial side loads.
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 SAIJ200X40-10 FAQ
It can reach a maximum push force of 3204 kgf at 1.0MPa.
The rear adjuster screw allows you to shorten the 40mm nominal stroke by up to 10mm, providing a usable travel window of 30-40mm. This stopper only sets the end position and decelerates the load; it does not lock or hold the load without continuous air pressure.
