Airtac SAIJ200 Adjustable Cylinder SAIJ200X950-40
The AirTAC SAIJ200 Adjustable Cylinder SAIJ200X950-40 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 950mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X950-40
It features a robust 40mm carbon steel rod and a G3/4 PT tapered port. A rear mechanical stopper allows you to fine-tune the effective travel, creating a usable stroke window between 910 and 950mm without requiring external stops.
This adjustable travel range is ideal for dialing in exact end positions during machine commissioning or product changeovers. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting, and the system operates at speeds of 30-500mm/s. The rear adjuster acts purely as a travel stop to set the retraction endpoint, not as a lock, meaning live air pressure is required to maintain the load.

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 SAIJ200X950-40 Is Used
Heavy Machinery Setup
Fine-tune the 910-950mm retraction endpoint during heavy machinery commissioning to achieve precise alignment without machining new hard stops.
Product Size Changeovers
Quickly adapt a heavy-duty conveyor sorting arm to handle different pallet sizes by dialing back the stroke up to 40mm via the rear adjuster.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X950-40 the Right Cylinder?
Selecting this 200mm bore cylinder is appropriate when your application requires extreme thrust, such as 15708N at 0.5 MPa or up to 3204 kgf at the maximum 1.0 MPa operating pressure. If your force requirements are lower, stepping down to a 160mm bore provides 10053N at 0.5 MPa, which may reduce air consumption. The 40mm adjustment range is chosen when you need precise mechanical tuning of the retract position over a 910-950mm window, avoiding the need to physically swap cylinders for slightly different product sizes.
Because this model features a long 950mm stroke, the 40mm carbon steel rod will experience significant leverage forces when fully extended. An external guide mechanism is strongly recommended to prevent excessive side-loading and premature seal wear. To replace an existing ISO 15552 cylinder, match the 200mm bore, 950mm stroke, 40mm adjustment, G3/4 PT port, and your required mounting style. Note that SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR options. For applications requiring the load to be held without continuous air pressure, consider the SAIL or BSAI series instead.
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 SAIJ200X950-40 FAQ
At the maximum rated pressure of 1.0 MPa, it can deliver a maximum push force equivalent to 3204 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the nominal 950mm stroke by up to 40mm, providing an effective travel window of 910 to 950mm. It functions as a travel stop and does not lock the load without live air pressure.
