About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X350-20
The AirTAC SAIJ200X350-20 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 15708 N at 0.5 MPa and pulling 15080 N, making it suited for heavy-duty automation. The built-in adjusting screw provides a usable travel window of 330-350 mm, allowing you to trim the effective stroke by up to 20 mm during commissioning without swapping the cylinder.
This model features a robust 40 mm carbon steel rod with an M36x2 thread, engineered to handle substantial side loads, though at 350 mm of travel an external guide is still recommended for optimal longevity. It uses a G3/4 PT tapered port and includes variable air cushions at both ends to decelerate heavy masses. For position feedback, adding a magnet (-S) allows the use of CMSE reed or DMSE electronic sensors in the dual-side barrel grooves.

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 SAIJ200X350-20 Is Used
Heavy Assembly Pressing
Dials in the exact 330-350 mm end-position for pressing heavy components, ensuring precise seating without re machining hard stops.
Pallet Changeover Systems
Adjusts the stroke on the fly to accommodate different pallet sizes on a packaging line, using the 20 mm trim to adapt the retract position.
Large Fixture Actuation
Provides up to 3204 kgf of holding power against a fixture while allowing technicians to fine-tune the travel limit during machine setup.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X350-20 the Right Cylinder?
Select this 200 mm bore actuator when your application requires extreme force that smaller bores cannot provide, such as shifting heavy pallets or pressing assemblies. The adjustable 330-350 mm window is perfect for applications requiring variable end-stops or frequent product-size changeovers, replacing the need for fixed-stroke SAI cylinders and external mechanical stops.
When integrating this cylinder, match your mounting needs to the available SAIJ options: Basic, FA, LB, TC, FTC, TCM1, or TCM2 (note that FB, CA, CB, and CR mounts are omitted from this series). Because the rear adjuster and air cushions only decelerate the load, they do not function as a lock; if your process requires load-holding without live air pressure, consider an external rod lock or the AirTAC SAIL or BSAI series. This profile cylinder is dimensionally interchangeable per ISO 15552.
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 SAIJ200X350-20 FAQ
At its maximum operating pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjuster screw acts as a mechanical stop that allows you to shorten the 350 mm nominal stroke by up to 20 mm, creating a usable travel window of 330-350 mm. It is a travel stop and deceleration point, not a lock, so it will not hold the load without continuous air pressure.
