About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X210-20S
The AirTAC SAIJ200X210-20-S is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty pneumatic tasks. Fitted with a rear mechanical adjuster, it allows you to fine-tune the travel window down to 190-210mm from the 210mm nominal stroke without adding external stops. It delivers a robust 15708N push force at 0.5MPa and includes a standard magnet for position sensing.
This 200mm bore unit uses a G3/4 PT tapered port and a 40mm carbon steel rod with an M36x2 thread to handle substantial side loads. The extruded aluminum barrel incorporates dual sensor grooves compatible with CMSE reed and DMSE solid-state switches. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X210-20S Is Used
Heavy Press Fine-Tuning
Dial in the exact 190-210mm end position during heavy press commissioning to accommodate material thickness variations without swapping cylinders.
Product Changeover Stops
Adjust the retract stopper by up to 20mm to handle different product lengths on a heavy-duty conveyor line during rapid SKU changeovers.
Large Fixture Positioning
Set precise travel limits for large automated welding or clamping fixtures where exact end-of-stroke positioning is critical for joint quality.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X210-20S the Right Cylinder?
Select this 200mm bore cylinder when your application requires extreme thrust, such as 15708N push at 0.5MPa, and you need precise end-position tuning during commissioning. If your force requirements are lower, stepping down to a 160mm bore provides 10053N push force, which may offer a more compact footprint. The adjustable rear stopper is strictly a travel limiter and does not hold the load without live air; for fail-safe load holding, consider the SAIL or BSAI series.
With a 210mm stroke, this model operates safely within the 30-500mm/s speed range for large bores. Because the stroke exceeds 300mm on related configurations, always ensure an external guide is used to prevent excessive rod deflection. This configuration specifies PT tapered ports, a carbon steel rod, and the -S magnet option for CMSE/DMSE sensor integration.

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 SAIJ200X210-20S FAQ
At a 0.5MPa operating pressure, this 200mm bore cylinder generates a push force of 15708N and a pull force of 15080N. At the maximum 1.0MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from 210mm down to 190mm. This allows for fine-tuning the end position during setup, though it does not lock the load without continuous air pressure.
