About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X55-10S
The AirTAC SAIJ200X55-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 45 to 55 mm. The extruded aluminum barrel features sensor grooves on both sides, and the integrated -S magnet supports precise position detection using CMSE reed or DMSE electronic solid-state switches.
This adjustable-stroke design allows operators to fine-tune the retract end-position at commissioning without swapping out the entire cylinder or adding external mechanical stops. The rear adjuster functions purely as a travel stop to set the end of stroke and relies on the built-in variable air cushions for end-of-travel deceleration; it is not a locking mechanism and will not hold a load without continuous live air pressure.

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 SAIJ200X55-10S Is Used
Heavy Press Tonnage Setup
Fine-tune the 45-55 mm travel window during initial press commissioning to dial in the exact contact position for massive 15708 N forming forces without external spacers.
Product Size Changeover
Quickly adjust the retract stop on automated heavy-duty assembly lines when switching between product variants, saving downtime by using the rear screw rather than replacing cylinders.
Large Fixture Clamping
Secure massive workholding fixtures with up to 3204 kgf, using the 10 mm stroke adjustment to compensate for varying material thicknesses while monitoring clamp position via DMSE sensors.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X55-10S the Right Cylinder?
Selecting this 200 mm bore model is ideal when an application requires massive thrust, such as 21991 N at 0.7 MPa, combined with a very short 55 mm stroke that needs exact end-position tuning. For applications needing true load-holding without constant air pressure, a standard SAIJ is insufficient; you should consider the AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder series instead.
To match this ISO 15552 footprint for a direct replacement, verify the 200 mm bore, 55 mm stroke, 10 mm adjustment range, PT port thread, and the -S magnet option. The SAIJ series supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets. Because the 40 mm rod and M36x2 thread handle substantial side loads, ensure your mounting configuration properly supports the cylinder to prevent binding during operation.
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 SAIJ200X55-10S FAQ
The rear adjuster acts as an external stopper that allows you to shorten the nominal 55 mm stroke by up to 10 mm, creating an effective 45 to 55 mm travel window. This enables precise end-position tuning at commissioning without changing the cylinder or adding external stops, though the adjuster only sets the travel end and does not lock the load without live air.
