About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X55-30
The AirTAC SAIJ200X55-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 25 to 55 mm, allowing you to dial back the nominal 55 mm stroke by up to 30 mm during machine setup.
Unlike a fixed-stroke SAI, this model lets you fine-tune the retract end position without swapping the cylinder or adding external stopper blocks. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic sensors. Note that the rear adjuster acts only as a travel stop; it does not hold the load without 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 SAIJ200X55-30 Is Used
Product Changeovers
Quickly adapt the stroke window from 25 to 55 mm on a packaging line without physically replacing the cylinder or bolting on external stops.
Clamping Fixtures
Secure heavy workpieces in machining fixtures, relying on the robust 40 mm carbon steel rod and M36x2 thread to handle high side loads.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X55-30 the Right Cylinder?
If you need less thrust, stepping down to a 160 mm bore provides 10053 N, which might better suit medium-duty handling without oversizing your pneumatic valves. The PT tapered port threads and G3/4 air supply match the high flow requirements of this bore size.
The 30 mm adjustment range is perfect for product changeovers where exact end-position tuning is required at commissioning. Because the 55 mm stroke is relatively short, side-load risks are minimal, but you should still ensure the load is guided to prevent binding. For applications that must hold position without continuous air pressure, consider the SAIL series with an air-released lock or the BSAI clamp-lock cylinder instead of relying on this adjuster. This unit is dimensionally interchangeable per ISO 15552 and uses the standard SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ200X55-30 FAQ
The rear adjuster screw lets you shorten the effective travel by up to 30 mm, giving a usable stroke window of 25 to 55 mm. It acts as a mechanical stop to fine-tune the end position and does not function as a lock.
It can deliver a maximum thrust of 3204 kgf at 1.0 MPa.
