About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X500-100
The AirTAC SAIJ200X500-100 is a double-acting ISO 15552 profile cylinder featuring a 200 mm bore and a rear stroke adjuster that permits up to 100 mm of travel reduction. This creates a usable stroke window of 400 to 500 mm, allowing you to fine-tune the retract end position during commissioning without adding external stops. Operating at 1.0 MPa, it delivers a maximum thrust of 3204 kgf, making it suitable for heavy-duty press and lift operations.
The extruded aluminum barrel incorporates sensor grooves on both sides for flexible switch mounting. It uses a robust 40 mm carbon steel rod with an M36x2 thread, providing excellent rigidity and side-load resistance. The rear adjuster acts purely as a mechanical stop to set the end position; it does not lock or hold the load pneumatically, meaning live air pressure is required to maintain force.

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 SAIJ200X500-100 Is Used
Heavy Press Operations
Dial in the exact 400-500 mm end position for varying material thicknesses during heavy pressing without physically swapping cylinders.
Multi-Product Changeover
Rapidly adjust the retract stop during production line changeovers to accommodate different packaging sizes or pallet dimensions.
Large Assembly Fixtures
Fine-tune the clamping travel on large automated assembly fixtures, ensuring precise end-positioning without complex external stopper hardware.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X500-100 the Right Cylinder?
Choose this 200 mm bore model when your application requires maximum thrust up to 3204 kgf. If your force requirements are lower, stepping down to the 160 mm bore yields 2050 kgf at the same 0.5 MPa baseline, which may optimize energy use. The adjustable 400-500 mm travel window is ideal for production lines running multiple product sizes, as the end-stop can be dialed in during changeovers rather than physically swapping a fixed-stroke SAI cylinder.
Because this cylinder features a 500 mm stroke, the long unsupported piston travel increases the risk of rod sag and side-loading; an external guide rail is strongly recommended to prevent premature seal wear. To replace this unit with an equivalent ISO 15552 cylinder, match the 200 mm bore, 500 mm stroke, 100 mm adjustment, PT G3/4 port, and standard carbon steel rod. Note that the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

- ✓ 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 SAIJ200X500-100 FAQ
At the maximum operating pressure of 1.0 MPa, this 200 mm bore cylinder generates a push force of 3204 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the nominal 500 mm stroke by up to 100 mm, creating a usable travel window of 400 to 500 mm. It functions as a travel stop, not a lock, so it cannot hold the load without live air pressure.
