About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X750-40S
The AirTAC SAIJ200X750-40-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the effective travel back by up to 40 mm. This yields a usable 710-750 mm travel window, allowing precise end-position tuning at commissioning without bolting on external stops.
It uses a robust 40 mm carbon steel rod with an M36x2 thread to handle heavy loads, though the 750 mm stroke length requires an external guide to prevent excessive side-loading. The extruded aluminum barrel includes sensor grooves on both sides, and because this is a -S model, it supports CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts purely as a travel stop and 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 SAIJ200X750-40S Is Used
Heavy Press Tuning
Dial in the exact 710-750 mm end-stop for large metal forming or heavy press operations without changing the cylinder.
Pallet Changeover
Adjust the retract position on the fly to accommodate different pallet sizes on long-stroke material handling conveyors.
Large Assembly Setup
Fine-tune the end position during machine commissioning to time heavy 200 mm bore automation sequences perfectly.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X750-40S the Right Cylinder?
Select this 200 mm bore cylinder when your application requires maximum thrust up to 3204 kgf at 1.0 MPa and a long 750 mm stroke that needs fine-tuning within a 710-750 mm window. If you need less force, stepping down to a 160 mm bore yields 10053 N at 0.5 MPa. Choose this adjustable-stroke SAIJ over a fixed SAI when you need variable end-stops for product changeovers. To replace an ISO 15552 cylinder, match the 200 mm bore, 750 mm stroke, 40 mm adjust, PT tapered G3/4 port, and the -S magnet. For load-holding without live air, use a SAIL or BSAI lock instead of this adjuster.
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 SAIJ200X750-40S FAQ
At 0.7 MPa, the push force increases to 21991 N.
The rear adjuster screw lets you shorten the 750 mm nominal stroke by up to 40 mm, creating a 710-750 mm usable travel window. It acts as a stop and does not lock the load without air pressure.
