About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X375-30
The AirTAC SAIJ200X375-30 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 345-375 mm usable travel window by allowing you to trim the nominal 375 mm stroke back by up to 30 mm.
This extruded aluminum barrel design includes sensor grooves on both sides for CMSE or DMSE switches. The rear adjuster acts purely as a mechanical stop for end-position tuning; it does not lock the load without live air. For position holding, an external pilot-operated check valve or an AirTAC SAIL lock cylinder is required.

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 SAIJ200X375-30 Is Used
Heavy Press Tuning
Dial in the exact 345-375 mm end position for massive pressing operations without replacing the cylinder during product line changeovers.
Large Assembly Jigs
Adjust the stroke stopper on the factory floor to accommodate varying large-component sizes quickly and efficiently.
Custom End-Stop Calibration
Fine-tune the retract end position during commissioning to perfectly align heavy tooling, avoiding the need for external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X375-30 the Right Cylinder?
Selecting this 200 mm bore model makes sense when your application requires the highest thrust class, as stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053 N. The 30 mm adjustment range is highly valuable for machine setup and product changeovers, allowing you to fine-tune the end stop without swapping cylinders or adding external shims. Unlike a fixed-stroke SAI cylinder, this SAIJ variant offers built-in flexibility for varying end positions.
When configuring your ISO 15552 replacement, match the 200 mm bore, 375 mm stroke, PT tapered port threads, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 375 mm stroke exceeds 300 mm, the long unsupported travel necessitates an external guide to prevent excessive rod side-loading and premature seal wear.
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 SAIJ200X375-30 FAQ
The operational speed range is 30-500 mm/s, and it uses a G3/4 port.
The rear adjuster screw lets you shorten the nominal 375 mm stroke by up to 30 mm, creating a 345-375 mm travel window. This mechanical stop fine-tunes the end position but does not hold the load without live air pressure.
