About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X900-50S
The AirTAC SAIJ200X900-50-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers substantial thrust, pushing with 15708 N and pulling with 15080 N at 0.5 MPa, while operating at a 30-500 mm/s speed range. Equipped with a standard carbon steel rod and a PT tapered port thread, this 200 mm bore unit provides a usable travel window of 850-900 mm by allowing you to dial back the 900 mm nominal stroke by up to 50 mm.
Because the adjuster acts purely as a mechanical stop at the retract end, it enables precise end-position tuning during commissioning without swapping the cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches. This model uses the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and relies on variable air cushions at both ends to decelerate the load.

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 SAIJ200X900-50S Is Used
Product Size Changeovers
Dial in the 50 mm stroke adjustment during line changeovers to accommodate varying package lengths without physically replacing the cylinder.
Press Fine-Tuning
Use the 850-900 mm travel window to precisely set the retract end-position during initial commissioning, avoiding the need for external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X900-50S the Right Cylinder?
Choose this 200 mm bore if your application requires maximum force, as stepping down to a 160 mm bore drops your 0.5 MPa push thrust to 10053 N. The adjustable stroke is ideal for machine setups requiring variable end-stops or product-size changeovers, giving you a 50 mm fine-tuning window. For a fixed end-position without the adjuster, the standard SAI cylinder is the alternative. Since the 900 mm stroke is substantial, you must use an external guide to prevent excessive side-loading on the 40 mm rod and M36x2 thread. Remember that the rear adjuster and air cushions only decelerate travel; they do not hold the load without live air. For fail-safe load holding, select a SAIL (air-released lock) or BSAI (clamp-lock) cylinder.
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 SAIJ200X900-50S FAQ
If you need maximum force at 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjuster acts as a mechanical stop that lets you shorten the 900 mm nominal stroke by up to 50 mm, creating an 850-900 mm usable travel window. It functions as a travel stop and deceleration point, not a lock, so it will not hold the load without live air pressure.
