About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X800-100S
The AirTAC SAIJ200X800-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. This allows you to dial back the nominal 800mm stroke precisely during commissioning without adding external stops.
The 200mm bore uses a robust 40mm carbon steel rod and a G3/4 PT port. Integrated variable air cushions at both ends decelerate the heavy moving loads typical of this bore size. The extruded aluminum barrel includes sensor grooves on both sides, and the -S magnet option supports CMSE reed and DMSE electronic solid-state switches for precise position feedback.

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 SAIJ200X800-100S Is Used
Large Press Tolerance Setup
Dial in the exact 700-800mm end-stop during heavy press commissioning to accommodate material thickness variations without swapping the cylinder.
Variable Stroke Ejection
Adjust the ejection distance on a heavy-duty manufacturing line to safely clear different product sizes during machine changeover.
Long-Stroke Position Tuning
Fine-tune the retract position on a long-stroke assembly station to perfectly align large components before final clamping.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X800-100S the Right Cylinder?
Choose this adjustable-stroke model when an application requires fine-tuning of the retract end-position on a 200mm bore line, yielding up to 15708N at 0.5 MPa. If you need less force, stepping down to a 160mm bore provides 10053N at 0.5 MPa. The rear adjuster acts purely as a travel stop and does not hold the load without live air; for true fail-safe load holding, select the SAIL or BSAI series.
With an 800mm stroke, the 40mm rod and M36x2 thread provide a strong interface, but long unsupported travel demands an external guide to manage side loads. This cylinder is dimensionally interchangeable with ISO 15552 cylinders and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).
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 SAIJ200X800-100S FAQ
The rear adjuster allows you to shorten the effective stroke by up to 100mm. This creates a usable travel window of 700-800mm, letting you fine-tune the end position at commissioning without changing the physical cylinder.
It operates at speeds between 30-500 mm/s and handles a maximum standard stroke of 1500mm.
