About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X650-50S
The AirTAC SAIJ200X650-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering massive thrust up to 15708N at 0.5 MPa. It features a 650mm nominal stroke that can be fine-tuned backward by up to 50mm, yielding a precise 600-650mm usable travel window for exact end-position calibration. The extruded aluminum barrel includes dual sensor grooves, and this -S variant hosts a magnet for CMSE reed and DMSE solid-state switches.
This heavy-duty actuator uses a robust 40mm carbon steel rod with M36x2 threads to handle high side-loads, while PT tapered ports seal securely against high-pressure air. The rear adjuster functions strictly as a travel stop to dial in the retract position without adding external physical stops, but it will 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 SAIJ200X650-50S Is Used
Heavy Press Tuning
Dial in the exact 600-650mm retract position during machine commissioning to set precise stamping depths without adding external mechanical stops.
Product Changeover
Quickly shorten the effective stroke by up to 50mm when switching the production line to a different product size, saving tooling swap time.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X650-50S the Right Cylinder?
If your application needs less force, stepping down to a 160mm bore yields 10053N, making this 200mm unit ideal for heavy presses. The 50mm adjustment window is perfect for product changeovers, allowing you to trim the 650mm travel down to 600mm without swapping the cylinder.
Because the stroke is 650mm, the long unsupported rod requires an external guide to prevent sagging and premature wear. For drop-load safety, note that this plain SAIJ cylinder does not hold position without live air; the rear adjuster is a stop, not a lock. Use a SAIL or BSAI cylinder for fail-safe load holding. As a dimensionally interchangeable ISO 15552 profile cylinder, it matches standard bore, stroke, PT port, and Basic, FA, LB, TC, FTC, TCM1, TCM2 mounting footprints.

- ✓ 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 SAIJ200X650-50S FAQ
The operational speed range for this 200mm bore is 30-500 mm/s.
The rear adjuster acts as a mechanical stop that lets you trim the 650mm stroke back by up to 50mm, creating a 600-650mm travel window. It is a stop for end-position tuning, not a lock, and will not hold the load without continuous air pressure.
