About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X270-50
The AirTAC SAIJ200X270-50 is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical adjuster, allowing you to dial back the nominal 270 mm stroke by up to 50 mm. This creates a precise 220-270 mm usable travel window, ideal for fine-tuning the retract position at commissioning without swapping hardware. As an extruded aluminum profile cylinder, it is dimensionally interchangeable with ISO 15552 cylinders.
It features a robust 40 mm carbon steel rod with an M36x2 thread, G3/4 PT tapered ports, and 50 mm variable air cushions at both ends. The dual sensor grooves on the barrel accept CMSE reed or DMSE electronic switches if a magnet is specified later.

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 SAIJ200X270-50 Is Used
Heavy Press Tuning
Dial in the exact 220-270 mm retract position on large presses during setup, using the 50 mm rear adjuster to compensate for tooling variances without external stops.
Product Line Changeover
Adapt a heavy-duty conveyor or lift station to new product sizes by shifting the end-stop within the adjustment window, avoiding complete cylinder replacement.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X270-50 the Right Cylinder?
The adjustable stroke is perfect for product changeovers, letting you shift the end-stop by up to 50 mm rather than installing a fixed-stroke SAI cylinder. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for dead-load holding, consider an external rod lock, a pilot-operated check valve, or the AirTAC SAIL and BSAI locking cylinders.
Because the 270 mm stroke is substantial, the heavy 40 mm rod and M36x2 thread handle high stresses, but an external guide is recommended to prevent side-loading damage on long travels. This model uses the standard SAIJ mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR mounts. Operating speed ranges from 30-500 mm/s.
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 SAIJ200X270-50 FAQ
At its maximum operating pressure of 1.0 MPa, it delivers up to 3204 kgf.
The rear adjuster acts as a mechanical stop that trims the nominal 270 mm stroke back by up to 50 mm, creating a 220-270 mm usable travel window. It only sets the end position and does not lock the load without live air pressure.
