About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X270-100
The AirTAC SAIJ200X270-100 is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical adjuster. It provides a nominal 270 mm stroke that can be dialed back by up to 100 mm, yielding a usable travel window of 170 to 270 mm. This allows operators to fine-tune the retract end-position during commissioning without adding external stops.
The 40 mm carbon steel piston rod and M36x2 thread provide a robust interface capable of handling substantial loads, though long unsupported strokes still necessitate an external guide to prevent side-loading damage. This model features PT tapered G3/4 ports and variable air cushions at both ends to decelerate heavy moving masses. It uses the standard SAIJ mounting set, including Basic, FA, LB, TC, FTC, TCM1, and TCM2, intentionally omitting FB, CA, CB, and CR brackets.

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 SAIJ200X270-100 Is Used
Heavy Press Tuning
Dial in the exact 170 to 270 mm retract distance during heavy-duty press setup, allowing precise positioning without machining custom spacers.
Product Changeover
Quickly adapt a large automated assembly line to new product sizes by turning the rear adjuster to shift the end-stop within the 100 mm window.
Large Jig Alignment
Fine-tune the end position of heavy fabrication jigs at commissioning, using the robust 40 mm rod to maintain structural integrity under high side loads.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X270-100 the Right Cylinder?
Select this 200 mm bore cylinder when an application requires extreme force alongside flexible end-positioning, such as large press or heavy material handling setups. The adjustable stroke is chosen over a fixed SAI cylinder when a machine requires variable end-stops to accommodate product changeovers without physically swapping out the actuator.
When integrating this component, remember the rear adjuster functions strictly as a travel stop, not a lock. The SAIJ200X270-100 cannot hold its load without live air pressure; for fail-safe load-holding, consider an AirTAC SAIL or BSAI series cylinder. To replace this unit, match the 200 mm bore, 270 mm stroke, 100 mm adjustment, PT G3/4 port, and the appropriate mounting bracket. Note that because the nominal stroke is 270 mm, an external guide rail is recommended to support the rod and prevent binding during extension.
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 SAIJ200X270-100 FAQ
At the maximum 1.0 MPa pressure, it delivers up to 3204 kgf.
The rear adjuster acts as a mechanical stop that shortens the effective stroke. For this 270 mm stroke model, you can trim the retract travel back by up to 100 mm, creating a usable travel window of 170 to 270 mm. It does not lock the load without live air.
