About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X800-75
The AirTAC SAIJ200X800-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits up to 75 mm of travel reduction. This yields a usable stroke window of 725-800 mm, enabling precise end-position tuning during commissioning without adding external stops. As an extruded aluminum profile barrel, it integrates seamlessly into ISO 15552 mounting interfaces.
The 40 mm carbon steel rod and M36x2 thread provide substantial rigidity, though the 800 mm length necessitates an external guide to manage side loads. The rear adjuster acts strictly as a travel stop, not a lock, so live air is required to hold position.

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 SAIJ200X800-75 Is Used
Large Press Toning
Dial in the exact 725-800 mm end-stop for heavy pressing operations, allowing precise toning adjustments without replacing the cylinder.
Product Line Changeover
Quickly adapt a long-stroke automated line to new product sizes by turning the rear adjuster, shifting the effective travel window instantly.
Heavy Machinery Setup
Fine-tune the extended position of heavy material handling equipment during commissioning to avoid mechanical crashes and optimize cycle timing.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X800-75 the Right Cylinder?
Choose this adjustable model over a fixed SAI when a machine requires variable end-stops or product-size changeovers, saving the effort of physically swapping cylinders. To replicate this exact ISO 15552 replacement, match the 200 mm bore, 800 mm stroke, 75 mm adjustment, PT G3/4 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is 800 mm, an external guide is mandatory to prevent excessive side-load wear on the rod bearings.
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 SAIJ200X800-75 FAQ
At its maximum operating pressure of 1.0 MPa, it achieves a peak thrust of 3204 kgf.
A rear screw stopper lets you shorten the 800 mm nominal stroke by up to 75 mm, creating a 725-800 mm adjustable travel window. This stopper only sets the end position; it does not lock the load without live air.
