About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X800-30S
The AirTAC SAIJ200X800-30-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers massive thrust, pushing 15708 N at 0.5 MPa, making it suited for heavy-duty industrial handling. An integrated magnet enables position sensing with CMSE reed or DMSE electronic switches.
This model features an 800 mm nominal stroke that can be dialed back by up to 30 mm, creating a precise 770-800 mm usable travel window. The extruded aluminum barrel includes sensor grooves on both sides, and the carbon steel rod features an M36x2 thread. It operates at 30-500 mm/s and includes adjustable air cushions at both ends to decelerate massive loads smoothly.

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 SAIJ200X800-30S Is Used
Heavy Machinery Setup
Fine-tune the 770-800 mm stroke end-position during heavy machinery commissioning without swapping cylinders or adding external stopper blocks.
Product Changeover
Quickly adjust the rear stopper by up to 30 mm to accommodate varying large product sizes on an automated assembly line.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X800-30S the Right Cylinder?
The rear adjuster functions strictly as a mechanical stop for commissioning fine-tuning and cannot hold a load without live air; for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder. As a dimensionally interchangeable ISO 15552 profile cylinder, it matches standard bore, stroke, PT port, and mounting dimensions.
Because the 800 mm stroke is substantial, the 40 mm carbon steel rod and M36x2 thread provide robust support, but an external guide is strongly recommended to prevent excessive side-loading on the piston. This SAIJ model supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.
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 SAIJ200X800-30S FAQ
At the maximum 1.0 MPa pressure, it delivers up to 3204 kgf.
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the effective stroke within a 770-800 mm travel window. It only sets the end position and does not lock the load without continuous air pressure.
