About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X700-30S
The AirTAC SAIJ200X700-30-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The built-in rear adjusting screw allows you to fine-tune the effective travel within a 670 to 700 mm window, making it ideal for dialing in exact end positions during machine commissioning without needing external stops.
This bore features a robust 40 mm carbon steel piston rod and a G3/4 PT tapered port. Because the barrel is an extruded aluminum profile rather than a tie-rod design, it integrates cleanly into modern ISO 15552 footprints. The -S magnet option enables position detection using AirTAC CMSE reed switches or DMSE solid-state electronic sensors, while the reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) omits FB and CA 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 SAIJ200X700-30S Is Used
Heavy Press Fine-Tuning
Dial in exact end positions during heavy press commissioning using the 670-700 mm adjustable window, avoiding the need to swap cylinders for slight position corrections.
Product Size Changeover
Quickly adapt automated lines to different product lengths by turning the rear adjuster up to 30 mm, eliminating downtime associated with re-machining fixed external stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X700-30S the Right Cylinder?
Select this 200 mm bore when an application requires extreme force—up to 21991N at 0.7 MPa—that smaller bores cannot provide; for comparison, the 160 mm bore yields 14074N at the same pressure. The adjustable 670-700 mm travel window is highly beneficial for product changeovers or setup refinement, letting operators trim the stroke by up to 30 mm rather than machining new hard stops. For any 700 mm stroke, the long unsupported rod length requires an external guide to prevent excessive side-loading and premature seal wear.
When specifying a replacement, match the 200 mm bore, 700 mm stroke, 30 mm adjustment, G3/4 PT port, and -S magnet. Remember that the rear adjuster acts purely as a travel stop for deceleration and does not hold the load without live air. For true fail-safe load-holding, consider the SAIL pneumatic lock or BSAI clamp-lock cylinder series instead of relying on the cushion or stopper.
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 SAIJ200X700-30S FAQ
The rear adjusting screw acts as a mechanical stop that lets you shorten the effective stroke from 700 mm down to 670 mm. It fine-tunes the travel end for commissioning but does not lock or hold the load without continuous air pressure.
