About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X900-30S
The AirTAC SAIJ200X900-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the retract end-position. With a nominal 900 mm stroke and a 30 mm adjustment range, it provides an exact 870-900 mm usable travel window for precise commissioning without external stops. It delivers massive thrust, pushing with 15708 N and pulling with 15080 N at 0.5 MPa, scaling up to 3204 kgf at 1.0 MPa.
This large-bore unit includes a magnet for CMSE and DMSE sensors, utilizing the dual sensor grooves machined into the extruded aluminum barrel. The robust 40 mm carbon steel rod and M36x2 thread handle high side-loads, while the PT tapered port threads ensure a tight, high-pressure pneumatic seal. The rear adjuster functions purely as a travel stop to set the end position; it does not lock or hold the load without live air pressure.

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 SAIJ200X900-30S Is Used
Heavy Press Tuning
Dial in the exact 870-900 mm travel window during heavy press commissioning to accommodate material thickness variations without remounting the cylinder.
Product Changeover
Quickly adjust the retract end-stop on a production line when switching to a different pallet or product size, minimizing downtime.
Variable End-Stop Setup
Use the rear screw to set precise retract positions for large automated machinery, eliminating the need to bolt on external physical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X900-30S the Right Cylinder?
The 30 mm adjustable stroke is ideal for machine setups requiring variable end-stops or product changeovers, saving the effort of swapping a fixed-stroke SAI cylinder. For load-holding without continuous air pressure, this standard cylinder is insufficient; you must integrate an external rod lock or select a related SAIL or BSAI clamp-lock cylinder.
Because this unit features a long 900 mm stroke, an external guide rail is strongly recommended to prevent rod binding and premature seal wear under heavy side-loads. When matching this ISO 15552 footprint, ensure you specify the 200 mm bore, 900 mm stroke, 30 mm adjustment, PT port threads, and the -S magnet option. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.

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 SAIJ200X900-30S FAQ
At the maximum operating pressure of 1.0 MPa, it delivers up to 3204 kgf.
The rear adjuster screw lets you trim the effective travel back by up to 30 mm, creating an 870-900 mm usable window. It acts as a mechanical stop to fine-tune the end position and does not hold the load without live air pressure.
