Airtac SAIJ200 Adjustable Cylinder SAIJ200X900-75
The AirTAC Airtac SAIJ200 Adjustable Cylinder SAIJ200X900-75 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 900mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X900-75
The AirTAC SAIJ200X900-75 is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty positioning tasks. It features a rear mechanical adjuster that allows you to fine-tune the effective travel window from 825 to 900 mm without physically swapping the unit or adding external stops. Delivering a robust 21991 N of push force at 0.7 MPa, this 200 mm bore actuator handles substantial payloads while operating at a controlled speed of 30-500 mm/s.
This extruded aluminum barrel design includes dual-side sensor grooves for straightforward position detection. The 40 mm carbon steel piston rod and M36x2 thread provide high structural rigidity, which is critical for maintaining alignment over the 900 mm stroke. The rear adjuster acts strictly as a travel stop to set deceleration and end positions; it does not hold the load without continuous air pressure, so a SAIL or BSAI lock variant is required for fail-safe holding.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200X900-75 Is Used
Heavy Press Positioning
Dial in the exact 825-900 mm end-stop during press setup to accommodate varying material thicknesses without changing out the cylinder.
Large Pallet Diverter
Adjust the retract distance on the fly during line changeovers to handle different pallet sizes while moving heavy loads.
Automated Assembly Station
Fine-tune the stroke end-position during initial commissioning to perfectly seat large components without adding external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X900-75 the Right Cylinder?
Select this 200 mm bore model when your application demands high thrust—up to 21991 N at 0.7 MPa—and requires exact end-position tuning during commissioning or product changeovers. If you need to step down the force, the neighboring 160 mm bore provides 14074 N at the same pressure. For any stroke length of 900 mm, the 40 mm rod carries significant side-load risks; always pair this cylinder with an external guide to prevent rod binding and premature seal wear.
To replace an existing ISO 15552 actuator, match the 200 mm bore, 900 mm nominal stroke, 75 mm adjustment range, PT (tapered) G3/4 port, and your required mounting hardware. The SAIJ series supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting the FB, CA, CB, and CR options. Because no -S magnet is specified here, it will not support CMSE or DMSE solid-state sensors out of the box.
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 SAIJ200X900-75 FAQ
At a standard 0.7 MPa operating pressure, this 200 mm bore cylinder generates 21991 N of push force and 15080 N of pull force. It can deliver up to 28274 N push force at its maximum 1.0 MPa pressure.
The rear adjuster screw lets you mechanically shorten the effective travel from the nominal 900 mm down to 825 mm. This creates a 75 mm tuning window for setting exact end-positions during commissioning, but it functions as a stop and does not lock the load without live air pressure.
