About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX400-10
The AirTAC SAIJ200X400-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits up to 10mm of end-position trimming. This creates a usable travel window between 390 and 400mm, enabling precise fine-tuning during commissioning without adding external stops. It delivers massive thrust, providing 21991N of push force at 0.7MPa and reaching 28274N at 0.9MPa.
Equipped with a robust 40mm piston rod and M36x2 thread, this large-bore unit handles heavy loads effectively. The rod is constructed from SUS420J2 stainless steel for enhanced durability, and the barrel features sensor grooves on both sides for flexible switch mounting. It uses PT tapered ports sized G3/4 and operates at speeds of 30-500mm/s.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX400-10 Is Used
Heavy Machinery Setup
Dial in the exact 390-400mm end-stop during heavy equipment commissioning to perfect process positioning without machining custom spacers.
Product Changeover
Quickly adjust the stroke by up to 10mm on automated lines handling varying large product sizes, ensuring precise physical stops for each run.
Press Positioning
Utilize the 28274N push force at 0.9MPa for heavy pressing tasks while retaining the ability to fine-tune the bottoming position for different material thicknesses.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX400-10 the Right Cylinder?
Choose this 200mm bore cylinder when your application requires the highest force output, pushing 21991N at 0.7MPa. If your process demands less than 15000N, stepping down to a 160mm bore is more efficient. The 10mm rear adjustment screw is ideal for variable end-stops or product changeovers, functioning as a travel stop rather than a lock. For load-holding without live air pressure, consider an external rod lock or the AirTAC SAIL series. Because the 400mm stroke is substantial, always use an external guide to prevent excessive side-loading on the rod.
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 SAIJ200AX400-10 FAQ
At an operating pressure of 0.9 MPa, this 200mm bore cylinder generates a maximum push force of 28274 Newtons. At 0.7 MPa, it delivers 21991 Newtons of push force.
The rear adjuster acts as a mechanical stop that allows you to shorten the 400mm nominal stroke by up to 10mm, providing an effective travel window of 390-400mm. It only sets the end position and does not lock the load without live air pressure.
