About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX240-10
The AirTAC SAIJ200X240-10 is a double-acting, single-rod ISO 15552 profile cylinder engineered for heavy-duty applications. It features a rear mechanical adjuster that permits you to trim the effective travel back by up to 10 mm, creating a precise 230-240 mm usable window for dialing in end positions at commissioning. Delivering 15708 N of push force at 0.5 MPa and a maximum of 3204 kgf at 1.0 MPa, this 200 mm bore unit handles massive loads without requiring external stops.
This model is equipped with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel incorporates sensor grooves on both sides, allowing you to mount CMSE reed or DMSE electronic sensors if position feedback is required later. The rear adjuster acts strictly as a travel stop to set deceleration, meaning it will not hold the load safely without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX240-10 Is Used
Heavy Press Tuning
Dial in the exact 230-240 mm end-of-stroke position during machine commissioning to ensure precise pressing force on large industrial assemblies.
Product Changeovers
Quickly adjust the rear stopper by up to 10 mm to accommodate slight variations in product sizes on a high-tonnage production line without changing cylinders.
Massive Load Positioning
Leverage the 3204 kgf maximum thrust to move and position heavy materials, using the fine adjustment to perfect the deceleration point at the end of travel.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX240-10 the Right Cylinder?
Select this 200 mm bore cylinder when your application demands extreme thrust, specifically 15708 N push or 15080 N pull at 0.5 MPa. If your setup only requires moderate force, stepping down to a 160 mm bore yields 10053 N push at 0.5 MPa, which might better suit lighter machinery. The SAIJ200X240-10 is chosen over a fixed SAI model when you need a variable end-stop to accommodate product changeovers or fine-tune a 230-240 mm travel window without swapping out the entire actuator.
Because this is a 240 mm stroke, evaluate your mounting configuration to prevent rod sag and side-load damage, utilizing an external guide for unsupported loads. To achieve a true ISO 15552 replacement match, verify the 200 mm bore, 240 mm stroke, 10 mm adjustment, G3/4 port, and your preferred mounting style from the available SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2. Note that FB, CA, CB, and CR mounts are omitted from this adjustable series. If your process requires the load to be held mechanically without continuous air pressure, consider an AirTAC SAIL locking cylinder or a BSAI clamp-lock instead of relying on this rear 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 SAIJ200AX240-10 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At its maximum rated pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjuster acts as a mechanical stop that allows you to shorten the nominal 240 mm stroke by up to 10 mm, providing a usable travel window of 230-240 mm. It is designed for end-position tuning and deceleration, not for locking the load without live air pressure.
