About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX450-10
The AirTAC SAIJ200X450-10 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications, featuring a 450 mm stroke that can be precisely dialed back by up to 10 mm. This yields a 440-450 mm usable travel window, allowing you to fine-tune the retract end position at commissioning without adding external stops. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa, making it ideal for high-force operations.
This unit is built with an SUS420J2 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX450-10 Is Used
Heavy Press Tuning
Dial in the exact 440-450 mm retract position during machine commissioning to ensure perfect pressing force without swapping cylinders.
Product Size Changeover
Quickly adjust the rear stop by up to 10 mm to accommodate slight variations in product dimensions on a high-force assembly line.
Large Tooling Alignment
Fine-tune the end-stop position for heavy industrial tooling, leveraging the 15708 N push force at 0.5 MPa for robust alignment.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX450-10 the Right Cylinder?
Select this 200 mm bore cylinder when you need extreme force—up to 21991 N push at 0.7 MPa—and exact end-position control. If your application requires slightly less force, stepping down to a 160 mm bore yields 10053 N push at 0.5 MPa. Choose the SAIJ adjustable-stroke design over a fixed SAI cylinder when you need variable end-stops for product changeovers. For load-holding without live air, integrate an external rod lock or use an AirTAC SAIL or BSAI cylinder, as the SAIJ adjuster is not a lock.
Because this cylinder features a 450 mm stroke, the 40 mm rod and M36x2 thread provide substantial support, but an external guide is recommended to manage side loads on long strokes. This model meets ISO 15552 dimensional interchangeability standards. Confirm the exact PT porting, mounting style, and that no magnet is specified for your setup.
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 SAIJ200AX450-10 FAQ
At 0.5 MPa, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
The rear adjuster screw allows you to shorten the 450 mm nominal stroke by up to 10 mm, creating a 440-450 mm travel window. It functions as a stop for end-position tuning and is not a locking mechanism.
