About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX145-50S
The AirTAC SAIJ200X145-50-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 95 to 145 mm. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa, making it suitable for heavy-duty industrial operations. The barrel is extruded aluminum with sensor grooves on both sides, distinct from tie-rod designs.
This specific SKU features a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and carries the -S magnet option for use with AirTAC CMSE reed and DMSE electronic sensors. The rear adjuster acts purely as a travel stop to fine-tune end positions without adding external stops, but it does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX145-50S Is Used
Product Size Changeover
Leverage the 95-145 mm travel window to rapidly adapt heavy press machinery for varying product lengths during line changeovers.
Heavy Press Tuning
Fine-tune the exact end-of-stroke position during commissioning to ensure precise 15708 N clamping force without mechanical spacers.
High-Force Positioning
Shift large workpieces on a conveyor using the 40 mm SUS420J2 stainless rod, relying on the adjustable stop for repeatable endpoints.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX145-50S the Right Cylinder?
Select this 200 mm bore cylinder when an application requires up to 15708 N of push force at 0.5 MPa, stepping up from a 160 mm bore that yields 10053 N. The 50 mm adjustment range is ideal for product changeover or commissioning fine-tuning, allowing you to dial in the exact end-stop without swapping the cylinder for a fixed-stroke SAI model. Because the stroke is 145 mm, an external guide is recommended for the large 40 mm rod if handling heavy side loads.
For load-holding without continuous air pressure, this cylinder's adjuster and air cushions will not function as a brake; you must use an external rod lock or pilot-operated check valve, or select the SAIL or BSAI series. As a dimensionally interchangeable ISO 15552 cylinder, it uses a PT G3/4 port, features a 40 mm rod with M36x2 thread, operates at 30-500 mm/s, and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mountings (omitting FB, CA, CB, and CR).

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 SAIJ200AX145-50S FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It can reach a maximum push force of 28274 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the nominal 145 mm stroke by up to 50 mm, creating a usable travel window of 95 to 145 mm. This stopper fine-tunes the end position but does not lock or hold the load without live air pressure.
