About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX150-40S
The AirTAC SAIJ200X150-40-S is a double-acting ISO 15552 profile cylinder engineered for high-force applications requiring exact end-position tuning. Equipped with a 200mm bore, it delivers up to 15708N of push force at 0.5 MPa and 15080N of pull force. The integrated rear adjusting screw allows you to trim the 150mm nominal stroke back by up to 40mm, providing a usable travel window of 110-150mm for precise commissioning without external stops. This unit includes a magnet for position sensing and features a SUS420J2 stainless steel rod for enhanced corrosion resistance.
Unlike fixed-stroke alternatives, this adjustable design lets you dial in the retract end on the fly during product changeovers. The rear screw acts purely as a mechanical stop and works in tandem with the standard air cushions at both ends to decelerate the load. It does not lock or hold the load without continuous air pressure; for fail-safe load holding, consider the SAIL or BSAI series. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX150-40S Is Used
Heavy Press Tuning
Dial in the exact 110-150mm travel window during heavy press commissioning to accommodate material thickness variations without swapping cylinders.
Product Changeover Stops
Adjust the retract stopper on the fly when shifting a high-force conveyor line between different product sizes and package dimensions.
Large Assembly Positioning
Position heavy structural components accurately by fine-tuning the end-of-stroke stop, leveraging the 15708N push force for secure placement.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX150-40S the Right Cylinder?
Selecting this 200mm bore cylinder is appropriate when your application demands very high thrust (up to 3204 kgf at 1.0 MPa) and variable end-stops. If your force requirements are lower, stepping down to a 160mm bore yields 9425N of pull force at 0.5 MPa, which may offer a more compact and efficient solution. Conversely, if you need less force, a 125mm bore provides 5734N of pull. Choose the SAIJ adjustable-stroke format over the fixed SAI when you need fine-tuning flexibility at machine setup or when accommodating varying product sizes on the same line.
For ISO 15552 replacement matching, verify the 200mm bore, 150mm nominal stroke, 40mm adjustment range, PT tapered port threads, and the -S magnet option. The standard speed range for this bore is 30-500 mm/s. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. The robust 40mm rod and M36x2 thread handle significant side loads, but even with this heavy-duty rod, any long unsupported stroke requires an external guide to prevent premature wear.

- ✓ 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 SAIJ200AX150-40S FAQ
At 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At the maximum operating pressure of 1.0 MPa, it can deliver up to 3204 kgf.
The rear adjusting screw allows you to shorten the effective stroke from its 150mm nominal length by up to 40mm, creating a usable travel window of 110-150mm. The adjuster acts as a mechanical stop to set the end position and does not function as a lock or brake to hold the load without air pressure.
