About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX75-40S
The AirTAC SAIJ200X75-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 35-75 mm from its 75 mm nominal stroke. Built to deliver immense thrust, it outputs 15708 N of push force and 15080 N of pull force at 0.5 MPa, scaling up to a maximum push of 28274 N at 0.9 MPa. This model features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing.
Because the rear adjuster acts purely as a mechanical stop to fine-tune the end position, it does not lock the load or hold position without live air pressure. The extruded aluminum barrel includes sensor grooves on both sides, and the PT tapered ports match the G3/4 standard for this bore size. Operating speed spans 30-500 mm/s, and the mounting options cover Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX75-40S Is Used
Heavy Pressing
Dial in the exact 35-75 mm travel window during machine setup to ensure perfect contact force for heavy stamping and forming tasks.
Product Changeover
Quickly adjust the retract end-position stop on the line when switching between product sizes without changing the cylinder hardware.
Beast Mode Clamping
Leverage 28274 N of push force at 0.9 MPa to secure massive workpieces, using the rear screw to set the precise clamping depth.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX75-40S the Right Cylinder?
Choose this 200 mm bore when 160 mm (10053 N push at 0.5 MPa) is insufficient for heavy pressing or clamping. The adjustable stroke is ideal for product changeovers, letting you dial in the exact end-stop without swapping the cylinder or adding external stops. For any load-holding requirements without live air, this cylinder is not a lock; you must integrate an external rod lock or pilot-operated check valve, or select the SAIL or BSAI series.
When replacing an ISO 15552 cylinder, match the 200 mm bore, 75 mm stroke, 40 mm adjustment, G3/4 PT ports, and the -S magnet. Although the 40 mm rod and M36x2 thread handle high side loads, long unsupported strokes of 300 mm or more require an external guide rail to prevent rod binding.

- ✓ 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 SAIJ200BX75-40S FAQ
At 0.5 MPa it provides 15708 N push and 15080 N pull force. At 0.9 MPa, the push force increases to 28274 N.
The rear adjuster screw lets you mechanically shorten the 75 mm nominal stroke, providing a usable travel window between 35 and 75 mm for fine-tuning at commissioning.
