About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX75-75
The AirTAC SAIJ200X75-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. With a 75 mm nominal stroke and a 75 mm adjustment code, it provides a usable travel window of 0-75 mm. This massive 200 mm bore delivers 15708 N of thrust at 0.5 MPa, making it ideal for heavy-duty pressing and positioning tasks.
This unit includes a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel features sensor grooves on both sides. The rear stopper allows you to fine-tune the end position at commissioning without adding external physical stops.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX75-75 Is Used
Heavy-Duty Forming
Dial in the exact 0-75 mm travel window for pressing operations, allowing quick reconfiguration for different material thicknesses without changing the cylinder.
Machine Changeover
Fine-tune the retract end-position during product size changeovers on a packaging line, using the rear stopper to adapt the stroke on the fly.
Variable End Stops
Set precise physical end limits for heavy clamping fixtures, leveraging the 15708 N push force while adjusting the stroke to accommodate varying part dimensions.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX75-75 the Right Cylinder?
Choose this 200 mm bore when you need extreme force—up to 15708 N at 0.5 MPa or 3204 kgf at 1.0 MPa. If your application requires less push force, stepping down to the 160 mm bore yields 10053 N at 0.5 MPa. The adjustable stroke is selected when you need a variable end-stop for product changeovers rather than a fixed-stroke SAI cylinder.
Because the stroke is 75 mm, side-load risks are minimal, but always ensure the load is guided externally. The rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, select an AirTAC SAIL or BSAI cylinder. This model is dimensionally interchangeable with ISO 15552 cylinders. It supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, and operates at 30-500 mm/s.
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 SAIJ200BX75-75 FAQ
At a 0.5 MPa operating pressure, the 200 mm bore provides 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it delivers 3204 kgf.
The rear adjuster screw lets you shorten the 75 mm nominal stroke by up to 75 mm, creating a 0-75 mm usable travel window. It acts as a travel stop for end-position tuning and does not lock the load without live air pressure.
