About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX75-20S
The AirTAC SAIJ200X75-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 55 to 75 mm. It delivers exceptional power, generating 21991 N of push force at 0.7 MPa, making it suitable for heavy-duty operations requiring precise end-position tuning. The barrel is extruded aluminum, not a tie-rod design, ensuring a rigid yet lightweight structure.
This specific SKU features a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered ports sized at G3/4. The integrated magnet (-S) enables seamless position detection with AirTAC CMSE reed and DMSE solid-state sensors. The rear adjuster functions solely as a mechanical stop to dial in the retract position during commissioning; it does not lock or hold the load without continuous air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX75-20S Is Used
Machine Setup & Changeover
Dial in the exact retract distance from 55 to 75 mm during line changeovers without physically swapping cylinders or bolting on external mechanical stops.
Variable End-Stop Positioning
Fine-tune the end-of-stroke position on heavy machinery to compensate for mechanical wear or tooling variations, ensuring precise heavy-duty positioning.
Product-Size Adjustments
Quickly adapt the stroke window for different sized products on the same production line, leveraging the 21991 N thrust for massive actuation tasks.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX75-20S the Right Cylinder?
Choose this 200 mm bore when an application demands up to 21991 N of thrust at 0.7 MPa and requires on-the-fly end-stop calibration without adding external stops. If your force requirements are lower, stepping down to a 160 mm bore yields 14074 N at 0.5 MPa, while the adjustable 55-75 mm window here is perfect for product changeovers. For any load-holding requirements without live air pressure, this cylinder is insufficient; consider an AirTAC SAIL or BSAI series instead.
As a dimensionally interchangeable ISO 15552 cylinder, matching replacements requires the 200 mm bore, 75 mm nominal stroke, 20 mm adjustment range, G3/4 PT ports, and the -S magnet. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets. Although the 40 mm rod and M36x2 thread provide high rigidity, long unsupported strokes still necessitate an external guide.
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 SAIJ200BX75-20S FAQ
At an operating pressure of 0.7 MPa, this 200 mm bore cylinder generates 21991 N of push force and 15080 N of pull force. It can deliver a maximum push force of 28274 N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that trims the effective travel, creating a 55 to 75 mm usable stroke window from the 75 mm nominal length. It allows precise end-position tuning at commissioning but does not lock or hold the load without live air pressure.
