About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX200-50
The AirTAC SAIJ32X200-50 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 150 to 200 mm, allowing you to dial back the nominal 200 mm stroke by up to 50 mm during commissioning. Delivering 402 N of push force at 0.5 MPa, it suits lighter-duty tasks requiring exact end-position tuning.
The adjuster functions strictly as a mechanical stop for deceleration and does not lock or hold the load without live air pressure. This extruded aluminum barrel unit omits tie-rod construction and uses a SUS304 stainless steel rod for superior corrosion resistance. Its reduced mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX200-50 Is Used
Machine Setup Changeover
Fine-tune the 150 to 200 mm travel window during machine setup to accommodate new product sizes without physically swapping cylinders.
End-Stop Calibration
Use the 50 mm rear mechanical stop to precisely dial in retract positions, avoiding the need to bolt on external stops.
Light-Duty Positioning
Leverage the 402 N push force for light conveying tasks where exact end-of-stroke placement is critical.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX200-50 the Right Cylinder?
Choose this 32 mm bore when 402 N of thrust at 0.5 MPa is sufficient, or step up to the 40 mm bore if you need 628 N. The 50 mm adjustment range is perfect for product changeovers on a line, letting you set variable end-stops without swapping the cylinder or adding external stops. For true load-holding without continuous air pressure, use an SAIL or BSAI cylinder instead.
When replacing an ISO 15552 cylinder, match the 32 mm bore, 200 mm stroke, PT tapered port, and the required mounting accessory. Because the stroke is 200 mm, ensure external guiding is used if side loads are present.
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 Adjustable Cylinder SAIJ32 SAIJ32BX200-50 FAQ
At 0.5 MPa operating pressure, the 32 mm bore provides 402 N of push force and 345 N of pull force. It can deliver up to 724 N at 0.9 MPa.
The rear adjuster lets you shorten the 200 mm nominal stroke by up to 50 mm, creating a 150 to 200 mm usable travel window. It acts as a stop and does not hold the load without live air.
