About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX55-10
The AirTAC SAIJ32X55-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the travel window from 45 to 55 mm during commissioning. Delivering 402 N of push force at 0.5 MPa, it uses a PT G1/8 port and a 12 mm rod. This configuration includes a SUS304 stainless steel rod for superior corrosion resistance in harsh environments.
The extruded aluminum barrel provides standard sensor grooves on both sides for adding CMSE or DMSE switches. The rear adjustment screw acts purely as a mechanical stop to set the retract end-position and does not hold the load without live air pressure. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB and rear pivot styles.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX55-10 Is Used
Product Changeover Tuning
Quickly dial in the 45-55 mm travel window during machine changeovers to accommodate slightly different product sizes without replacing the cylinder.
Corrosive Environment Assembly
Leverage the SUS304 stainless steel rod for small parts assembly in washdown or chemical exposure areas requiring precise end-stop positioning.
End-Stop Calibration
Use the rear mechanical stopper to precisely set the retract end-position during initial machine commissioning, avoiding the need for external shims.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX55-10 the Right Cylinder?
Choose this 32 mm bore when you need 402 N of push force at 0.5 MPa and require precise end-position tuning without swapping cylinders or adding external stops. If your application requires less force, stepping down to a 40 mm bore yields 628 N, but the 32 mm bore offers a more compact footprint. The PT G1/8 port and 12 mm rod thread are standard for this bore size.
Because the SAIJ32X55-10 features a SUS304 stainless steel rod, it is ideal for environments where moisture or corrosive elements are present. Remember that the rear adjuster is a travel stop, not a locking device; for load-holding without live air pressure, consider the SAIL or BSAI series. This profile cylinder is dimensionally interchangeable per ISO 15552.

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 SAIJ32BX55-10 FAQ
At an operating pressure of 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum pressure of 1.0 MPa, it delivers up to 82 kgf.
The nominal stroke is 55 mm, but the external rear adjusting screw allows you to shorten the effective travel by up to 10 mm. This creates a usable adjustable stroke window of 45 to 55 mm to fine-tune the end position without external stops.
