About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX300-20
The AirTAC SAIJ32X300-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down to a 280-300 mm window. It delivers 402 Newtons of push force at 0.5 MPa, making it suitable for lighter-duty positioning tasks.
This variant uses a SUS304 stainless steel rod for corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is configured without a magnet for position sensing.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX300-20 Is Used
Machine Setup Changeover
Dial in the exact retract position during product line changeovers without physically swapping the cylinder or bolting on external stopper blocks.
Variable End Stops
Adjust the 280-300 mm travel window on the fly to accommodate slight variations in package sizes or positioning requirements on a handling line.
Light-Duty Positioning
Leverage the 402N push force and SUS304 rod for precise, corrosion-resistant component placement in lighter-duty manufacturing equipment.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX300-20 the Right Cylinder?
Choose this 32 mm bore when you need precise end-position tuning at commissioning without adding external stops, as its 20 mm rear adjuster modifies the retract end of a 300 mm stroke. If your application requires higher force, stepping up to a 40 mm bore provides 628 N of push force at 0.5 MPa. Because the stroke is 300 mm, an external guide is recommended to prevent excessive side-loading on the 12 mm rod. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for true load-holding without pressure, consider an SAIL or BSAI cylinder. This model is dimensionally interchangeable with ISO 15552 cylinders and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ32BX300-20 FAQ
The rear adjuster screw allows you to shorten the nominal 300 mm stroke by up to 20 mm, providing a usable travel window of 280-300 mm. It acts as a mechanical stop to fine-tune the end position and is not a lock.
At 0.5 MPa operating pressure, it provides 402 Newtons of push force and 345 Newtons of pull force. The maximum operating pressure is 1.0 MPa.
