About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-30
The AirTAC SAIJ32X210-30 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 180-210 mm window. Delivering 402 Newtons of pull force at 0.5 MPa, it suits light-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides, though this specific configuration omits the magnet for solid-state sensing.
This variant uses a SUS304 stainless steel piston rod for corrosion resistance and a PT tapered port thread. The rear adjuster acts purely as a mechanical stop to dial in the end position during commissioning; it does not lock the load. For position holding without live air pressure, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-30 Is Used
Machine Changeover
Dial in the 180-210 mm travel window during product size changes without physically replacing the cylinder or adding external mechanical stops.
Light-Duty Positioning
Leverage the 402N pull force at 0.5 MPa for precise end-of-stroke tuning on small actuators and lightweight handling assemblies.
Assembly Line Setup
Fine-tune the rear stop during initial commissioning to perfect the end position, ensuring accurate placement of small components.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX210-30 the Right Cylinder?
Choose this 32 mm bore when your application requires around 402N of pull force at 0.5 MPa; stepping up to a 40 mm bore increases that to 528N if your load demands more push. An adjustable stroke is selected over a fixed SAI when you need variable end-stops for product changeovers without swapping cylinders. To match this exact ISO 15552 replacement, specify 32 mm bore, 210 mm stroke, 30 mm adjustment, PT port, and no magnet.
Because the 210 mm stroke is relatively long for a 32 mm rod, it is susceptible to side-loading; always use an external guide to prevent rod binding. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.
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 SAIJ32BX210-30 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 Newtons of pull force and 402 Newtons of push force. At the maximum 1.0 MPa, it delivers up to 82 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the nominal 210 mm stroke by up to 30 mm, creating a usable travel window of 180-210 mm. It only sets the end position and does not hold the load without live air.
