About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX200-20
The AirTAC SAIJ32X200-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel within a 180 to 200 mm window. Delivering 402 N of push force at 0.5 MPa, it fits light-duty positioning tasks perfectly. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This variant uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The rear adjuster acts purely as a mechanical stop to trim the retract end-position during commissioning. It does not lock or hold the load without continuous air pressure; for fail-safe holding, consider the SAIL or BSAI series.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX200-20 Is Used
Product Changeover
Dial in the 180-200 mm travel window during machine setup to accommodate different product sizes without replacing the entire cylinder.
End-Position Tuning
Fine-tune the retract stop at commissioning to resolve mechanical tolerances and achieve precise end-of-stroke positioning.
Light-Duty Positioning
Leverage the 402 N push force for compact assembly tasks requiring exact physical stops rather than full fixed strokes.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX200-20 the Right Cylinder?
Choose this 32 mm bore when an application requires precise variable end-stops without swapping the cylinder or adding external stops. If your setup needs less force, dropping down a bore size is an option, but stepping up to a 40 mm bore yields 628 N of push force at 0.5 MPa for heavier loads. The integrated rear screw allows rapid product changeovers.
Because this is a 200 mm stroke, the 12 mm rod and M10x1.25 thread handle moderate side loads, but long unsupported strokes still require an external guide. To match this ISO 15552 replacement exactly, specify the 32 mm bore, 200 mm stroke, 20 mm adjustment, PT port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and no magnet.
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 SAIJ32BX200-20 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
The rear adjuster screw lets you shorten the nominal 200 mm stroke by up to 20 mm, creating a 180-200 mm usable travel window. This mechanical stop only sets the end position; it does not lock the load without live air pressure.
