About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX200-20S
The AirTAC SAIJ32X200-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 200 mm nominal stroke that can be dialed back by up to 20 mm, yielding a precise 180-200 mm usable travel window for fine-tuning end positions during commissioning. Delivering 402 N of push force at 0.5 MPa, it suits lighter-duty positioning tasks.
This variant features a SUS304 stainless steel rod for corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides. It uses a PT tapered port thread and offers adjustable air cushions at both ends to decelerate the load smoothly.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX200-20S Is Used
Machine Changeover
Dial in the 180-200 mm travel window during product size changeovers to set new end positions without replacing the cylinder.
Assembly Positioning
Fine-tune the retract stop on assembly lines to perfectly seat components using the 402 N push force at 0.5 MPa.
Light Conveyor Sorting
Adjust the stroke on the fly for varying package sizes on a conveyor, relying on the stainless SUS304 rod for durability.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX200-20S the Right Cylinder?
Select this 32 mm bore cylinder when an application requires 402 N push force at 0.5 MPa, stepping down from a 40 mm bore that yields 628 N. Choose this adjustable-stroke SAIJ over a fixed-stroke SAI when a machine requires variable end-stops to accommodate product size changeovers without physically swapping the cylinder or adding external stops. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure; for true fail-safe load holding, consider an AirTAC SAIL or BSAI series instead.
For ISO 15552 replacement matching, this cylinder uses a 32 mm bore, 200 mm stroke, 20 mm adjustment range, PT G1/8 port, and an -S magnet. The mounting interface accepts Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessories. Since the 200 mm stroke is relatively long for a 32 mm bore, ensure external guidance is used to prevent excessive side-loading on the 12 mm rod and M10x1.25 rod thread.
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 SAIJ32BX200-20S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. The maximum rated operating pressure is 1.0 MPa.
The rear adjuster screw allows you to shorten the 200 mm nominal stroke by up to 20 mm, creating a 180-200 mm usable travel window. This stopper only sets the end position; it does not lock the load without continuous air pressure.
