About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX200-50S
The AirTAC SAIJ32X200-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 402N of push force at 0.5MPa and features a 150-200mm usable travel window, letting you trim the nominal 200mm stroke by up to 50mm during commissioning without adding external stops.
This SKU includes a SUS420J2 stainless steel rod and a magnetic piston for CMSE or DMSE sensors. The rear adjuster acts purely as a travel stop for end-position tuning, not a lock, so live air is required to hold the load. It uses the standard SAIJ mounting set of Basic, FA, LB, TC, FTC, TCM1 and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX200-50S Is Used
End-Position Tuning
Dial in the exact retract distance within the 150-200mm window during machine commissioning without swapping hardware.
Product Changeover
Quickly adapt the cylinder stroke for different product sizes on a packaging line by rotating the rear adjuster.
Variable End Stops
Set precise physical stops for light-duty assembly tasks using the 402N force output at 0.5MPa.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX200-50S the Right Cylinder?
Choose this adjustable-stroke model when a machine setup requires variable end stops or frequent product changeovers, avoiding the need to swap fixed-stroke SAI cylinders. If your application needs less push force, stepping down is not an option from this 32mm bore, but stepping up to a 40mm bore yields 628N at 0.5MPa for heavier payloads.
For an exact ISO 15552 replacement, match the 32mm bore, 200mm nominal stroke, 50mm adjustment range, PT tapered port, and the -S magnet requirement. Because the stroke is 200mm, ensure external guiding for any side loads, as the 12mm rod and M10x1.25 thread need support on longer travels.
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 SAIJ32AX200-50S FAQ
The rear adjuster is a mechanical stop that lets you shorten the effective travel from 200mm down to 150mm. It sets the end position but does not lock the load without live air pressure.
At 0.5MPa it provides 402N of push force and 345N of pull force. At the maximum operating pressure of 1.0MPa, the push force reaches 80kgf.
