The AirTAC SAI32 Standard Cylinder SAI32BX475S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 475mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAI32X475-S is a double-acting ISO 15552 profile cylinder engineered for precise linear motion. It generates 402 N of push force at 0.5 MPa and features a 475 mm stroke, making it well-suited for intermediate-trroke positioning tasks.
This variant includes a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet for use with CMSE or DMSE sensor switches. It utilizes PT tapered port threads and operates reliably at speeds between 30 and 800 mm/s.

Drives small clamps and pick-and-place mechanisms requiring 402 N of push force over a 475 mm extension.
Actuates sorting arms on packaging lines where a 32 mm bore provides adequate speed and thrust for lightweight cartons.
Extends components from testing stations, utilizing the integrated magnet to confirm full stroke position via DMSE switches.
When sizing this actuator, consider that stepping down is not an option if you need the full 475 mm travel at this force class. If your application requires less extension, a shorter stroke reduces overall envelope size and rod deflection. Because this model spans 475 mm, the unsupported rod is subject to bending under side loads; utilize an external guide rail or a guided cylinder to prevent premature rod-bearing wear.
As a dimensionally interchangeable ISO 15552 unit, this cylinder serves as a direct replacement matching the 32 mm bore, 475 mm stroke, PT port, and standard mounting accessories like LB foot brackets. Note that standard air cushions only decelerate the piston near stroke ends; if the air supply is lost, the rod will drift. Use an external pilot-operated check valve to hold a load safely.
Quick checklist
At 0.5 MPa, the push force is 402 N and the pull force is 345 N. At 0.7 MPa, the push force increases to 563 N.
Yes, the SAI32X475-S is dimensionally interchangeable per ISO 15552. You can drop it into existing 32 mm bore setups using standard FA flange or LB foot mounts.
