White Roller Stator Motor – 505350W3122AAAAA is a mid-to-high displacement RE 505 Series wheel drive motor where the tapered shaft locks directly into the wheel hub. This self-centering fit between the shaft and the hub keeps the drive connection secure through the load shifts, impacts, and sustained traction demands of heavy mobile propel work. On a 4-hole wheel mount with 348 cm³/rev displacement and 8,150 in-lbs continuous torque, it belongs on agricultural equipment, compact construction machines, and material handling vehicles running slow and pulling hard. Impro Fluidtek builds these motors on the original White Drive Products patents, acquired directly from Danfoss in 2022. This motor also replaces 500350W3122ZAAAA.
