Um, no. SR never owned SunTour.
According to Frank Berto (see his
"Sunset for Suntour" article), SR was bought out by Mori Industries (a Japanese steel tubing company) in 1989. In 1990, Mori bought out Madea SunTour, combining the two entities shortly thereafter. The resulting company was called SR SunTour (likely to make use of both SR's and SunTour's name recognition).
The bottom bracket under discussion in the Amazon link above was apparently made after Mori combined SR and SunTour. Given SunTour's extensive expertise with bottom brackets, I'd guess it was made by the old SunTour division - but that's only a guess.
