The World Cat Federation has also adopted this classification, treating the color point Short hair as a distinct breed. Many Siamese cats from Thailand had a kink
Radial shaft seal point contact with the shaft. The point contact is formed by two angles, with the air side angle usually less than the oil side angle. Depending on the seal type these two angles are varied to create a pressure distribution at the seal contact point which has a steeper slope on the oil side of the seal. The shallower the slope on the oil side of the seal the wetter the seal will run. The spring is positioned such that axially the centerline of the spring is biased to the air side of the lip contact point. In order to
