Abstract
A seal assembly for sealing a shaft bearing includes a seal housing, first and second seal rings retained by the seal housing, an annular chamber formed between the first and second seal rings and a connecting channel configured to place the annular chamber in fluid communication with a bearing-housing-side oil space. When the seal assembly is installed on a shaft, the connecting channel is configured to permit a fill-level equalization between the oil space and the annular chamber when the oil space is filled to a first possible fill level (N) and to prevent the fill-level equalization between oil space and annular chamber when the oil space is filled to a second possible fill level (N).
