Abstract
A seal structure comprises a combination of a dynamic seal assembly which is active while a rotary body is rotating and a static seal assembly which is active while the rotary body is not rotating. The dynamic seal assembly includes a seal member mode of low friction material. On the other hand, the static seal assembly has an elastically deformable seal member. A rotary receptacle bore has two different diameter sections. The dynamic seal assembly is designed and sized to be installed in a smaller diameter section of the bore and the static seal assembly is designed and sized to be installed in a larger diameter section. The seal structure is assembled by inserting the dynamic seal between the smaller diameter bore section via the larger diameter section. Subsequently, the static seal is inserted into the larger diameter section.
