Introduction
Rotary shaft lip seals are used to seal liquid on the relatively low pressure device. The most typical is the axis of rotation of the stationary chamber,
However, in some cases, the shaft is stationary and rotating cavity.
Typically, there is a dynamic seal designed interference fit between the shaft and the flexible seal member.
Similarly, between the outer and inner hole seal cavity interference fit can seal liquid and prevents static leakage.
To avoid damage, before installation and during installation, it is necessary to be careful of all seal storage, handling and safety
Equipment, improper storage, handling and installation can affect the seal life.
