Description
The seal group consists of two identical metal rings and two rubber rings. Its working principle is that a pair of rubber rings form a closed space with the cavity (but not in contact with the shaft) under the support of the metal rings. When the metal rings rotate, The two ground surfaces fit closely and slide relative to each other. On the one hand, they ensure good operation. On the other hand, they effectively isolate dust, water, sludge, etc. from the outside and protect the internal lubricating grease from leaking.
At Decent Machinery, we provide duo cone seals made of by using high standards in the industry. The main component of the metal ring is FC15Cr3Mo. Its hardness after heat treatment generally reaches HRC 65-72.
