HS Code: 8487900000 Product Description Description:DO Type Floating seal is used for crawler-type machine mounted on the bottom roller demands to functions to prevent inside oil from leaking and to prevent other materials invading.Detail Description:DO Type Floating seal canbe installed on idler wheel/final drive/carrier roller/truck roller of excavator,it prevents inside oil leaking out and outside other material from invading.Because floating seal is made up of two parts,one is stationary side,the other is rotationary side,so compression ratio is very important for it,the excellent design contributes to improve span life of floating seal.How to install floating seal?When the floating seal with O-type rubber ring is placed into housing bore, install the rubber gasket evenly and straight without distortion or damage. Before the two pairs of floating seal placed into the collar are assembled, make sure that the sealing face of the two metal rings are clean , and apply the lubricating oil used in this machine on the sealing face to ensure that the sealing face has film lubrication, so as to avoid the dry grinding without oil after installation and instant damage. based on the past experience, as for floating seal using O-type rubber ring, a little lubricating oil will be spilled out from the mating face of floating seal ring external diameter during about one-hour movement test-run period when it is just installed for commissioning, which is normal phenomenon instead of oil leakage.
