Hebei Hankai dust wiper seal




The hub axle seal's primary function is to keep the axle lubricated. The lubricant, often a type of grease or oil, is crucial for reducing friction between moving parts. Without proper lubrication, the components can suffer from overheating and excessive wear, potentially leading to significant damage and costly repairs. Additionally, the seal prevents water and dirt from entering the axle assembly, which can cause rust and corrosion, further jeopardizing the integrity of the axle.



Rubber tapes are generally non-adhesive, and are either equipped with a liner or are linerless. Stretched and overlapped layers will fuse or bond together to form an effective electrical insulation and moisture barrier. For low-voltage (1000V or less) applications, rubber tapes should be stretched during wrapping so that tape width is reduced to approximately 75%. For high- and medium-voltage applications — where the electrical stresses are high (e.g. connector areas, lug areas, and cable shield cut-back areas) — tape should be stretched just short of its breaking point.
