Special floating oil seal in tunnel shield machine

2020-01-08 11:52:06
Floating oil seal is a combination of metal floating ring and rubber seal ring. It is a common accessory. The most common seal materials for shield machine repair kits are PTFE or silicone rubber.Depending on the model of the shield machine repair kit, saddle-shaped cross-sections and L-shaped cross-sections can be designed, and the matched rubber seal ring is a highly practical sealing element.


Floating oil sealare mainly used in harsh, low-speed, heavy-duty working environments, such as bulldozers, tunnel shields, conveyors, mixers, excavators, mining machinery, agricultural machinery, and heavy trucks.


The floating oil sealhas the characteristics of wear resistance, impact resistance, simple and reliable design structure, and automatic compensation for wear. At the same time, it can effectively compensate the eccentricity of the shaft and the radial runout under dynamic work.
