BA U-Cup

BA (Rod Seals)

Profile BA is the consequence of further development of the lip seal. It combines the advantages of a highly elastic O-ring and the abrasion resistance of a lipseal compound. This special seal is mainly used in the mobile hydraulic industry because of its special feature – the fitted O-ring. The O-ring guarantees the preloading of the seal lips under low pressure or vacuum, this is necessary for the sealing function. The sealing force is largely independent of temperature variations, ant it ensures the necessary preloading even if a certain amount of abrasion takes place. The lop is loaded according to increasing system pressure, transmitted through the pressure-dependent deformation of the O-ring.

The BA U-Cup Offers:

• Unusually high abrasion resistance

• Insusceptible to shock loads

• High resistance to extrusion

• Perfect sealing action in no-load and low temperature conditions

• Suitable for the most difficult working conditions

• Easy installation

Application:

• Working Pressure: = 350 bar

• Working Temperature: -35°C to 80°C (-31°F to 176°F)
