Hallite | 58-2000 | Seal

Strong and durable double-acting piston seal able to keep friction low. The combined nature of this seal enables the designer to use large clearances and, with the integral bearing rings, to restrict the piston length. The assembly comprises a seal and two L-shaped bearings. The center of the seal is rubber bonded to two ‘U’ section bases of rubberized fabric and is compressed by the housing to obtain an effective low-pressure seal. When the pressure increases, the rubber energizes the ‘U’ section and deforms it to the housing, increasing the sealing area and improving the seal.
