Contact SupplierThe felt is a simple and adequate seal with grease lubrication at peripheral speeds up to 4 ms. It can be used at temperatures of -40 to +100 degree C. Felt seal is contact seal rubbing on shaft surface. It can also be used at higher speeds but a small gap will then generally be formed between the felt and the shaft, so that the sealing action becomes that of a non-rubbing gap- type seal. Plummer Block housing of series SNA, SNH and SNL are available with split Felt Seals consisting of oiled felt incorporated in the two halves of an aluminum alloy ring. Such seals are designated as TC or TSNA 500C & TSNA 600C. There is an external groove in alloy ring halves where O- section rubber cord is inserted while fitting the seal halves into the bearing housing. The O-section cords provide an effective contact between the housing and the alloy ring in addition to preventing the ring rotation in the housing.
