Truefit Engineering Co. Ltd. Manufactures Felt Seal with Grease Lubrication. Truefit Engineering Co. Ltd. Is an ISO 9001:2000 certified company. Felt Seal with Grease Lubrication is normally used with bearing housing of variety SN, PDN, TVN, flanged housing, SD500, SD600, SD30 series. Felt Seal with Grease Lubrication is also used for SDG type along with labyrinth seal. It can be used at temperatures of -40 to +100 degree C. This 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. Felt seal can be selected for external conditions with dust, sand, grit, sharp objects, clippings, splinters and sunshine, but it is less suitable with splashing fluids.
