Mechanical Face Seals for Heavy-Duty Rotational Applications\u00a0<\/span><\/h1>\r\nOur Mechanical Face Seals, also known as floating seals, face seals, Duo-Cone\u2122 seals, lifetime seals, heavy-duty seals, or toric seals, are widely used in heavy-duty rotational applications, particularly in harsh and abrasive environments, such as dirt, dust, mud, water, and aggressive fluids. These seals are designed to withstand severe wear and resist abrasive and corrosive media. Mechanical Face Seals are reliable sealing components that promote uninterrupted operations, prolong maintenance intervals, and contribute to the overall longevity of machinery and equipment.\r\n\r\nMechanical face seals consist of two half sets, each with a seal ring and an elastomer loader. The other seal ring remains static in its house while the other rotates in its counterface. They are available in DO and DF profiles.[\/vc_column_text][\/vc_column][\/vc_row][vc_row sm=”10″ smb=”10″][vc_column width=”2\/3″ offset=”vc_col-lg-7″][web3_vc_list_icon_texts h=”h2″ sm=”20″ md=”20″ lg=”20″ title=”Mechanical Face Seals Advantages” items=”%5B%7B%22icon_name%22%3A%22icon_Check_Circle%22%2C%22title%22%3A%22Cost-effective%22%7D%2C%7B%22icon_name%22%3A%22icon_Check_Circle%22%2C%22title%22%3A%22Simple%2C%20reliable%20design%22%7D%2C%7B%22icon_name%22%3A%22icon_Check_Circle%22%2C%22title%22%3A%22Increased%20operational%20lifespan%22%7D%2C%7B%22icon_name%22%3A%22icon_Check_Circle%22%2C%22title%22%3A%22Ease%20of%20installation%20and%20replacement%22%7D%2C%7B%22icon_name%22%3A%22icon_Check_Circle%22%2C%22title%22%3A%22Excellent%20at%20retaining%20lubricants%20%22%7D%2C%7B%22icon_name%22%3A%22icon_Check_Circle%22%2C%22title%22%3A%22Outstanding%20at%20preventing%20contaminants%20from%20entering%22%7D%2C%7B%22icon_name%22%3A%22icon_Check_Circle%22%2C%22title%22%3A%22Self-centering%20to%20compensate%20for%20shaft%20eccentricity%20and%20mis%20alignment%22%7D%2C%7B%22icon_name%22%3A%22icon_Check_Circle%22%2C%22title%22%3A%22Exceptional%20resistance%20to%20severe%20wear%2C%20abrasion%2C%20and%20corrosive%20media%22%7D%5D”][\/web3_vc_list_icon_texts][\/vc_column][\/vc_row][vc_row sm=”20″ smb=”20″][vc_column offset=”vc_col-lg-7″][vc_column_text css=””]\r\n

Applications<\/h2>\r\nMechanical Face Seals are commonly found in axles, final drives, idlers, transmissions, conveyors, pumps, rollers, tunnel boring cutters, undercarriages, wet braking systems, gearboxes, mixers, stirrers, and mobile track systems. These seals are commonly used in mining, agriculture, and construction in the following machinery and equipment, including but not limited to:\r\n\r\n\r\n\r\n\r\n\r\n\r\n

    Profiles<\/h2>\r\nWe offer two types of Mechanical Face Seal profiles: DO Type and DF Type.\r\n\r\nDO type is the most common type that employs an O-ring made of elastomer material for the secondary seal. The DO profile requires less radial space within the application. It delivers excellent stability in the housing prior to final assembly and excellent end-play capability.\r\n\r\nDF type features a diamond or trapezoidal elastomer ring as a secondary seal. The DF profile requires less axial space within the application and fits into a square bore housing cavity, which reduces machining time. No assembly tool or lubricant is required during installation.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][web3_vc_db_profiles sm=”” md=”” lg=””][\/web3_vc_db_profiles][\/vc_column][\/vc_row][vc_row sm=”50″ smb=”10″][vc_column offset=”vc_col-lg-7″][vc_column_text css=””]\r\n

    Materials<\/h2>\r\nOur Mechanical Face Seals metal materials are manufactured from alloy cast iron or forged steel. The elastomer ring material is commonly nitrile, but other materials are available, including hydrogenated nitrile, silicone, and fluoroelastomer.[\/vc_column_text][\/vc_column][\/vc_row][vc_row sm=”10″ smb=”50″][vc_column offset=”vc_col-lg-7″][vc_column_text css=”.vc_custom_1776189126726{margin-top: 10px !important;}”]\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n
