A split oil seal is usually not made from a single material. It is a composite assembly:<\/p>\n\n\n\n

Sealing body: This is the core functional part that provides sealing. The most commonly used material is polyurethane (PU\/TPU). Nitrile rubber (NBR) and fluoroelastomer (FKM) are also widely used. Polyurethane is particularly popular in split oil seals because of its excellent wear resistance and resilience.<\/p>\n\n\n\n

Split joint \/ connecting block: This is a distinctive feature of split oil seals. It is typically made of reinforced PTFE (polytetrafluoroethylene) or a special polymer composite. Its function is to ensure that the cut ends close tightly after the seal is reassembled, preventing leakage through the split.<\/p>\n\n\n\n

Carcass and spring (internal structure): To maintain shape and provide continuous sealing force, the seal usually contains a metal carcass (such as carbon steel) and a stainless steel spring (commonly V-shaped or Z-shaped).<\/p>\n\n\n\n

Main Manufacturing and Reference Standards<\/h2>\n\n\n\n

As an industrial sealing component, split oil seals are generally manufactured and selected with reference to the following standards:<\/p>\n\n\n\n

Basic dimensions and tolerances: GB\/T 28413-2012, Sealing elements \u2014 Reciprocating seals for hydraulic cylinders \u2014 Groove dimensions and tolerances, is a commonly referenced national standard. It specifies installation groove dimensions and tolerances.<\/p>\n\n\n\n

Product performance and inspection: In industrial procurement, standards such as GB\/T 13871.1, covering rotary shaft lip-type seals incorporating elastomeric sealing elements, are also referenced for physical properties and media resistance.<\/p>\n\n\n\n

Industry and application standards: In specific industries such as coal mining and metallurgy, industry standards such as the MT\/T series (e.g., MT\/T 1164) may be applied to seals used in hydraulic supports and similar equipment, with more specific requirements.<\/p>\n\n\n\n

Split Oil Seal Structural Design Features<\/h2>\n\n\n\n

In addition to materials, the design of split oil seal offers important advantages:<\/p>\n\n\n\n

Split configuration: The most notable feature is the single-split or double-split design, together with a dedicated locking structure. This allows fast installation or replacement without dismantling the equipment.<\/p>\n\n\n\n

Multi-lip design: Split oil seals usually have a primary sealing lip and an auxiliary dust lip. This helps prevent internal media leakage while blocking external dust and contaminants.<\/p>\n\n\n\n

In summary, the performance of a split oil seal is the result of its material formulation, structural design, and manufacturing accuracy. When selecting a seal, the material and standard should be matched to the specific operating temperature, media, and shaft speed.<\/p>\n\n\n\n
