DIN 3760 is a fundamental German technical standard that specifies the dimensions, materials, and installation requirements for rotary shaft lip seals. These seals, commonly known as oil seals or Simmerrings, are designed to retain fluids like oil or grease in equipment with rotating shafts while preventing the ingress of dirt.
Shaft Tolerance: Typically requires an ISO h11 tolerance for the shaft diameter. din 3760 pdf
DIN 3760: Rotary shaft lip seals with dust lip is a German industrial standard (Deutsches Institut für Normung) that defines the dimensions, tolerances, materials, and performance requirements for radial shaft seals featuring an additional dust lip. These seals are commonly used in: DIN 3760 is a fundamental German technical standard
(the official DIN distributor), many seal manufacturers provide summarized "technical catalogs" or data sheets in PDF format that contain the most vital dimensions and material specs for free. material compatibility chart from the DIN 3760 standard? Reliable sealing performance : Effective sealing of rotating
Shaft Requirements: Hardness of at least 45 HRC is required (increasing to 60 HRC at higher speeds) with a surface roughness of Racap R sub a 0.2 to 0.8 µm. 2. Standard Design Forms
NBR (Nitrile): The standard "workhorse" material. Good for oils and greases.
