Din 3760 Pdf Extra Quality (2025)
Complying with the DIN 3760 standard offers several benefits, including:
This provides structural rigidity to the seal, allowing it to be pressed firmly into the housing bore.
An added to any variant (such as Form AS) indicates the inclusion of an auxiliary dust lip . This secondary lip functions without a garter spring and acts as a mechanical barrier against external dirt, dust, and moisture splash. When using dust lips, filling the internal cavity between the primary and secondary lips with grease minimizes friction during operation. Core Technical Specifications & Operating Limits
: Similar to Form B but includes an additional reinforcing cap. This design offers maximum rigidity and is often used for larger seal sizes or in applications where installation conditions are harsh. din 3760 pdf
DIN 3760 is intended for or low‑pressure applications only. Exceeding the maximum allowable pressure will cause the sealing lip to lift off the shaft, resulting in immediate leakage. For pressurized systems, specially reinforced seals (e.g., Type AS-P or AS-PX) or mechanical seals must be used.
Automotive applications, engine oils, and transmission fluids with extreme-pressure (EP) additives. Critical Installation and Housing Tolerances
Broad temperature extremes, low friction needs; poor dry-running capability. 4. Technical Design Considerations Complying with the DIN 3760 standard offers several
This standard is essential for preventing leakage of lubricants (oil, grease) and ingress of contaminants (dirt, dust, water) in rotating machinery. You will find components built to DIN 3760 in:
DIN 3760 classifies seals based on their construction, primarily distinguishing between the presence of a dust lip (sometimes called a protective lip) and the external construction (metal vs. rubber encased). Types of Design

DIN 3760 is a fundamental German technical standard that specifies the dimensions, materials, and installation requirements for . 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.
The query for reflects the need for more than just a document—it is a search for a foundational engineering standard that governs the reliability of rotating machinery worldwide. From the rubber-coated elasticity of a Type A seal to the brute strength of a Type C reinforced case, DIN 3760 ensures that every dimension, tolerance, and material selection is optimized for performance.
If you need to source or specify these components for a live project, let me know: What is the and shaft speed ? What fluid or chemical is being sealed?
DIN 3760 is a German standard that specifies the dimensions, materials, and requirements for . These seals are primarily used to retain fluids like oil or grease in unpressurized equipment (or equipment with very low differential pressure). Key Components of the Seal:
