Din 3760 Pdf -

DIN 3760 is a German standard that defines the requirements for radial lip seals, also known as radial shaft seals. The standard, titled "Radial shaft seals - Design, dimensions, testing" (in German: "Radial-Wellendichtringe - Konstruktion, Maße, Prüfung"), provides detailed specifications for the design, dimensions, materials, and testing of radial lip seals.

Selecting the right material is crucial for the longevity of the seal, based on temperature and chemical resistance.

: Manufacturers like Tameson and Elastotechnic provide free dimension tables and material data sheets based on the standard.

| Feature | | Type B | Type C | | :--- | :--- | :--- | :--- | | Outer Diameter (OD) | Rubber-covered (Fully coated in elastomer) | Bare metal case (Steel) | Metal case with an additional reinforcing cap | | Primary Function | General-purpose sealing | High extraction force resistance | High rigidity for rough conditions | | Key Advantage | Excellent static sealing in the housing bore, tolerates slight bore imperfections | Higher mechanical strength; resistant to twisting during installation | Superior stability for very large diameters and high-pressure assembly errors | | Dust Lip Option | Type AS (A + Staublippe/dust lip) | Type BS (B + dust lip) | Type CS (C + dust lip) | din 3760 pdf

features a smooth outer diameter (OD) without a dust lip. It is the standard single-lipped seal suitable for general applications. DIN 3760 Type AS is identical to Type A but has an additional dust lip . This extra lip acts as a scraper to prevent external dirt from reaching the main sealing lip.

Rotary shaft seals are critical components in mechanical engineering. They prevent lubricant leakage and protect machinery from external contamination. The German Institute for Standardization established the standard to regulate the dimensions, materials, and testing procedures for these essential components.

Must be rounded and free of burrs to prevent damaging the seal lip during assembly. Housing Bore Requirements Tolerance: Typically machined to an H8 tolerance zone. Surface Roughness: for rubber OD; for metal OD. Why Engineers Download the DIN 3760 PDF : Manufacturers like Tameson and Elastotechnic provide free

The housing bore must be manufactured to an H8 tolerance class. Surface Roughness: For Type A (rubber OD), a roughness of µm is acceptable. For Type B (metal OD), a finer finish of µm is required. Size Chart Guide

: The shaft should have a lead-in chamfer to avoid tearing the seal.

Whether you are an engineer designing a gearbox or a maintenance professional replacing a leaking seal, understanding this standard is critical for preventing fluid loss and protecting machinery from contaminants. What is DIN 3760?
