Din - 3760 Pdf

The standard applies to seals used on rotating shafts under conditions of or low pressure difference (generally up to 0.05 MPa). It is intended for applications in general mechanical engineering , distinguishing it from other standards like DIN 3761, which covers seals specifically for the automotive industry.

The standard defines several basic construction types based on the outer diameter (OD) and lip configuration: Rotary shaft lip seals DIN 3760 | norelem

The standard specifies the design, dimensions, materials, and testing requirements for radial shaft seals to ensure reliable sealing performance and long-term durability.

are the most common variants (with/without dust lip). NBR is standard for oil, FKM is for high-temp/chemicals. din 3760 pdf

For engineers, technicians, and procurement specialists, having a file containing dimension tables, tolerance charts, and cross-sections is essential. Tameson: Provides a comprehensive technical guide.

When looking up data sheets or a DIN 3760 PDF matrix, seals are categorized by three primary dimensions measured in millimeters (mm): : Inner Diameter (Shaft Diameter) : Outer Diameter (Housing Bore Diameter) : Seal Width (Thickness) The Standard Designation Form

The housing bore should be machined to an H8 tolerance. The standard applies to seals used on rotating

The standard ensures interchangeability between different manufacturers. If a seal is built to DIN 3760 specifications, a Type A seal from one brand will fit the exact same housing as a Type A seal from another brand. Standard Seal Types Under DIN 3760

Used for extreme speeds or dry-running conditions where traditional elastomers would fail. Installation and Maintenance Best Practices

Use a mechanical press tool or sleeve that contacts the outer edge of the seal casing uniformly. Applying force directly to the flexible lip or inner spring area will distort the component. are the most common variants (with/without dust lip)

Standard mineral oils, grease, water, and general hydraulic fluids. FKM / Viton® -30°C to +200°C Up to 35 m/s

Do you need help finding a cross-referencing these standard part numbers?

The effectiveness of a DIN 3760 seal depends heavily on the elastomer chosen for the application.

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
