: Similar to Form A but includes an additional dust lip (also called a protective lip) to provide extra protection against external dirt and grime.
Specifies dimensions, tolerances, material requirements, and performance tests for (type A, AS, B, BS, C, CS) used in automotive and industrial applications. din 3760 pdf
When reviewing a DIN 3760 PDF, you will typically find the following operating parameters: Standard Range (NBR) High-Performance (FKM/Viton) -30°C to +100°C -20°C to +200°C Peripheral Speed Up to 14 m/s Up to 37 m/s Pressure Max 0.05 MPa (0.5 bar) Up to 0.5 bar (standard) : Similar to Form A but includes an
One of the most overlooked sections in the PDF is the requirement for shaft surface finish. The standard typically calls for a specific roughness value (often Ra 0.2 to 0.8 µm). If the shaft is too smooth, the seal cannot "pump" oil back in; if it is too rough, the lip wears out rapidly. The PDF serves as a guide for the machining process. The standard typically calls for a specific roughness
Before downloading a PDF, it helps to understand the basic structure. A typical DIN 3760 seal is specified as:
In the world of mechanical engineering and industrial design, rotary shaft seals are the unsung heroes of machinery. They ensure that lubricants stay where they belong and that contaminants stay out. Among the various standards governing these critical components, stands as one of the most historically significant and widely referenced specifications in the industry.
If you have the DIN 3760 PDF, you are 99% compliant with ISO 6194. Always check the "Normative references" section in your PDF to see which ISO standards are called out.
