The standard, officially titled "Rotary shaft lip seals" , establishes the fundamental structural dimensions, testing guidelines, and performance metrics for radial oil seals used worldwide. Engineers, maintenance professionals, and procurement specialists frequently seek out a DIN 3760 PDF to verify precise engineering tolerances, compound boundaries, and installation instructions necessary to keep unpressurized rotating machinery running efficiently.

The DIN 3760 PDF is an essential engineering tool for anyone specifying, selecting, or installing radial shaft seals. It defines the dimensions, materials, design types, and performance limits for one of the most commonly used dynamic sealing elements in mechanical engineering. The standard has been stable since its 1996 revision and remains actively in force, with a corrigendum issued in 2019.

The standard classifies rotary shaft seals into distinct types based on their design, housing material, and the presence of an auxiliary dust lip. Type A (Standard Single Lip) For Type A (rubber OD) seals, a maximum

The DIN 3760 standard specifies the dimensions, designations, materials, and testing requirements for rotary shaft lip seals (commonly called oil seals or shaft seals). It applies to seals used in rotating shafts to retain fluids (like oil or grease) or exclude dirt, dust, and moisture.

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

A tension spring that ensures consistent, radial pressure is applied to the sealing lip against the shaft. Common Seal Forms (A vs. AS) Key Specifications from DIN 3760 The standard, officially
