: Standard material; resistant to petroleum-based fluids. Operational from -30°C to +100°C FKM (Fluorocarbon / Viton)

The standard, established by the German Institute for Standardization (Deutsches Institut für Normung), is the definitive technical guide for the design, dimensions, and requirements of rotary shaft lip seals . Often referred to as "Simmerrings" or oil seals, these components are critical for retaining lubricants and preventing the ingress of dirt in unpressurized or low-pressure rotating equipment.

From the perspective of designers, maintenance engineers, and procurement specialists, having access to the official is crucial for several reasons: din 3760 pdf

A standard DIN 3760 seal generally consists of three main components:

Few standards are as deeply woven into the fabric of modern mechanical engineering as . This German standard, formally titled "Rotary shaft lip type seals" ( Radial-Wellendichtringe ), serves as the international benchmark for the design, dimensioning, and application of radial shaft sealing rings—commonly known as oil seals. : Standard material; resistant to petroleum-based fluids

The shaft surface must have a minimum hardness of 45 HRC. For high peripheral speeds or abrasive environments, a hardness of 55 HRC to 60 HRC is recommended.

A successful seal depends on precise fits. According to the standard: For high peripheral speeds or abrasive environments, a

For professional applications, it is strongly recommended to obtain the official, non‑modified PDF from authorized distributors. There is no legal, free download of the standard, and many PDFs found on file‑sharing platforms are incomplete, of poor quality, or contain errors.
