4. Technical Requirements for Installation (DIN 3760 Guidelines)

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.

Whether you are a maintenance engineer, a design technician, a procurement manager, or a student, you have likely searched for the term . This article serves as your definitive guide. We will cover what the standard dictates, the types of seals involved, technical specifications, and—crucially—how to legally and safely access the official DIN 3760 PDF document.

According to DIN 3760, minimum hardness should be 45 HRC , increasing to 55 HRC at higher peripheral speeds.

DIN 3760 is a technical standard developed by the German Institute for Standardization (Deutsches Institut für Normung). It specifies the dimensions and requirements for rotary shaft lip seals, commonly known as oil seals or lip seals.

is the German industrial standard that defines the dimensions and technical requirements for Rotary Shaft Lip Seals

Minimum 45 HRC (Rockwell C) for clean lubricants; minimum 55 HRC if external abrasive contaminants are present. This prevents the sealing lip from wearing a groove into the shaft. : Available at the ANSI Webstore or Beuth Verlag

Under DIN 3760, seals are typically categorized by their construction: Type A (Single Lip): A basic seal designed to retain lubricants. Type AS (Single Lip with Dust Lip):

: This is the most versatile and widely used type. The rubber-coated outer diameter ensures a leak-proof static seal against the housing, even if the housing bore has minor surface imperfections or thermal expansion issues.
