The DIN 3760 standard specifies dimensions and technical requirements for rotary shaft lip seals used to retain fluids or grease in unpressurized equipment, or equipment operating under low differential pressures (typically up to 0.05 MPa or 0.5 bar). Core Seal Anatomy
Used primarily to retain lubricants. The elastomer outer diameter (OD) provides excellent sealing capabilities inside the housing bore, even if the housing expands thermally or has minor surface roughness. Type AS (Single Lip with Dust Lip)
The standard outlines critical parameters for effective sealing and service life: 1. Standard Design Types
There are three primary construction forms defined by the standard:
DIN 3760 permits two primary sealing lip materials: din 3760 pdf
: The standard outlines the performance requirements and testing methods for radial shaft seals. By referring to the DIN 3760 PDF, manufacturers can ensure that their products meet the necessary quality and performance standards.
Extreme thermal applications with low physical stress. Poor dry-running properties. Polyacrylate Rubber -25∘Cnegative 25 raised to the composed with power C +130∘Cpositive 130 raised to the composed with power C
Even the highest-quality seal manufactured to DIN 3760 specifications will fail if installed incorrectly.
Performance is heavily dependent on the chosen elastomer and shaft operating conditions. The DIN 3760 standard specifies dimensions and technical
The DIN 3760 standard laid the groundwork for the modern radial shaft seals we use today. While you should reference for the most current official documentation, the dimensional legacy of DIN 3760 remains the industry standard.
It is important to note that while "DIN 3760" is still widely used as a term in the industry, the standard has been officially replaced by .
If you are looking for the DIN 3760 PDF, you are likely checking for one of the following specifications:
Provides static sealing against the housing. Type AS (Single Lip with Dust Lip) The
The performance of a DIN 3760 seal is heavily dependent on the counter-surface: Shaft Hardness:
Curiosity held her. She scanned the sheet into her tablet and searched the network. A faded PDF appeared in the results, a scanned standard decades old, brittle pages stitched into a single file: DIN 3760.pdf. The document described rubber lip seals in clinical, technical language — tolerances, surface finishes, installation clearances. But tucked between tables and tolerances was a handwritten note in the margin: “Tested, 1987 — runs quiet. — HK.”
In modern mechanical engineering, the containment of lubricants and the exclusion of environmental contaminants are critical to machine longevity. The foundational standard governing these components is , established by the German Institute for Standardization ( Deutsches Institut für Normung ). It defines the dimensional frameworks, material requirements, testing procedures, and installation parameters for radial rotary shaft lip seals.
, which are used to seal rotating machine components. These seals typically consist of an elastomer (rubber) part, a metal reinforcement plate, and a garter spring. Tameson.com
