Standard DIN 3760 seals are typically designed for low-pressure environments (up to 0.5 bar). Temperature Range: Varies by material, typically ranging from negative 40 raised to the composed with power C positive 200 raised to the composed with power C Why You Might Need the PDF Engineers and procurement teams often look for the DIN 3760 PDF to access: Tolerance Tables: Exacting measurements for housing bores ( ) and shaft finishes. Installation Guides:
Feature metal outer casings (B) or double metal casings (C) for more rugged housing fits. Tameson.com 2. Shaft and Housing Requirements
These seals are commonly known as oil seals, lip seals, or radial shaft seals. The standard ensures interchangeability between different manufacturers and guarantees a baseline level of performance and quality. Core Components of a DIN 3760 Seal
The standard classifies rotary shaft seals into several primary types based on their construction and the presence of a dust lip. The most common types utilize a rubber-covered metal outer sleeve to ensure optimal sealing inside the housing bore. din 3760 pdf
When looking for a , engineers, buyers, and maintenance professionals are typically seeking a definitive technical reference to ensure cross-brand interchangeability and system compatibility. This comprehensive guide provides an in-depth breakdown of the standard’s specifications, standard design forms, material selections, and vital installation guidelines required for optimal application performance. 1. What is the DIN 3760 Standard?
An outer elastomer-covered metal insert. This is the most common type, providing excellent sealing at the housing even with thermal expansion.
A tension spring that ensures consistent, radial pressure is applied to the sealing lip against the shaft. Common Seal Forms (A vs. AS) Standard DIN 3760 seals are typically designed for
: Hardness of at least 45 HRC is required (increasing to 60 HRC at higher speeds) with a surface roughness of Racap R sub a 0.2 to 0.8 µm. 2. Standard Design Forms
Platforms like GlobalSpec offer summaries and paid access to the official documentation.
Using seals that comply with DIN 3760/ISO 6194 guarantees interchangeability. If a machine requires maintenance, you can source a replacement seal from various reputable suppliers without needing a custom part. This reduces downtime and simplifies supply chains. Tameson
If you are looking to download a official copy of the , it is commercially available through the Beuth Verlag registry or national standardization bodies like ISO/DIN portals.
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.
