This guide provides a detailed overview of the DIN 3760 standard, its types, material selection, installation guidelines, and how to find technical documentation (PDFs). 1. What is DIN 3760?
The DIN 3760 standard commonly categorizes seals into two main design forms:
: By adhering to the guidelines and specifications in the DIN 3760 PDF, manufacturers can ensure that their radial shaft seals contribute to the overall safety and reliability of the machinery.
DIN 3760 is a German standard that specifies the requirements for radial shaft seals, also known as rotary shaft seals. These seals are used to prevent the leakage of fluids (such as oils, greases, and other lubricants) from rotating machinery, ensuring that the lubricant stays within the system and contaminants stay out. The standard covers various aspects, including design, dimensions, materials, and testing methods for radial shaft seals.
DIN 3760 covers ready-to-install rotary seal components for unpressurized equipment or equipment with low differential pressure. By standardizing the designs, nominal dimensions, and tolerances, DIN 3760 ensures that components from different manufacturers are interchangeable. Key Aspects Defined by DIN 3760: din 3760 pdf
As she began to read through the document, Emma learned that DIN 3760 specified the requirements for rotary shaft seals, including their design, dimensions, and testing. She was relieved to find that the standard covered the exact type of seal she needed.

is acceptable. For Type B (metal OD) seals, a finer finish of is necessary. Elastomer Material Selection
The DIN 3760 PDF contains the following essential technical information: This guide provides a detailed overview of the
The metal insert is completely encased in elastomer (rubber).
Similar to Type A but includes an additional protective lip (dust lip) to prevent contamination from entering.
There is often confusion regarding the latest version. As of today, the current technical specification is . This standard is still marked as active or "aktuell" by the DIN institute. The 2019 corrigendum (Corr. 1) is an editorial correction to the 1996 version, not a new edition.
Must be rounded and free of burrs to prevent damaging the seal lip during assembly. Housing Bore Requirements Tolerance: Typically machined to an H8 tolerance zone. Surface Roughness: for rubber OD; for metal OD. Why Engineers Download the DIN 3760 PDF The DIN 3760 standard commonly categorizes seals into
When searching for a din 3760 pdf , you are technically looking for the 1996-09 version plus the 2019 corrigendum. The standard is published by the and comprises 12 to 14 pages depending on the source.

Features an elastomeric outer sleeve. It is ideal for housings with high thermal expansion (e.g., light metal) or significant surface roughness. Type B (Metal Cased):
Maximum operational pressure tolerances (typically up to 0.05 MPa for standard types).
