If you need to find a specific or material compatibility chart , let me know! I can help you: Find the correct dimensions for your shaft size. Compare NBR vs. FPM/FKM for your specific fluid. Identify equivalent ISO standards (like ISO 6194).
High safety for static sealing; housings with high thermal expansion. Rubber-covered outer diameter with an additional
DIN 3760 specifies the dimensions and requirements for rotary shaft lip seals. It ensures that seals from different manufacturers are interchangeable, provided they meet the standardized geometric and material criteria. Common Seal Types Under DIN 3760

The standard has undergone several revisions to keep pace with technological advancements. The current active edition is , released in September 1996. It replaced older editions from April 1972 and February 1962.
Bare metal outer casing reinforced with an inner metal structural shell.
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. You aren't just looking for a casual read
DIN 3760 is a German Institute for Standardization (DIN) standard that specifies the dimensions, tolerances, and design requirements for .
Offers technical catalogues including DIN 3760 and ISO 6194 specifications. Scribd: Often hosts documents titled "Retentor Din 3760".
A: Those are based on DIN 3760. "B" = Metal case, "A" = Dust lip, "BSL" = Heavy-duty spring. The standard defines these codes.
What are the and shaft speeds (RPM) ?
Provides a tighter, more secure press-fit into the housing bore. Requires closer tolerances on the housing bore to prevent static leakage around the outside of the seal. Type BS: Metal Outer Diameter with Dust Lip
If you only require dimensions, tolerance charts, or material compatibility data rather than the legal testing framework, downloading a is an excellent alternative. Leading global seal manufacturers (such as Freudenberg Sealing Technologies/Simrit, SKF, Trelleborg, or Dichtomatik) publish exhaustive, free-to-download PDFs. These catalogs replicate the exact DIN 3760 geometric dimensions and offer comprehensive engineering application data. If you need help implementing these standards, tell me: What fluid or chemical will the seal be containing?
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.
The standard provides precise guidelines to ensure interchangeability and performance across different manufacturers. Rotary shaft lip seals DIN 3760 | norelem Compare NBR vs
