Often caused by sharp edges on the shaft keyway scoring the delicate sealing lip during assembly. Always use an installation sleeve over keyways.
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.
Requirements for shaft condition, roughness, and housing tolerance.

DIN 3760 is a widely accepted standard in the industry for radial shaft seals used in rotating equipment, such as pumps, gearboxes, and motors. The standard specifies the design, materials, and testing requirements for radial shaft seals to ensure their performance, reliability, and durability.
The standard also specifies the metallic casing material (typically non-corrosive steel like DC01 or DX51D) and the garter spring material (usually stainless steel or carbon steel).
For most practical purposes, the dimensions remain the same. If you are searching for a DIN 3760 PDF, you will find that the dimensions listed in ISO 6194 documentation correspond exactly to the legacy DIN specifications.
If you're interested in accessing the DIN 3760 standard, you can purchase and download a PDF copy from various sources, including: Often caused by sharp edges on the shaft

Never hammer directly on the seal, as this will deform the metal casing and permanently damage the sealing lip.

is the German industrial standard (Deutsches Institut für Normung) that defines the dimensions, design, material, and performance requirements for radial shaft seals (often called Rotary Shaft Lip Seals or oil seals) used to seal rotating shafts against stationary housings. These seals, which typically consist of a rubber-like sealing lip and a metal insert, are crucial for retaining lubricants (oil or grease) inside a machine while preventing the ingress of contamination.
