When reading a DIN 3760 datasheet or ordering a part, the nomenclature follows a strict sequence: . Example: DIN 3760 AS 45 x 62 x 8 NBR AS: Rubber outer diameter with a dust lip. 45: Designed for a 45 mm shaft. 62: Fits a 62 mm housing bore. 8: The seal width is 8 mm. NBR: Manufactured using Nitrile butadiene rubber. Installation and Operating Requirements
For professional applications, it is strongly recommended to obtain the official, non‑modified PDF from authorized distributors. There is no legal, free download of the standard, and many PDFs found on file‑sharing platforms are incomplete, of poor quality, or contain errors. din 3760 pdf
: If the seal needs to withstand high internal pressures or must resist being pushed out of the housing, Type B with its metal outer case is preferred. However, it requires a much more precise housing bore finish. When reading a DIN 3760 datasheet or ordering
. There is an entirely different standard, DIN EN 3760 , which applies to aerospace screws . If you mistakenly search for “DIN EN 3760,” you will get specifications for countersunk screws made of corrosion‑resistant steel, not the shaft seal standard discussed here. Always search for “DIN 3760:1996-09” to avoid this confusion. 62: Fits a 62 mm housing bore
The standard ensures that oil seals from different manufacturers are and meet specific performance benchmarks. It covers:
