Metric rotary shaft seal in nitrile rubber comes complete with a shaft garter spring.
Also known as an oil seal, shaftseal, or lip seal. Its function is to exclude dust, dirt, water or any other contaminant on one side whilst retaining lubricant on the other. Generally it has been developed as a means of protecting the bearings of rotating shafts.
The basic operation of a shaft seal has the flexible lip held against the rotating part (usually the shaft) whilst the casing (or O.D.) is pressed into the housing or bore holding the seal in place. The sealing lip needs some form of lubrication to avoid overheating and are usually energized by means of a garter spring.
