Oil Seals

Oil Seals though static but are considered amongst the dynamic type of seals.An Oil Seal mainly consists of metal case, rubber and garter spring.Metal Case:The metal case plays a vital role in maintaining the retention strength between the seal and the housing bore, thus keeping the seal lip in its intended position.Rubber:The rubber in oil seal should be carefully selected, based on its application, media to seal and the temperature it has to stand.Garter Spring: A garter spring increases and maintains the pressure of the sealing lip on the shaft to provide adequate receive load on the sealing edge.They are simply stated as a component of machine that seals lubricants by preventing them from leaking as well as prevents the entry of dust and dirt into the machine. The sealing is generally provided between a rotating shaft and a stationary member. In vast cases the internal pressure against which a seal has to work is as low thus a single lip seal is adequate. The selection of the seal is based on seven basic points namely, shaft diameter, housing bore, width, shaft speed working temperature, medium in use and pressure.
