Oil seals play a crucial role in all rotating and moving part assembly as they act as a physical barrier to retain lubricants, whilst excluding dirt, moisture and other contamination. They are manufactured in a wide range of sizes and specifications to meet several demanding sealing applications across industries. This post, which has two parts, discusses some of the must know things about oil seals. Read on to understand the seals better!
Designed to offer optimum sealing performance, oil seals guarantee extreme durability even under high-peripheral speed. They are light-weight, compact, and exhibit high self-lubricating performance. As oil seals are manufactured using high-grade materials, they last long without showing the signs of any kind of hardening, softening or ageing.
As mentioned earlier, oil seals are available in varied designs to best match the applications. A few of the commonly available types include:
ㆍType A single lip rubber coated w/spring
ㆍType ADL double lip rubber coated w/spring
ㆍType AO single lip rubber coated - no spring
ㆍType AODL double lip
ㆍType B single metal lip-metal case w/spring
ㆍType BDL double lip
ㆍType BO single lip - metal case
ㆍType BODL double lip metal case
ㆍType C single lip full metal case w/spring
Choosing the right seal is important as it determines the sealing performance by effectively preventing the leakage of lubricating oils and the ingress of contaminants.
Oil seals are made from several materials. However, the material must be chosen considering several parameters including operating temperature, environment, pressure, and maximum shaft surface speed, among others. The most commonly used materials for oil seal construction are as follow:
ㆍFluoroelastomer ( Viton )
ㆍGeneral Purpose Polyurethane
