Spring Loaded Oil Seals assembled on rotary shaft made from elastomers with reinforced metal, mainly used for oil or grease retention.
This type of oil seal uses a garter spring to maintain a constant radial load on the shaft to become more efficient. The Rubber covered at outer diameter press fits to create a positive seal with the housing bore.
The additional dust lip protects the mail sealing lip against dust and other foreign particles and therefore this type is suitable for use in polluted environments
Advantages:
- Good static sealing
- Compensation of different thermal expansion
- Reduced risk of fretting corrosion
- Effective protection against air side contaminants
- Modern lip design provides low radial forces
