What is Difference between Double and Single Lip Seal
Updated 03/27/2017 | Published 03/24/2017
Question:
Is a single or double lip seal a type of mechanical or industrial seal?
asked by: Michelle
Expert Reply:
The difference between the single lip and double lip seals is that the double lip grease seal will have two rubber lips that are in contact with the spindle. The double lip grease seals are usually used in marine applications to give a better seal and protect the bearings from the water, which can cause damage to them.
The best way to determine what grease seals are needed for your spindle is to get the part numbers from the inner and outer bearings from that spindle. If you have the bearing part numbers, then I can help you get the correct single lip or double lip grease seal that you will need.
See the picture that will show the cross section of both the single lip and double lip grease seals.
