Abstract
A grease seal cup for a splined joint between a drive shaft and a driven shaft comprises a cylindrical portion adapted to form a seal with the outer surface of the drive shaft and a seal with a sealing member, such as a spanner nut, of the driven shaft. The grease seal cup, comprising a flexible polymer material, tightly squeezed during installation to form the seals. The pre-fabricated light weight grease seal cup can be used in existing splined joints without adversely affecting the weight balance.
