ABSTRACT:
The annular seal is located in the annular space between a first member and a second member of a bearing. The seal has an annular lip portion normally in contact with one of the members around the entire circumference of the seal to keep lubricant in the annular space behind the annular seal. The seal has protrusions behind that portion of the lip which contacts the member and at circumferentially spaced locations on the annular seal. The protrusions are adapted to keep the back portion of the annular seal adjacent each side of the protrusions spaced from the member the lip contacts.
