Abstract
A seal assembly having a seal bumper wall with a series of pyramid shaped formations lying on the bumper wall. The formations cause their apex portion to wear down rapidly in use, while the remainder of the pyramids remain and act as slingers and/or produce a convection effect to reduce temperature along the sealed area. In another embodiment, there are two each pyramid shaped formations located on each of several thrust bumpers, which are held in position by a retainer.
