<p>A hydrodynamically lubricated squeeze packing type rotary shaft seal (105) suitable for lubricant retention and environmental exclusion which incorporates one or more resilient protuberances (200) which cooperate with the gland walls to hold the seal straight in its installation groove (104) in unpressurized and low pressure lubricant retention applications thereby preventing skew-induced wear caused by inpingement of abrasive contaminants present in the environment, and which also serve as radial bearings to prevent tipping of the seal within its installation gland.</p> |
