Abstract
Non-contacting seal for shafts rotating at high speeds with improved centering means for low unbalance of seal rotating parts. Centering means comprise a shallow circumferential groove with slanted sides and an elastic centering strip of ladder-like form between two cylindrical surfaces to be held concentric. Since slanted sides of the groove overlap sides of the centering strip it cannot be displaced out of its groove during assembly, or during operation. Displaced centering strip could cause unbalance, vibrations, damage to the seal or to the surrounding equipment.
