Ball screw seals: Types, options, and applications Linear
The simplest is the brush seal. Although brushes don’t provide a tight, continuous seal with the screw shaft, they are very effective at wiping, or brushing away, larger contaminants and preventing them from entering the ball nut. Brushes are often used in conjunction with other types of full-contact seals, such as lip seals or segmentedA brush seal is comprised of arcuate seal segments having ends cut in a radial direction with bristles "canted" at an approximate 45° angle relative to radii of the segments, leaving triangular regions adjacent one end of each segment devoid of bristles at the segment interfaces. The brush seals are retrofit into conventional labyrinth seals with the backing US5749584A Combined brush seal and labyrinth seal

Brushes as High Performance Gas Turbine Seals Semantic
Brush seals are the first simple and practical alternative, to the finned labyrinth, for gas turbine air system seals. Their use has been made possible by a combination of innovative design features, combined with advanced materials and manufacturing techniques.Due to the very high rubbing speeds and temperatures, existing in gas turbine air system seal Heavy rubber seal stands up to the elements.

IMPROVED STEAM TURBINE LEAKAGE CONTROL WITH
Brush seals have been used in aircraft engines since the early 1980s (Flower, 1990; Mahler and Boyes, 1995) and were introduced first into gas and then steam turbines in the mid 1990s (Wolfe, et al., 1997). The continuing development work on steam turbine brush seals leverages effort on aircraft engine, industrial gas turbine, and Flintlocks: How to Shoot Them CHUCKHAWKS.COM. For the past 60 years or more we have been stuck with the idea that the cloth patch we use with a round ball performs two functions: it grabs the ball and imparts the spin of the rifling to the ball as it travels down the barrel, and it seals the bore so that gases behind the ball cannot cut past the edge of the brush seals for ball mill

Introduction of new sealing technologies for steam turbines
A well-designed tip brush seal will not only survive the harsh environment at the bucket tip where high disturbances from both flow and interrupted rotor surface could be fatal, but also maintain a sustainable performance as a contact seal. Fig. 14.5 shows tip brush seals after 6 years of operation with known presence of solid particles. StepsLabyrinth Seals (a.k.a. Leidenfrost Seals or Mini Maze) have maze-like peaks that form between the inner and outer rings. This unique design keeps contaminants out and ensures the inner and outer rings of the seal stay inseparable. The steel inner ring is surrounded by molded aluminum.

Brush Seals for Improved Steam Turbine Performance
GE Energy has retrofitted brush seals into more than 19 operating steam turbines. Brush seals offer superior leakage control compared to labyrinth seals, owing to their compliant nature and ability to maintain very tight clearances to the rotating shaft. Seal designs have been established for steam turbines ranging in size from 12 MWA non-metallic brush seal has been developed as an oil seal for use in turbomachinary. Traditionally labyrinth-type seals with larger clearances have been used in such applications. Labyrinth seals have higher leakage rates and can undergo excessive wear in case of rotor instability. Brush seals reduce leakage by up to an order of magnitude and provide Non-Metallic Brush Seals for Gas Turbine Bearings
