Sealing strips are essential protective components installed on linear guide tracks to create a barrier against external contaminants such as dust, chips, and liquids. They maintain the internal lubrication system, reduce wear on rolling elements and raceways, extend service life, and ensure consistent precision in linear motion applications across industrial machinery.

Sealing strips function by forming a physical seal between the moving carriage and stationary track of a linear guide. They use flexible materials (often with integrated lips or brushes) that maintain contact with surfaces, scraping away contaminants and retaining lubricants. Some designs incorporate labyrinth seals or multi-layer structures to enhance protection in harsh environments.
