The X1 Sealing Concept provides both a highly effective interior and exterior seal for ball screws. The inner part of the seal prevents the leakage of lubricants, while the outer part prevents the penetration of contaminants into the body of the nut. The labyrinth seals serves as a reference point. Seals provide are a major improvement in terms of performance and function. X1 Seal development demonstrates improved seal performance and reduced friction.
