Sealing Strips (Optional): Width 5-50 mm, Thickness 1-10 mm

Q: When should sealing strips be used on positioning guides or rails?

Sealing strips are recommended in environments with high dust, moisture, or chemical exposure to prevent contamination, reduce wear, and minimize maintenance needs.

Q: Are sealing strips interchangeable between different guide or rail brands?

No, sealing strips are typically designed for specific guide or rail profiles and dimensions; compatibility depends on manufacturer specifications and mounting systems.

Component Specifications

Definition

Sealing strips are flexible, optional components installed along positioning guides or rails in industrial machinery to create a barrier against dust, debris, liquids, and other contaminants. They protect critical linear motion surfaces, reduce maintenance frequency, and enhance operational reliability in harsh environments.

Working Principle

Sealing strips function by forming a physical barrier between the moving parts of positioning guides/rails and the external environment. Their flexible design allows them to maintain contact with surfaces while accommodating minor misalignments and vibrations, preventing ingress of contaminants that could cause wear, corrosion, or jamming.

Materials

Typically made from polyurethane (PU), nitrile rubber (NBR), silicone, or thermoplastic elastomers (TPE) with Shore A hardness ranging from 60-90, offering flexibility, chemical resistance, and durability.
