Component Specifications

Definition
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.
Working Principle
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.
Materials
Typically made from synthetic rubber (NBR, FKM, silicone), polyurethane (PU), or thermoplastic elastomers (TPE). Advanced versions may include felt layers, stainless steel scrapers, or fabric reinforcements. Material selection depends on temperature range (-40°C to 200°C), chemical resistance, and environmental conditions.
Technical Parameters
  • Hardness 70-90 Shore A
  • Compression Set <20%
  • Protection Level IP54 to IP67 equivalent
  • Installation Type Snap-fit, adhesive-backed, or integrated
  • Operating Temperature -30°C to 120°C
Standards
ISO 10243, DIN 648

Engineering Analysis

Risks & Mitigation
  • Contamination ingress leading to premature bearing failure
  • Material degradation from incompatible chemicals
  • Improper installation causing seal leakage
  • Reduced effectiveness in high-speed applications
FMEA Triads
Trigger: Abrasive particles embedding in seal material
Failure: Accelerated wear on guide raceways and balls
Mitigation: Use multi-layer seals with external wipers; implement regular cleaning protocols
Trigger: Thermal expansion mismatch between seal and metal components
Failure: Loss of sealing contact at temperature extremes
Mitigation: Select materials with compatible thermal coefficients; design with expansion gaps

Frequently Asked Questions

How often should sealing strips be replaced on linear guides?

Replacement intervals depend on operating environment and hours of use. In clean conditions, inspect annually; in contaminated environments, check every 3-6 months. Replace when visible wear, hardening, or loss of sealing contact occurs.

Can sealing strips be used with different lubricant types?

Yes, but material compatibility is crucial. NBR seals work with mineral oils and greases, while FKM seals handle synthetic lubricants and chemicals. Always verify chemical resistance charts.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
