SCHNEEBERGER MONORAIL offers a variety of special version options to meet the needs of specific application environments. This chapter introduces coating technology and stainless steel models, suitable for applications requiring higher corrosion resistance or special environmental conditions.
4.15.1 Coatings
Guide rails and carriages can be optionally equipped with special coatings to improve corrosion resistance and environmental adaptability.
Coating Types
Anti-Corrosion Coating
Suitable for humid or corrosive environments, providing additional surface protection.
Wear-Resistant Coating
Extends service life, suitable for high-load or high-frequency motion applications.
Low-Friction Coating
Reduces friction coefficient, improving motion smoothness and energy efficiency.
Application Recommendations
- Food processing equipment: Select coatings that meet hygiene standards
- Marine environment: Use highly corrosion-resistant coatings
- Cleanroom applications: Select low dust-generating coatings
- High-temperature environment: Use special high-temperature resistant coatings
Note
Coating selection should be based on comprehensive consideration of factors such as specific application environment, temperature range, and chemical substance exposure. Consultation with the SCHNEEBERGER technical team is recommended to select the most suitable coating solution.
