Our company, based in Shijiazhuang, Hebei Province, China, manufactures nylon Lebus sleeves designed to fit over smooth steel drums. These sleeves provide the precision of Lebus groove technology while offering the unique advantages of non-magnetic, insulated, and signal-safe nylon materials.
They are widely used in winch systems, hoisting machinery, marine equipment, and engineering lifting devices, offering a lightweight and durable solution for accurate rope management.
The nylon Lebus sleeve is a removable, precision-machined component installed over a smooth drum. Each sleeve features double-helical Lebus grooves that guide the wire rope layer by layer, ensuring uniform tension and perfect winding.
Unlike traditional metal sleeves, our nylon Lebus sleeves are made from engineering-grade polymer materials, which offer:
Non-magnetic properties
Electrical insulation
Resistance to corrosion and moisture
Compatibility with signal transmission systems
This makes them especially suitable for electromechanical equipment, marine communication winches, and sensitive lifting systems.
Customizable Design
Available in various colors, sizes, and materials, allowing full customization for different rope diameters, drum types, and application environments.
Non-Magnetic and Signal-Safe
The nylon material is completely non-magnetic, ensuring it does not interfere with electronic sensors, control systems, or communication signals during operation.
Electrical Insulation
Offers excellent insulation performance, enhancing safety in electric winches and high-voltage working conditions.
Lightweight and Easy to Replace
Nylon sleeves are much lighter than metal sleeves, reducing total drum weight and allowing for fast installation or replacement.
High Wear and Impact Resistance
Engineered nylon provides excellent resistance to friction, wear, and surface damage from wire ropes.
Corrosion and Moisture Resistance
Ideal for use in marine and outdoor environments, preventing rust or degradation over time.
Our nylon Lebus sleeves are suitable for a wide range of industries and equipment, including:
Marine and offshore winches
Construction and hoisting machinery
Electrical and communication lifting systems
Geological exploration winches
Aerospace and defense lifting systems
The non-magnetic and insulated properties make them particularly valuable for equipment that integrates electronic sensors or communication components.
