Our company produces KP-09 ultra-high-molecular-weight sheave liners using imported materials, which boast exceptional wear resistance (with a mortar abrasion rate just 1/10 that of PVC, 1/7 that of carbon steel, and 1/27 that of brass), excellent impact resistance (achieving an impact strength of up to 180 kJ/m² or higher), outstanding self-lubricating properties (with a friction coefficient of only about 0.10), and remarkably high tensile strength (exceeding 35 MPa). Additionally, these liners exhibit superb corrosion and water resistance, maintaining excellent stability across a wide range of organic and inorganic media. They also deliver exceptional low-temperature performance and are completely hygienic and non-toxic.
We can produce products in various shapes and specifications according to customer requirements.KP-09 Ultra-High Molecular Wheel Sheave Lining Pads KP-09 Ultra-High Molecular Wheel Sheave Lining Pads are high-performance engineering plastic components specifically designed for mine hoist systems, head sheaves, deflector wheels, and heavy-duty cable transmission machinery. Engineered from specialized ultra-high molecular weight synthetic polymers, KP-09 pads serve as a protective barrier inside the sheave groove, preventing direct metal-to-metal contact between the wire rope and the steel sheave.
Key Features & Operational Advantages:Superior Rope Protection & Low Friction: Featuring an extremely low coefficient of friction (~0.10) and exceptional self-lubricating properties, KP-09 lining pads allow wire ropes to pass smoothly with minimal resistance. This significantly reduces rotational torque and torsional stress on the wire rope, preventing internal wire damage and substantially extending the service life of expensive hoisting cables.Exceptional Wear & Impact Resistance: KP-09 ultra-polymer exhibits outstanding resistance to abrasive wear—outperforming traditional materials like PVC, nylon, carbon steel, and brass. Its high impact strength (over 180 kJ/m²) absorbs shock loads and operational vibrations without cracking or fracturing. High Load Capacity & Structural Integrity: With high tensile strength (35+ MPa) and dynamic compression resistance, KP-09 maintains its structural integrity and groove dimensional stability even under heavy loads and continuous high-cycle operations. Chemical & Environmental Durability: Non-corrosive, waterproof, and chemically stable, KP-09 withstands moisture, harsh mine environments, and a wide operating temperature range (down to sub-zero conditions) without degrading or losing its mechanical strength.Versatile Customization: Manufactured in various geometric segments, radiuses, and profiles, these lining pads can be custom-machined or molded to fit different sheave wheel diameters, rope pitch gauges, and mounting configurations.Primary Applications:Ideal for replacing traditional wood, rubber, or basic nylon liners, KP-09 Sheave Lining Pads are widely implemented across single-rope and multi-rope mine hoisting systems, aerial ropeways, tower cranes, port loading machinery, and heavy industrial winch assemblies.
