01/09/2026

DAOLER diamond friction shims are engineered to leverage the exceptional properties of synthetic or natural diamond—including extreme hardness, superior thermal conductivity, outstanding wear resistance, and high chemical stability—to meet demanding performance requirements in a wide range of industries. Below are key application areas where these advanced components deliver critical benefits:

Automotive & New Energy Vehicles (NEVs)

● Torque Transmission Enhancement: Used in powertrain assemblies, especially for high-torque electric motors, to maximize torque transfer and improve power density.
● Lightweight & Compact Design: Helps reduce component size and weight without compromising durability, supporting lightweight vehicle strategies.
● Heat Management: Effectively dissipates heat generated at friction interfaces, protecting sensitive drivetrain and battery systems.
● NVH Reduction: Dampens vibration and reduces noise in structural and rotating assemblies, enhancing passenger comfort.

Robotics & Automation

● Precision Motion Systems: Applied in robotic joints, end-effectors, linkages, and grippers, where low inertia, high stiffness, and repeatability are critical.
● Vibration Control: Minimizes high-frequency oscillations in dynamic systems, improving positioning accuracy and operational stability.

● Compact & Lightweight Integration: Enables smaller, lighter actuator designs while maintaining load capacity and wear life.

Aerospace & Satellite Systems

● Critical Joint Protection: Secures bolted connections in airframes, engine mounts, and satellite platforms, preventing loosening under extreme vibration and thermal cycles.
● Weight-Sensitive Applications: Provides high strength-to-weight performance in launch vehicles, spacecraft mechanisms, and antenna positioning systems.
● Harsh Environment Durability: Resists corrosion, oxidation, and radiation, ensuring long-term reliability in orbital and atmospheric conditions.

Wind Energy

● High-Torque Wind Turbine Drivetrains: Maximizes torque transmission efficiency in gearboxes, couplings, and generator connections.
● Size & Weight Optimization: Enables the use of smaller fasteners and lighter components, facilitating transport, installation, and maintenance.

● Offshore & Onshore Reliability: Withstands variable loads, humidity, and salt exposure in demanding wind farm environments.

Industrial Machinery & Precision Equipment

● High-Speed Spindles & Machine Tools: Enhances rigidity and thermal stability in precision machining applications.
● Heavy-Duty Connections: Used in press fits, flange assemblies, and structural joints subject to cyclic loading.

● Chemical & Process Industries: Suitable for aggressive environments due to diamond’s inertness and resistance to chemical attack.

Emerging & Niche Applications

● Medical Devices: Applied in high-precision surgical robots and imaging equipment where reliability and cleanliness are paramount.
● Semiconductor Manufacturing: Used in wafer handling and positioning systems requiring ultra-low particle generation and thermal stability.

● Defense & Marine Systems: Protects critical connections in vehicles, vessels, and equipment exposed to shock, vibration, and harsh climates.

Key Advantages Across Applications
