Product Description

This product is a metal-rubber integrated flexible coupling component, with high-elasticity NBR (nitrile butadiene rubber) as the main material. It uses a thermal bonding process to firmly bond the rubber elastomer with aluminum alloy structural parts. It features excellent flexible buffering, vibration suppression and torque transmission functions, making it the preferred choice for flexible connection solutions in various fans, motors and precision equipment.

PRODUCT FUNCTION

Highly elastic vibration absorption: NBR features a high elastic modulus, capable of absorbing impact loads and dynamic torque, reducing the risk of system resonance;  

Transmission noise reduction: Effectively converts vibration energy into thermal energy, reduces high-frequency noise, and enhances the quietness of equipment operation;  

Dynamic balance assurance: Particularly suitable for fan blades and rotating shaft systems, maintaining stable high-speed operation and avoiding asymmetric wear;  

Excellent durability and oil resistance: The rubber has outstanding oil resistance (to lubricating oil, fuel oil) and fatigue resistance, extending service life;  

Adaptability to complex working conditions: Operating temperature range from -40℃ to +120℃, suitable for scenarios with high temperature, high load, and high-frequency vibration.
