Excavator Couplings by YNF – Reliable and Durable Solutions

At YNF, we specialize in manufacturing excavator couplings designed for high durability and efficiency. With over 40 years of experience, we provide high-quality aftermarket excavator couplings that serve as perfect replacements for various brands and models.

What is an Excavator Coupling?

An excavator coupling (also known as a coupler or connect rubber) is a crucial component that connects the engine (power provider) to the hydraulic pump (transmission system) in an excavator. It ensures smooth power transmission while absorbing vibrations, reducing mechanical stress, and enhancing the lifespan of both the engine and the pump.

In crawler hydraulic excavators, couplings play an essential role in maintaining the efficiency and longevity of the machinery by minimizing wear and tear caused by torque fluctuations and shock loads.
