Supplier's note

1. Technical Breakthroughs:

   • NBR Material: Offers 30% better oil resistance than standard rubber, extending lifespan in hydraulic systems.
   • Gear Structure: Reduces rotational slippage by 15% compared to sleeve-type couplings, ensuring precise motion control.
   • Flexible Design: Accommodates 2x more misalignment than rigid couplings, minimizing downtime in uneven terrain.

2. Version Selection Guide:

   • Base Model: Ideal for standard excavator maintenance or light-duty applications where cost efficiency is prioritized.
   • Advanced Model: Suited for mid-sized construction sites requiring higher torque and heat resistance (e.g., asphalt plants or demolition work).
   • Pro Model: Designed for extreme environments (e.g., Arctic mining or high-temperature foundries) with heavy-duty machinery.

With the Pro Model’s 4 mm misalignment tolerance, operators can maintain excavator functionality even on uneven terrain. Pair its NBR material with high-torque specs to ensure seamless operation in corrosive or abrasive conditions.
