Introduction to Polymer Cage Technology for Automotive Systems
In the modern automotive sector, the push for NVH (Noise, Vibration, and Harshness) reduction and lighter vehicle components is relentless. Our Polymer Cage Automotive Bearings offer a crucial advantage by utilizing high-strength, glass-fiber reinforced Polyamide (PA66) cages. This design drastically reduces the bearing’s rotating mass, minimizes internal friction, and dampens operational noise compared to traditional stamped steel cages. They are meticulously crafted for non-drive-train auxiliary systems and electric vehicle (EV) components where high speed and low noise are performance mandates.
