Two component polymer ball bearing
Ball bearingigus® GmbH
Have you ever seen a plastic ball bearing where the rings are made of two materials? This two-component bearing is intended for applications that require high speeds and reduced noise levels. So what is the advantage? The blue material is highly wear-resistant and makes the ball bearing much quieter. However, this quieter material is also soft, making the bearing less stable and prone to breakage at high speeds. That solution was to mold the soft material in a hard shell, ensuring quiet operation with great durability at high speeds.
