Ball Bearing Insert-Molded Plastic Gear

Manufacturing Processes & Capabilities

• Precision In-Mold Positioning & Anti-Flash Sealing: Utilizes dedicated mold locating fixtures to securely hold the outer ring of the ball bearing, ensuring strict seal integrity against resin penetration into internal raceways or seal shields.
• Low-Stress Injection & Bearing Geometry Protection: Optimized gate positioning and regulated injection pressure/temperature curves eliminate thermal stress and crushing forces on the bearing, maintaining original internal clearances and rotational smoothness.

Features & Advantages

• Superior Concentricity & Ultra-Low Friction: Integrated insert molding of the gear and bearing eliminates eccentricity tolerances associated with post-molding press assembly, achieving ultra-smooth rotation and low running torque.
• Streamlined Assembly & Enhanced Reliability: Bypasses secondary bearing pressing steps, preventing raceway or ball damage, maximizing assembly yield, and significantly extending component service life in high-speed transmission applications.
