  • Fabric lined bushing
    Patent number: 5417499
    Abstract: A fabric lined bushing is formed by placing a braided liner around a mandrel coating the liner with an adhesive and injection molding an elastomeric bushing material around the adhesive coated braided liner. The braided liner is formed from polyester fibers and polytetrafluoroethylene fibers. Molding the elastomeric material under pressure around the braided liner while positioned on a mandrel tends to stretch the braided liner binding it more tightly to the mandrel and preventing the elastomeric material from penetrating the liner. The interior surface of the bushing is primarily the braided liner material which reduces noise and decreases wear.
