Plastic Bushings and the Engineer's Dilemma


The end user of automotive vehicles wants a comfortable drive, meaning low noise and a consistently smooth feel of adjustment mechanisms for the lifetime of the vehicle. A possible choice of a bushing to go into the interior systems of a vehicle are injection molded plastic bushings. This choice will lead your design engineers to a dilemma. Do they choose a tight fit for the bushing to eliminate rattle noise but increase the torque of adjustment mechanisms or a loose fit which provides ease of adjustment but increases rattle?


Even though plastic bushings are a possible choice of an interior bushing, for end-user interior comfort they fall short in key performance areas. With plastic bushings comes the risk for a rattle or high torque, low load capability, and low misalignment compensation.


As an improved solution, NORGLIDE PTFE bushings exhibit the required properties that give the end user their desired comfort. The PTFE material is more compliant than injection molded plastic and can, therefore, be used in interference conditions, without increasing the torque. This means rattle can be reduced without compromising the torque requirements. Also, the metal backing offers high load capability and the PTFE layer is able to withstand the 180°C temperature of paint-line processes.
