Engineering plastic bearings used in automobile accelerator and brake pedal mechanism

Automobile accelerator and brake pedal are the most frequently used mechanisms by drivers. Therefore, the flexibility and durability of the accelerator and brake are particularly important. Before the 1970s, automobile manufacturers used oily-powder metallurgy bearings to improve the rotation situation. However, the oil in the pores of the oily-powder metallurgy bearing is highly volatile that leads to the bearing failed easily. Later on, appearance the three-layer composite self-lubricating bearings replaced oil-containing powder metallurgy bearings gradually as the best design at that time. Although three-layer composite self-lubricating bearings are still widely used in accelerator and brake pedal swing mechanisms, more and more automotive design engineers adopt engineering plastic bearings into their designs along with the continuous development of the technology of  high-performance engineering plastic bearing material. EPB13 engineering plastic bearings use high-performance engineering plastics as the basic raw material and implant high-strength fibers and special solid lubricant into the raw material. It makes EPB13 bearings have sufficient pressure resistance and wear resistance, ensuring long-term service life. With this solution, no need to worry about noise or intermittent jamming of the accelerator and brake swing mechanism, or even the rust problem after long-term shutdown.
