EPB5Z Engineering Plastic Bearings Applied in Automobile Throttle

The vehicle determines the load of the engine and controls the pulse width of the fuel injection and the ignition timing according to the size of the throttle during idling and driving. Control flap controls the size of the intake air through the sensor to promote the power. The throttle gets dirty easily, mostly caused by poor air and oil quality, also can be carbon deposits generated during the combustion of gasoline. The throttle will be infected by the negative pressure and cause a bad closure. It leads to the increase of intake air volume and the errors of the signal transmission, and causes excessive fuel consumption and engine idling jitter. In addition to the pollution of the inner wall of the valve body will cause those problems above, the failure of the bearing that supporting the rotation of the throttle is also a factor which cannot be ignored.

The traditional design of the throttle swing mechanism is to use metal rolling bearings on one end and metal sliding bearings on the other end. However, due to the poor dirt-resistance of these bearings, it is easy to cause the throttle valve to rotate in difficulties, resulting in problems of vehicle acceleration and idling jitter. EPB5Z engineering plastic bearings have excellent wear resistance, temperature resistance and corrosion resistance, and become the experts in solving the throttle stuck problems. The wear resistance of EPB5Z bearings has been modified on the basis of high-functional engineering plastics. The wear resistance of EPB5Z bearings has been greatly improved on the basis of retaining the original bearing capacity and corrosion resistance which meet the needs of throttle application. EPB5Z bearings show excellent durability whether they are worn against metal shafts, or against friction with PPS + GF30 plastic shafts, even operating in oily and dirty throttle.
