Application features:
It is especially suitable for rotational movement, swaying motion under heavy load and low speed, and parts that often open and close under load and are not easy to form fluid lubrication. It can be used for a long time without refueling and maintenance under boundary lubrication conditions, and refueling in the process can further extend the service life of the bearing. The plastic layer on its surface can leave a certain margin during shaft sleeve forming processing, and can be processed by itself after pressing into the hole to achieve better assembly size. At present, it is mainly used in metallurgical machinery, mining machinery, water conservancy machinery, automobile chassis, construction machinery, agricultural machinery, steel rolling machinery, etc.
