The world's first self-lubricating metal polymer sliding bearing DU? That is, PTFE composite bearing, which we are used to calling it, was designed by the creator to meet the application pain points of many historical products:

The structure is composed of rigid steel or corrosion-resistant bronze backing (DU-B), which can provide ultra-high mechanical strength, while the porous sintered bronze interlayer is impregnated with a uniform mixture of PTFE and lead, which can provide low friction and high wear resistance.

Du? The low friction of the bearing reduces the power loss and improves the energy efficiency, while the wear-resistant bronze layer prolongs the service life. Because of self-lubrication, bearings need little maintenance. However, they can also be used with lubricating oil to prevent shaft/bearing sticking that may occur under boundary conditions. All these make this bearing a classic, confiscate it and lead the product research and development direction in the industry!
