JDB Solid Lubricant Inlaid Bearing

The so-called no oil supply refers to the need for no or minimal refueling. Our research goal is to ensure that bearings can still perform well under such working conditions and extend their service life as much as possible. The basic working principle of self-lubricating bearings is that during the initial operation stage, the solid lubricant on the surface of the bearing forms a transfer film due to mutual friction and covers the grinding parts, ultimately forming a solid lubricating film to achieve self-lubricating. It blocks direct contact between the workpieces, effectively protecting the grinding parts and extending the service life of the bearing and workpiece.
