Steel-to-PTFE composite self-lubricating rod end knuckle bearing and manufacturing method thereof

The invention discloses a steel-to-PTFE composite self-lubricating rod end knuckle bearing and a manufacturing method thereof. According to the steel-to-PTFE composite self-lubricating rod end knucklebearing and the manufacturing method thereof, a material with the PTFE self-lubricating function is used in the extruded rod end knuckle bearing, extruding is carried out by adopting a self-extrusiontechnology, the maintenance-free effect of a product is achieved through the self-lubricating performance of a PTEF composite, so that the service life of the product is prolonged, the product is suitable for occasions with large load, limited space, troublesome assembly and disassembly, inconvenient replacement and inconvenient lubrication, and compared with an assembly type steel-to-PTFE composite rod end knuckle bearing, the steel-to-PTFE composite self-lubricating rod end knuckle bearing has the advantages of being the same in using performance, lower in cost and capable of flexibly adjusting backlashes or the mom
