Inlaid self-lubricating composite material is a new type of anti-extreme pressure solid lubricating material, by the metal substrate and embedded in the substrate hole or groove in the solid lubricant paste composition. In the process of friction metal substrates bear the vast majority of the load. The solid lubricant film, which is lubricated and firmly adhered and uniformly covered on the friction surface, is greatly reduced in friction and wear by the solid lubricant in the friction, hole or groove to the friction surface. With the friction, the embedded solid lubricant is continuously provided on the friction surface, ensuring good lubrication during long periods of operation.

                              

                                             Oil-free bearing copper sleeve

This type of product is a kind of oil-free bearings, oil-free bearings are not refueling, but in the absence of fuel conditions, because of their own self-lubricating properties, but also a good job, so generally in the work difficult Refueling maintenance, the use of this type of oil-free bearings can be better than ordinary bearings, but if the refueling can be maintained from time to time, then the product life can be more extended.
