This product processes holes and fills white graphite in its working surface at a certain ratio according to the working conditions. The high-strength copper alloy provides a high carrying capacity and the solid lubricant can form a lower friction pair. Under dry friction conditions, we design a layer of pre-lubricating film on the bearing surface to ensure that the solid lubricant is transferred to the coupler in the shortest time and an effective solid lubricating film is formed. The middle is the thread design.
