Self-lubricating bearings are bearings that can work without the need for oil. They can use Rongchang high-strength brass as the base. According to the working conditions, holes are machined in the working surface in a certain proportion and filled with solid lubricant. The high-strength copper alloy provides a high load-bearing capacity and the solid lubricant can form a lower friction pair. Under dry friction conditions, we design a pre-lubricating film on the bearing surface to ensure that the solid lubricant is transferred to the dual parts in the shortest time and forms an effective solid lubricating film.

Self-lubricating bearings can Design the refueling mode or the non-refueling mode, mainly depending on the customer's usage requirements.
