Self-Lubricating Bearings
Self-lubricating bearings hold oil in their pores, releasing it under load so they run without external lubrication. Huaxiao delivers self-lubricating bearings as part of our ISO 9001:2015 certified Powder Metallurgy capabilities — from rapid prototyping to high-volume production, with full dimensional inspection and material certification on every order.

What Is Self-Lubricating Bearings?
Self-Lubricating Bearings compacts metal powder in a die and sinters it to bond the particles, forming complex, near-net shapes in one press stroke. Huaxiao’s Self-Lubricating Bearings is ideal for high-volume, tight-tolerance components.
Because the die defines the geometry, features like teeth, hubs and oil grooves are formed directly — with almost no scrap. We add sizing, coining and secondary machining to hit final specs.
