50Pcs Sleeve Bearings, 4X8X4Mm Self-Lubricating Sintered Bronze Bushings

Description: Wide Working Temperature Range - The sleeve bushings are made of sintered bronze, allowing them to withstand a wide range of temperatures. They offer good frictional performance, especially in high-sliding applications, with a small friction coefficient, ensuring durability and mechanically stable operation. Support Function - The wrapped oilless bushings provide a reinforced housing for shafts or fasteners, enhancing stability and support without damaging or jamming the shaft. They also help to reduce the bore diameter or replace worn-out original bushings on wheels. Self-lubricating Properties - Specifically designed for rotating movements, the plain bearings possess self-lubricating performance. This low-friction material reduces the need for additional lubrication, making maintenance easier and more efficient. Versatile Applications - The sintered plain bearings are mainly used in linear applications to guide or reduce friction. They are widely used in various types of industrial equipment, including electrical equipment, household appliances, printing machinery, and machine tools.
