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.
