Oil free bushings, also known as self lubricating or oiless bushings, are bearings that do not require external lubrication to function properly. These bushings are made of materials designed to self-lubricate, such as metal polymers or composite materials, which reduces friction and wear on the bearing surfaces.

The development of oil-free bushings dates back to the 1930s when the first self-lubricating bearings were introduced. However, it was not until the 1960s that the use of composite materials in bearings became prevalent. In the 1980s, the development of metal-polymer bearings, which combine the properties of metal and polymer materials, further improved the performance of oil free bushings.

Oil free bushings benefit by eliminating the need for external lubrication, which reduces maintenance costs and saves time. Additionally, these bushings do not leak oil, eliminating environmental concerns and keeping the working area clean. Oil-free bushings also operate silently, reducing noise pollution in the working environment. Oiless bushings are crucial in various industries, including aerospace, automotive, construction, medical, and manufacturing.

Today, oil-free bushings continue to evolve with new materials and designs that offer better performance and longer service life. They are essential to many industries and have revolutionized how machines and equipment are designed and maintained.
