The metal shell of a PTFE-lined bushing is not ideal for applications where water or caustic chemicals are present. In these types of applications, PTFE-lined bushings can rust, corrode, contaminate sensitive areas, and ultimately fail. Since plastic bushings are made solely of high-performance polymers, they offer both corrosion- and chemical-resistance and operate unaffected in those types of environments.
Steel backed PTFE lined bushings is a low cost, general purpose bearing product that provides excellent wear characteristics at high loads, speeds over a wide temperature range.
Designed to be self-lubricating bushings they are rolled bushings composed of a steel backing, for structural strength, with bonded layers of sintered bronze and PTFE for a maintenance free bearing surface.
The thin wall bearing design, excellent performance features, and low cost make this product one of the most popular self lubricating bearings in the industrial global marketplace.
PTFE-lined bushings weigh more than plastic bushings. When using a heavier bushing, no matter what material it is comprised of, more energy is required for the bushing to operate. This can be troublesome, especially in automotive, aerospace, recreational vehicle, and bicycle applications.
In contrast, plastic bushings are lightweight, which helps decrease fuel consumption and carbon dioxide output. The reduced weight can also help reduce carbon dioxide output, lower masses and subsequently, lower energy consumption.
