There are a great many patents that describe the use of PTFE in various polymer systems, blends, and composites and we will not describe all of them.
Polymers can withstand heavy loads and high speeds, making these types of bearings ideal for applications requiring high PV. The versatility of plastic bearings makes them ideal for both low and high load applications. Self-lubricating chains, also referred to as lube-free chains, are commonly found in both roller chain and conveyor chain varieties, with specialty self-lubricating chains also available. These chains utilize a bush made of an oil-impregnated sintered metal or plastic to provide continuous lubrication to the chain during drive, eliminating the need for further lubrication. Every year, igus® engineers conduct more than 5,000 tests under real-world conditions inside our 41,000-square-foot test lab to ensure each self-lubricating material lasts longer and performs better than metal components. They also develop more than 100 new plastic compounds and polymer blends every year. Watch the video or click the button below to learn more about our test lab.
