Picture 1.1: The dream of every design engineer: plastic bushings with a predictable service life
Picture 1.2: iglide® plastic bushing laboratory for tribological tests
Picture 1.3: Testing the properties of iglide® plastic bushings
iglide® plastic bushings are made from reinforced fibers and solid lubricants. They have been tested and proven millions of times in many different environments and applications.
igus® engineers develop more than 100 new plastic compounds each year, which are tested in bushing form in more than 5,000 experiments annually. Over the years, igus® has used the resulting test data to build up a comprehensive database on the tribological properties of its plastics.
Today, this database makes it possible for us to assess the expected service life of an iglide® plastic bushing in a specific application. Our experience brings with it peace of mind for our customers.
Based on the results of several thousand empirical tests, we are able to provide reliable information about the service life of iglide® plastic bushings in almost any application. Our test data also enables us to recommend the most suitable shaft material.
No other base material is comparable to thermoplastics in terms of their capabilities. Plastic bushings can be injection molded with lubricants and fiber reinforced. Different plastic blends will cause a bushing to act differently, particularly when it comes to friction and wear behavior.
igus® develops plastic bushing materials that fulfill the maintenance-free requirements of today's design engineers, namely:
Plastic bushings capable of withstanding high loads
Plastic bushings with a low coefficient of friction
Plastic bushings with guaranteed wear resistance
Any disadvantages of plastics can be substantially reduced by material development and bushing design. For example, iglide® plastic bushings are thin-walled. Some iglide® materials feature particularly high heat conductivity. In combination, these factors facilitate rapid heat flow and directly enhance the load capacity of the plastic bushing.
High compressive strength
Good heat conductivity
Low 'creeping' tendency
