The DU® Cylindrical Bushes - Inch Size, specifically part number 2020DU, are designed for a variety of industrial applications including aerospace, agricultural equipment, and food processing machinery. These self-lubricating bushings provide excellent wear resistance and low friction performance across a wide range of loads, speeds, and temperatures, making them suitable for dry running conditions as well as lubricated applications. The bushings are approved to Federal Aviation Regulations FAR 25.853 and FAR 25.855, indicating their suitability for use in aircraft interiors. They can accommodate linear, oscillating, and rotating movements, and are available in standard dimensions, with options for custom designs. The maximum dynamic load capacity is 36,000 psi, with a maximum operating temperature of 536°F. The coefficient of friction ranges from 0.02 to 0.25, depending on the operating conditions. These characteristics make the DU® Cylindrical Bushes a viable option for engineers seeking reliable anti-friction solutions in demanding environments.
Our metal-backed, PTFE-based (polytetrafluoroethy
The metal backing provides mechanical strength, while the bronze sinter layer provides a strong mechanical bond between the backing and the bearing lining. This construction promotes dimensional stability and improves thermal conductivity.
These polymer bearing linings, being predominantly PTFE, offer exceptionally low friction.
