The DU™ Cylindrical Bushes - Inch Size, specifically part number 80100 DU-B, are metal-polymer anti-friction plain bearings designed for a variety of industrial applications, including aerospace, agricultural, and construction equipment. 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 standards FAR 25.853 and FAR 25.855, indicating their suitability for interior aircraft applications. 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, and they can operate effectively in temperatures ranging from -200°C to 280°C. The product features a porous bronze backing and a PTFE-based sliding layer, contributing to its mechanical strength and low friction characteristics.
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.
