The DU™ Cylindrical Bushes - Inch Size, specifically part number 6530DU, are designed for a variety of industrial applications, including aerospace, agricultural equipment, and food processing. 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. The bushings are also approved for use in interior aircraft applications according to Federal Aviation Regulations FAR 25.853 and FAR 25.855.
The product features a metal backing with a porous bronze sinter layer, which is impregnated and overlaid with a filled PTFE bearing lining. This construction enhances mechanical strength, dimensional stability, and thermal conductivity. The DU bushings are suitable for linear, oscillating, and rotating movements, and can be used in both lubricated and dry applications. Maximum dynamic load ratings and operating temperatures are specified, with a maximum sliding speed and pU factor that vary depending on the application conditions.
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.
