The DU® Cylindrical Bushes - Inch Size, specifically part number 3030 DU-B, are designed for a wide range of applications including aerospace, agricultural equipment, and food processing machinery. These self-lubricating bushings provide excellent wear resistance and low friction performance under various loads, speeds, and temperatures, making them suitable for dry running conditions. The material is also appropriate for lubricated applications and can accommodate linear, oscillating, and rotating movements. The bushings are approved to Federal Aviation Regulations FAR 25.853 and FAR 25.855, indicating their suitability for interior aircraft applications. They are available in standard dimensions and can be customized to meet specific project requirements. 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 operating conditions. The product is compatible with various lubrication methods, including oil, grease, and process fluids.
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.
