The DU Cylindrical Bushes - Inch Size, specifically part number 4520DU, are designed for a variety of applications including aerospace, agricultural, construction, and medical equipment. These self-lubricating bushings provide excellent wear resistance and low friction performance across a wide range of loads, speeds, and temperatures, particularly in dry running conditions. The material is also suitable for lubricated applications, making it versatile for different operational environments. These bushings are approved to Federal Aviation Regulations FAR 25.853 and FAR 25.855, indicating their suitability for interior aircraft applications. They can accommodate linear, oscillating, and rotating movements, enhancing their applicability in various mechanical systems. The product is available in standard dimensions and can be customized to meet specific design requirements.
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.
