The DU¬Æ Cylindrical Bushes - Inch Size, specifically part number 5050DU, 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, particularly in dry running conditions. They are suitable for linear, oscillating, and rotating movements and are approved for use in interior aircraft applications according to Federal Aviation Regulations FAR 25.853 and FAR 25.855. The maximum dynamic load capacity is 36,000 psi, with a maximum operating temperature of 536¬8F. The bushings can accommodate sliding speeds up to 1,000 fpm and have a coefficient of friction ranging from 0.02 to 0.25, depending on the operating conditions. The product is available in standard dimensions and can be customized to meet specific requirements. The construction features a metal backing, a porous bronze sinter layer, and a PTFE-based bearing lining, ensuring dimensional stability and thermal conductivity.
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.
