The DU™ Cylindrical Bushes - Inch Size, specifically part number 2215DU, are designed for a variety of industrial applications, including aerospace, agricultural equipment, and food processing machinery. 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 constructed with a metal backing, a porous bronze sinter layer, and a PTFE-based bearing lining, which enhances mechanical strength and thermal conductivity. They are approved for use in interior aircraft applications according to Federal Aviation Regulations FAR 25.853 and FAR 25.855. The product is available in standard dimensions and can be customized for specific requirements.
Engineers should consider these bushings for applications requiring reliable performance in linear, oscillating, and rotating movements, particularly in environments where lubrication may be limited or absent.
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.
