The DU Cylindrical Bushes - Inch Size, specifically part number BB2012DU, 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 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 that enhances mechanical strength and thermal conductivity. The sliding layer consists of PTFE and fillers, contributing to its low friction characteristics. The maximum dynamic load capacity is 36,000 psi, with a maximum operating temperature of 536¬8F. The bushings are available in standard dimensions and can be customized for specific applications.
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.
