The DU® Cylindrical Bushes - Inch Size, specifically part number 2015 DU-B, 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 under a wide range of loads, speeds, and temperatures, particularly in dry running conditions. The bushings 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. They can be utilized in both lubricated and non-lubricated environments, making them versatile for different operational needs. The maximum dynamic load capacity is 36,000 psi, with a maximum operating temperature of 536°F. The product features a sliding layer composed of PTFE and fillers, supported by a porous bronze sinter layer and a steel backing, ensuring mechanical strength and dimensional stability. The recommended shaft surface roughness is Ra ,â§ 2-16 Oºin, and the hardness should exceed 200 HB for optimal performance.
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.
