The DU¬Æ Cylindrical Bushes - Inch Size, specifically part number BB2022DU, 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. 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 machinery. The product is available in standard dimensions and can be customized to meet specific design requirements. Engineers considering this product should note its maximum dynamic load capacity of 36,000 psi and a maximum operating temperature of 536¬8F. The DU¬Æ bushings are engineered for both unhardened and hardened shaft surfaces, with recommended surface roughness and hardness specifications to optimize 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.
