The DU¬Æ Cylindrical Bushes - Inch Size, specifically part number BB0808DU, 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, 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 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 feet per minute and have a coefficient of friction ranging from 0.02 to 0.25, depending on the operating conditions. They are compatible with both lubricated and dry applications, offering versatility in various environments. The recommended shaft surface roughness is Ra ,⧠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.
