The DU¬Æ Cylindrical Bushes - Inch Size, specifically part number 3520DU, 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 can accommodate 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. The maximum dynamic load capacity is 36,000 psi, with a static load capacity of 50,000 psi. The operating temperature range extends from -200¬8C to 280¬8C. The bushings are available in standard dimensions and can be customized to meet specific requirements. They are compatible with both lubricated and dry applications, offering good performance in both scenarios. The recommended shaft surface roughness is Ra ,⧠2-16 Oºin, and the surface hardness should exceed 200 HB.
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.
