The DU® Cylindrical Bushes - Inch Size, specifically part number BB1212DU-B, are designed for a variety of applications including aerospace, agricultural, construction, and food processing equipment. 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. They are suitable for linear, oscillating, and rotating movements and are compliant with Federal Aviation Regulations for interior aircraft applications. The maximum dynamic load capacity is 36,000 psi, with a maximum operating temperature of 536°F. 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. The recommended shaft surface roughness is Ra ,⧠2-16 Oºin, and the hardness should exceed 200 HB. These characteristics make the DU® Cylindrical Bushes a reliable choice for engineers seeking durable and efficient bearing solutions in demanding environments.
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.
