The DU,Ñ¢ Cylindrical Bush 18DU12 from GGB is a metal-polymer anti-friction plain bearing designed for a variety of industrial applications, including aerospace, agricultural, and construction equipment. It features self-lubricating properties that provide excellent wear resistance and low friction performance across a wide range of loads, speeds, and temperatures, particularly in dry running conditions. The bushing is suitable for linear, oscillating, and rotating movements and is 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 bearing can accommodate a maximum sliding speed of 1,000 fpm and has a coefficient of friction ranging from 0.02 to 0.25, depending on operating conditions. The recommended shaft surface roughness is Ra ,⧠2-16 Oºin, and the surface hardness should exceed 200 HB. This product is available in standard dimensions and can be customized to meet specific design requirements.
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.
