Beyond Conventional Constraints: The DU Bushing Advantage in High-Stress Rotating Systems
Industrial rotating assemblies have long been constrained by a fundamental dilemma: achieving low friction without compromising load capacity. Traditional plain bearings require continuous lubrication, while self-lubricating alternatives often sacrifice strength for convenience. The DU bushing—a metal-polymer composite plain bearing—has emerged as the definitive solution that reconciles these opposing requirements. Unlike conventional bronze bushings that depend on external lubricants, DU-type composite bushings integrate a PTFE-based sliding layer with a porous bronze interlayer and steel backing, creating a self-lubricating system that maintains structural rigidity under extreme loads.
