Description
SKF PWM Filament Wound Bushing: SKF filament wound bushings are maintenance-free, corrosion-resistant, high performance bushings. The backing consists of high strength glass fibres and the sliding surface is made from PTFE and polymer fibres. Both the backing and sliding surfaces are embedded in an epoxy resin matrix. These materials combine the mechanical properties of glass fibres and the outstanding tribological properties of PTFE and high-strength polymer fibres. The low friction sliding surface does not require additional lubricant. However, the presence of a lubricant offers protection against contaminants and has no negative effect. SKF filament wound bushings are an excellent solution for bearing arrangements that operate under heavy load conditions with low sliding speeds and/or in corrosive environments.
Benefits: High load carrying capacity, corrosion-resistant, very good electrical insulator
