SKF developed hub bearing units for active tyre pressure management

SKF developed hub bearing units for active tyre pressure management SKF's wheel bearing arrangement, that provides a passage for air to pass to and from the wheel and tyre assembly, was a crucial element in realising the Michelin Wabco active tyre pressure management system - an innovative enhancement to vehicle safety. The wheel bearing arrangement is the interface between the rotating wheel and tyre assembly and the vehicle's suspension. Hub bearing units - integrated wheel bearing arrangements - are typically sealed to prevent water and dirt to enter the application and to retain the grease that lubricates the bearing. For the new Michelin Wabco system, SKF has incorporated additional special sealing and airway gallery arrangements that allow air to be exchanged between the centralised compressor and control systems and the vehicle's four tyres. Modern hub bearing units come in a range of basic design families. SKF has developed specific sealing and air gallery adaptations for all members of these families. This additional sealing and the airway galleries have been designed and extensively tested to ensure they provide a solution for the Michelin Wabco system that is as durable as conventional hub bearing units. SKF is the world leader in hub bearing units. All major developments in hub bearing units have been pioneered by SKF, from the initial concept of the 1930s to the 1999 "Compact Hub Halfshaft" assembly, developed jointly with GKN Automotive, and the 6th generation unit - with an integrated carrier for the brake disc rotor, announced this year. SKF has continually enhanced and extended this family of products, improving integration, reducing weight and enhancing customer value. Göteborg, February 28, 2001 Aktiebolaget SKF (publ.)
