February 6, 2012—SKF today announced the launch of a new MacPherson suspension bearing unit, which can extend the unit life, leading to an increased overall suspension system lifetime.
The specific technical features of the new bearing unit are:
New seal design that combine's excellent protection against external pollution with low friction torque. Fifty percent less water content when tested against a standard seal, and 20 percent less friction torque.
New ball set designed to increase radial load capacity by 20 percent and lower radial clearance by 40 percent.
Metallic spring seat over-molded inside lower polymer housing to increase resistance against deformation by 50 percent, and stresses by eight percent on composite components.
"To meet the increased performance demands, in terms of higher reliability and increased operating life, SKF redesigned its MacPherson suspension bearing unit, using design for Six Sigma, to withstand higher levels of severe driving conditions," says Andrea Griseri, Business & Product Development Manager for Steering and Suspension, SKF Automotive Division.
Griseri continues, "Today car manufacturers build on platforms that are intended for global markets. This means that the same car models must cope with a wider range of external forces in different driving conditions, especially severe conditions. The MacPherson suspension bearing unit answers these new market requirements, being able to support high load, withstand severe pollution and improve reliability".
With a global footprint of production sites and application/technical centers located in Europe, Asia, and Americas, SKF has the capabilities and is structured to fulfill worldwide automotive market requirements.
