At the International Suppliers fair (IZB) in Wolfsburg, Germany from 18 to 20 October 2016, SKF will announce the launch of a new product designed to offer greater durability, improved comfort and reduced noise and vibration in automotive suspension applications.  

The spring insulating suspension bearing takes SKF’s robust, proven main suspension bearing unit (MSBU) technology and incorporates a polymer spring that is mechanically and chemically bonded to the lower bearing washer. 

The spring insulator plays a critical role in automotive suspension systems, damping road vibrations that pass from the spring, through the bearing and into the passenger compartment. Conventional spring insulators are installed separately from the MBSU. 

This approach creates a potential failure point in the vehicle suspension, since the insulator is susceptible to damage due to the ingress of dirt and contamination between it and the bearing. 

The new spring insulating suspension bearing eliminates this point of weakness by building the bearing and spring insulator as a single component, with high strength chemical bonding used to connect the spring to the bearing. Additional optimisation of the bearing geometry ensures a secure mechanical connection between the two elements. 

For manufacturers, the spring insulating suspension bearing offers further advantages, reducing the number of components required in the suspension system and simplifying assembly to reduce total suspension cost. The material selected for the spring element can be adapted to suit the precise requirements of the application, and SKF can offer a wide range of material options, all optimised for high volume manufacturing using injection moulding. 

SKF has applied for no less than three patents covering innovative features of the new design, including the spring material, insulator design and fixation technology. Prototype units are already undergoing evaluation by leading Automotive OEMS.
