To address Original Equipment Manufacturers' (OEMs) needs for high performance, corrosion resistance and lightweight aluminium or multi-material hinges, Saint-Gobain, producer of NORGLIDE® Bearings and RENCOL® Tolerance Rings, has developed a new range of customisable composite bearings. Combining new design features, leading material advancements and Saint-Gobain's proprietary polytetrafluoroethylene (PTFE) compound liner, NORGLIDE® corrosion resistant bearings are designed with Saint-Gobain's four-fold philosophy of smart design, perfect fit, noise free and long life in mind.
An aluminium encapsulation with a steel support, acts as a cathode to prevent rust, while maintaining the lightweight properties of NORGLIDE Bearings. Innovative scoring exposes the core material when in contact with steel housings, further minimising electrical conductivity issues.
Combining the unique material properties and bearing design ensures that it is the perfect fit to control the amount of conductivity and torque produced during assembly. As such, this allows OEMS to carry out the painting process with ease, without affecting the performance of the bearing. The smart design of the new bearing range presents lightweight, space saving capabilities while the PTFE compound layer minimise any noise issues. Ultimately, this reduces weight and space concerns and operational costs for the OEM, whilst enhancing end user driving experience. In ISO-certified tests, the new composite bearings have proven to offer the highest corrosion protection while simultaneously providing high load capabilities for long life. Results show that NORGLIDE corrosion resistant bearings stand up to salt and moisture conditions well beyond their normal applications and more than any other bearing types on the marketplace. After 1,000 hours in salt spray tests, where galvanized steel or aluminium hinges housed the component, the bearings displayed no red rust at all.
"We have seen a trend for multi-material hinges in the industry, as such, to facilitate this with OEM needs for bearings that are resistant to corrosion without compromising on load capabilities we developed a new range of bearings. The brand of a car can live or die by its ability to perform well throughout alternating weather conditions -- having components that perform well whatever the weather, and load, is essential for reputation and repeat sales. We are confident that our NORGLIDE corrosion resistant bearings will keep the OEM ahead of others in an extremely competitive marketplace and also save them bottom line costs through facilitating the manufacturing process," said Hans-Jürgen Jäger, global Market Manager, Automotive Exterior.
The NORGLIDE® corrosion resistant bearings will be commercially available from November 2015.
