Saint-Gobain Performance Plastics is offering the Norglide range of lightweight low-friction composite bearings for bicycle components including headsets, pedals, brakes and drive train.
In headsets, the Norglide composite bearings provide a lightweight low-friction alternative to conventional sealed roller bearing elements.
Comprising a fluoropolymer friction surface with a rubber backing, the bearings are claimed to be deceptively simple in appearance but incorporate technologies that enable them to exceed the performance of conventional bearings while requiring no maintenance.
Norglide bearings are equally beneficial in bicycle pedal assemblies, where they can be used in place of axle-shaft rolling element bearings and plastic bushings.
In these applications, the Norglide products share the inherent resistance to corrosion offered by their plastic counterparts.
In addition, however, they are free from the risk of performance degradation that, with plastic components, often results from the absorption of moisture.
For bicycle braking systems, Norglide bearings find applications in the brake levers, where they provide a low-clearance, low-friction upgrade for conventional lever pivots, and in cantilevers, where they offer a high-performance corrosion-resistant option for brake pivots.
A low-friction cylinder, flange or washer with an interference fit can be used to provide the braking system with the perfect feel, according to Saint-Gobain Performance Plastics.
In all applications, Norglide composite bearings can be customised to accurately match the user's requirements by adjusting their geometry and the composition of the fluoropolymer material used in their construction.
In addition to Norglide composite bearings, Saint-Gobain Performance Plastics offers Norslide cable liners and Rencol tolerance rings.
