Non-metallic cages play a vital role in rolling bearings, not only isolating the rolling elements and keeping them in position, but also reducing friction by guiding the rolling elements in the right orbit, thus extending the life of the bearing.
The characteristics of the non-metal cage of Hebei Bearing Industry Technology Research Institute are mainly reflected in its material and performance. The materials of non-metallic cage mainly include nylon, phenolic tape, polytetrafluoroethylene and other polymers and composite materials. These materials have good strength and elastic matching, as well as excellent sliding properties. In the relative movement with the lubricated rolling element surface, only a small friction is generated, thereby reducing the heat and wear of the bearing, even in the absence of lubricants can maintain a certain movement characteristics, to ensure that the bearing runs for a short time without damage.
