Yes. Unlike metal bearings, plastic bearings resist water and corrosion. As plastics have low moisture absorption, it means they will not easily swell or impact the equipment they are used in. Many plastic bearings have PA66 nylon retainers. PA66 does absorb more moisture than many other plastics so for very wet conditions, PE, PP or PVDF cage material can be specified. As plastic bearings can be run dry, there isn’t the problem of lubrication washout.
