  • Speed limitations | SKF

    The maximum speed of a bearing can be increased by the use of a nylon or phenolic cage provided a suitable lubricant is used. The use of ceramic balls will increase bearing speed by up to 40 percent but ceramic balls also reduce the load capacity of a bearing as the harder ceramic balls cause an increase in stress on the bearing rings.
