Series Q-Single Row Ball Slewing Bearing-External Gear

The slewing bearing rolling elements are usually separated by individual nylon spacers. This structure can maintain the smoothness of the movement, and the price is low, so it is widely used. Special applications need to use special ball or roller isolation blocks, such as copper, aluminum and other high-temperature isolation. Generally, bearings installed on horizontal shafts or continuously rotating generators and slewing bearings used in occasions with high requirements for positioning and reliability can use strip combined cages to keep the rolling elements in the correct position. Circumferential position, higher reliability.
