Cross Roller Slewing Ring

The cross roller slewing ring has the same structure as the single row type. It is mainly made up of two rings and a row of rolling elements.The product is also widely used inside large crane and other construction machineries.

But there are two raceways in both inner ring and outer ring. The cross section of the raceway is linear type. The roller of the slewing ring is column type and each two adjacent rollers are cross arranging. Therefore, half of the rollers bear the upward axial force and the rest bear the down forward force. The column type roller features linear contact with raceway and little fraction coefficient. Linear contact can enhance its radial load capacity to bear heavy load and impact force. Little fraction coefficient can help the bearing fulfill high speed rotation.
