xiros® slewing ring ball bearing: rotate axial loads precisely and safely

Largest slewing ring ball bearing by igus for loads of up to 500kg

Special customer requests and wishes are often the driving force for innovations at igus. One example of this is the largest slewing ring ball bearing in the world by igus. It has 400 millimetre inner diameter, 600 millimetre outer diameter and is 40 millimetre high, and was constructed on the basis of a customer request in the chemical material flow industry. xiros stands for dry operating plastic ball bearings, which are characterised by their freedom from maintenance and low friction. For example, a load of 250 kilograms can be rotated with the XXL slewing ring ball bearing with a low drive torque of 15 newton metres. By dispensing with lubricants and due to the open design of the slewing ring ball bearing mounted on ball bearings, the customer can flush the bearings daily.
