In order to be able to rotate high loads without exerting much force, the motion plastics specialist igus has developed the largest xiros polymer slewing ring bearings in the world with an internal diameter of 400 millimetres. This means that users with only 15 newton metres of drive power can move 250 kg of axial load without lubrication. On request igus supplies the bearing fully made from FDA-compliant materials.
In order to be able to move high loads easily by hand, igus has developed the largest xiros polymer slewing ring bearing in the world.
Special customer requests are often the driving force for new innovations at igus. Because what helps one user with a special challenge, perhaps also solves constructive challenges for other customers. One example of this is the largest xiros polymer slewing ring bearing in the world. It has 400 millimetre inner diameter, 600 millimetre outer diameter and 40 millimetre high, which was constructed on the basis of a customer request in the chemical material flow industry. The name xiros stands for dry operating polymer ball bearings, which are characterized by their freedom from maintenance and low friction. For example, a load of 250 kilograms can be rotated with the XXL slewing ring bearing with a low drive torque of 15 newton metres. By dispensing with lubricant and the open design, the customer can flush the bearings daily.
Versatile use from food technology to chemical engineering
Both the ring material and the cage, which holds the rolling elements in the correct position, are made of the abrasion-resistant and chemical-resistant material xirodur B180. The use of glass balls (made of borosilicate glass) ensures excellent chemical resistance. Due to the use of stainless steel balls, the slewing ring bearing is fully made of FDA-compliant materials. It can be used in direct contact with food or medicine. igus supplies the xiros polymer slewing ring bearing on request – as an extension of its comprehensive standard product range of polymer ball bearings, which are available as required in six different ring materials, four cage materials and three ball materials.
