Our graphite round flange bushing is the perfect solution for projects where lubrication cannot easily be provided or where conventional lubricants may carbonise. The design of oil feeding systems is time-consuming and expensive – The use of our oilless bearings can greatly reduce costs of maintenance and oil as it removes any need for such a system.
