Copper guide graphite coated bushing flange bearing sleeves
This material provides a maintenance free and low friction bearing solution, particularly for high load and intermittent oscillating motion. Solid lubricants within the bronze combine the strength of the bronze with the wear resistance of the grapgite. Applications covered are automotive production lines, water industry, dam gates, platic moulding machinery etc. Different types of bronze alloy can be offered according to the application.
