Bearings should be constantly greased and dust caps act as a reservoir of grease. The main purpose of the Super Lube Dust Cap is to provide maximum lubrication to the components of the hub and protect them from grime, dust and other contaminants. When you service your trailer wheel hub, don't forget to fill in the dust cap reservoir with grease as a lack of grease will wear your bearings out rather quickly.
The Super Lube Dust Cap acts as a source of grease for the trailer wheel hub and it also keeps the grease from getting away from the bearings. It keeps dust and other particles away from the hub and grease, preventing it from getting clogged. This dust cap is a press-on type and fits easily with a 'snap'. It comes with a rubber grommet for additional protection. Made of zinc, this dust cap resists corrosion.
