Products - Back Plate

Back plate also known as the seal plate. This plate connects the bearing housing to the compressor housing, and acts as a retaining device for the thrust bearing system. The back plate serves as a sealed barrier, which prevents compressed air from entering the bearing housing. Seal Plate are mainly of aluminium, these components must be very precise in dimensions to ensure a perfect clearance is found between surrounding components to ensure the perfect seal.
