Bronze Plugged Graphite Bushings for Water/Dam Gates: Enhancing Operational Efficiency
Bronze Wear Plate Material, Grease Groove Wear Plates
Grease groove wear plates are used to hold lubricating grease and reduce friction and wear on machinery parts. They typically have grooves machined into them to provide a path for the grease to spread across the surface of the wear plate, thereby extending the life of both the wear plate and the corresponding part. These plates are available in various materials such as bronze and steel, and they can be customized with features like hole patterns, pockets, chamfers, and cutouts to maximize protection. When the use of wear plates with graphite is not an option, conventionally lubricated grease groove wear plates are a good choice . The grooves in these plates provide a path for the grease to spread across the surface, reducing friction and wear, and extending the life of the plates and the corresponding parts.
