When ships need a high performance stave bearing, the professionals turn to Duramax Marine. The company produces the popular Johnson Demountable bearing system which is known for its toughness and simplicity. Each piece is precision-tooled to create an exact fit inside the round-bore housing. They lock in place forming a cylindrical pattern that guides shafts and protects them from excessive wear. These keystone-sided molded solid nitrile staves are considered as the best water-lubricated system in its class.



Thanks to the accuracy of the measurements, the staves are able to reduce resonant vibration which consequently enhances the ship's stability. Among the notable features of this system is the quick release design. This allows the maintenance crew to replace the bearings as needed without having to withdraw the shaft. What's more, the replacements for these are so much more affordable than traditional bearings at half the price.



Exceptional Fit



No matter how good a stave bearing is, it will not perform well if it is ill-fitted to the shaft journal. Duramax Marine understands this which is why every piece goes through a rigorous fitting process to get the measures just right. Only after the desired clearance is achieved will the staves be given the thumbs up for packaging and shipping. Computer controlled machines ensure that the system conforms to the exact internal diameter for the housing. The staves are put together inside a comparably sized tube at the factory for testing. The use of compression head results in an extremely precise fit. After this, the diameter is measured to verify if the goal has been achieved. The engineers take no chances as small flaws can be magnified in harsh environments. Every inch is inspected and all the data gathered are recorded for the client's guidance.



Hydrodynamic Design



Effective water lubrication happens only when the design is done just right to take advantage of the movements under the surface. When the shaft turns faster than a meter per second, it creates a hydrodynamic water wedge which is instrumental in isolating the shaft from the bearing so that their surfaces don't touch. The parallel grooves along the inner diameter of the demountable system forms channels through which the water passes continuously. This thin film of liquid is enough to reduce abrasion and prolong the life of the shaft. The grooves also serve as a convenient disposal system for any buildup of harmful chemicals.



Hassle-free Installation



The sides are molded in a keystone shape for a good reason. It allows each piece of the stave bearing to fit securely into place with the bond reinforced by the friction between their surfaces. The identical staves are simply set inside the round bore housing until they form a complete circle. The installation of a compression head comes next for the purpose of exerting force along the length of the system. This locks all the pieces in and ensures that the sides will not snap out. The nitrile rubber surface goes through a controlled deformation until the final desired configuration is achieved. Withdrawal is just as easy and can be achieved piecewise without disassembling the whole shaft, resulting minimal downtime.



Other Benefits of the Johnson Demountable Bearing



Aside from providing excellent water lubrication, prolonging the life of the shaft, and minimizing vibrations, the system provides multiple other benefits. These include flexibility through interchangeable pieces and uniformity of journal size all along the shaft. The materials and design are also responsible for drastically reducing electrolysis and its harmful effects. The system is priced competitively and its ease of handling is an added boon to the customer. All these make the Duramax Marine Johnson Demountable Stave Bearing the ultimate solution for round bore housings.
