These products routinely blow the competition out of the water with impressive performance under the harshest conditions. In addition, the company provides excellent customer service which makes them a very dependable partner in this rapidly evolving industry.

Water-Lubricated Bearing Systems

In the past, ships would break down quite often due to mechanical issues with the shaft and bearing systems. Duramax Marine has changed all that by elevating the standards of water lubricated bearings. The company injects millions of dollars into high-level research. The results of the studies are used to create rubber compounds that produce impressive performance in real world applications. Competitors have been left lagging behind. The most demanding clients, including the US Navy, choose Duramax products for the vast majority of their surface ships.

Johnson Cutless Bearings

This breakthrough product line is the marine industry's most favored water lubricated bearing. They have proven themselves to be reliable components in all kinds of vessels. Duramax Marine was the first to come up with cutless bearings through this line and it still stands as the only authentic product worthy of the label. Others have attempted to mimic the technology but all have come up short in terms of performance.

Johnson Demountable Stave Bearings

One of the challenges with large shafts and propellers is that they often have to be removed during maintenance and installation of the bearings. However, Johnson Demountable Stave Bearings changes all that by providing an ingenious system that allows each piece to be installed or removed quickly and easily. This is of enormous benefit as the maintenance cost in both time and money is reduced significantly. These heavy nitrile rubber staves can be slid on perfectly fitting grooves so vibration is minimized. This prevents the shaft from wearing out and prolongs its service life. It is possible to have the staves custom-built for optimum alignment and fit.

Applications: Commercial Marine

Duramax products can be found in many of the commercial vessels sailing today. Marine engineers depend on them to mitigate wear and tear which makes their job much easier. Any breakdown will cause costly shipment and travel delays so keeping things in top shape is always a priority. The company employs a team of professionals who have a deep understanding of what commercial fleets face on a daily basis. The team works tirelessly to improve the products and solve any new problem that comes along. Aside from research and development, they are also on hand to provide valuable support in times of need. If there is a maintenance issue that requires their technical expertise, the team will always be willing to give all-out assistance.

The proprietary rubber formulation of Duramax Marine stays true to the company's name. It has demonstrated excellent durability time and time again. The nitrile rubber protects the shaft from damage which makes it superior to alternatives like hard surface bearings. With the business at stake, commercial ships prefer Duramax products every time.

Applications: Recreational Marine

Recreational vessels range from personal watercrafts to large yachts. These can cost quite a sum and so the investment should be protected through proper care. That's why those in the know turn to Duramax Marine products for precision parts and exceptional services. Johnson Cutless water-lubricated rubber bearings dominate in this segment with interior diameters ranging from 3/4" to 6-1/2". Customers can choose between naval brass and non-metallic sleeves. Round bore housings, meanwhile, will be best served by Johnson Demountable Stave Bearings which can fit shaft diameters of at least 2-1/2".

Using Duramax Marine Bearings

Every piece of a boat is important. From the zinc anodes to the navigational equipment, everything needs to function as intended. It is important, then, to always make sure that the parts you buy come from a name that you can trust. If you are in the market for marine bearings, you should not overlook the product’s importance. While perhaps a minor part of your operations, they should still be treated as a vital part of your ship. If you want to purchase the best, it is wise to consider Duramax as your first, best choice.

Duramax marine bearings are actually created with several purposes in mind. In addition to basic propulsion applications, they are also marine bearings that are designed to work with the rudder and in industrial pumps. The variety of workable purposes can help many boat owners, especially those that are looking for something of an industrial grade; the multiple applications can allow the owners to not only trust the craftsmanship being their bearings, but to purchase the items as needed under a single brand name. This can be quite a time savings, especially for those that manage the care of multiple vessels.

The craftsmanship of these marine bearings is really second to none. Not only are they designed with the utmost precision, but they are specially crafted in such a way that the nitrite rubber will pass U.S. Navy clearances when fit in the shafts. These pieces are designed with the needs of consumers in mind, especially in terms of their non-vibration specifications. The pieces are also incredibly clean, leading to a non-polluting state that may ease the consciences of those that are worried about their ships’ environmental impact. With a solid design that is both friendly to consumers and the environment, it is easy to see why these bearings are so popular.

The Duramax marine bearings are also relatively easy to purchase. Unlike some brands, there are actually many ways to get hold of the product. Not only are distributors and agents available throughout the world, but it is entirely possible to find the units needed at a moment’s notice. Standard bearings are almost always in stock, but it is also possible to order custom units to fit an unusual need. Whether you need a single piece to outfit a single ship or dozens to take care of a full fleet, Duramax can provide the necessary bearings.

If you are in the market for marine bearings, you should certainly take the time to look at Duramax. There are several bearing models available, and custom orders can always be taken. When taking care of a boat of any type, it is always important to make use of parts that you trust. From the smallest boats on a lake to ships on the major shipping lanes, having the right parts is a necessity. Marine bearings may not be the most important piece of the ship, but having the right parts can lead to a better, more profitable voyage.

Understanding Stave Bearings

There are several possible arrangements for shafts and bearings.  The most common arrangement involves having a bearing with a fixed portion surrounding the majority of the shaft; the fixed portion may consist of either one or two pieces.  A stave bearing is different because instead of just one or two parts that surround the shaft, it features a system of axial staves to provide support.  A stave bearing typically has many such axial pieces.

Applications for Stave Bearings

Stave bearings are generally used in nautical applications and are most commonly associated with propeller shafts.  This is because this type of bearing holds up well under the conditions that go along with boat propulsion: high loads and relatively low speeds.  In addition, a stave bearing can easily be adapted to be used in water, which makes it a perfect match for outboard motors.

Stave bearings are also commonly used on rudder shafts.  This is because motion for this component of a watercraft consists of rotation that is both reciprocating and intermittent, instead of continuous rotation in only one direction.  Ball bearings tend to fail more often when used with rudders.

Materials Used in Stave Bearings

Because stave bearings historically contained some wooden components, the choice of wood used had to be one that could resist softening and swelling as well as actual rotting.  In practice, tropical hardwoods were well suited for this application, but modern stave bearings frequently feature composite materials such as polyester resin in place of wood.  Nitrile rubber is another popular material used in stave bearings.

Duramax Marine for Quality Shaft Seals and Bearings

Duramax Marine is a quality supplier of a variety of essential items for the boating enthusiast.  Johnson Duramax specializes in shaft sealing systems and bearings as well as cooling fendering systems.

Shaft Sealing Systems

Duramax Marine produces a wide array of shaft sealing systems. The manufacturer has made it a priority to have their sealing systems fit a large range of different sizes of shaft.  From the Johnson stuffing box, a traditional solution, to the innovations inherent in the Duramax system for sealing shafts, this supplier will have the products needed to keep most kinds of watercraft in tip-top shape – or ship-shape, as they say in the boating industry.

Bearings

Duramax bearings are made of water-lubricated rubber and have proven a popular choice by both casual boaters and professionals in the marine industry.  The rubber is made of a specially crafted nitrile material and is molded against the shaft in a way that fits with the clearances established by the U.S.  Navy.  Duramax bearings are highly variable and depending on the type chosen, can be used not just for boat propulsion applications but also in rudders and industrial pumps.

In addition, Duramax bearings have features that dampen vibrations and cause grit and abrasive particles to be washed away from the shaft, thus lengthening the life of the bearing.  Perhaps best of all, Duramax bearings are available in both stock sizes and custom-order sizes that can be used in a variety of specialized situations.

Duramax Marine is committed to both quality and innovation.
