Product Spotlight: Cast Bronze Bearings
A lot of the technology we use today is relatively recent, popping up for the first time around the Industrial Revolution and then undergoing refinement and innovation until ending up where it is today. Cast bronze bearings, however, have been used in some form or another for hundreds of years.
Bronze bearings come in all sorts of shapes and sizes, including sleeve bearings, split bearings, flanged bearings, thrust washers, and wear plates. Custom oil grooves, threading, and drill holes are available on certain bronze bearings, as well.
The bottom line is that these are an essential part of many machines, and we just so happen to provide some truly excellent bronze bearings here at Diversified Bronze.
Choosing Cast Bronze Bearings
Knowing which cast bronze bearings to choose depends on the service conditions, the required material properties, and the type of bronze. While not all of these conditions can be known before buying these materials, an accurate prediction will be essential in purchasing the right bronze bearings.
The first thing to consider when determining what bronze bearings may be necessary for a certain machine are the service conditions. According to Copper.org, the following service conditions are the ones that can have the biggest impact on which bearings are the best fit:
- Oscillating motion, especially those that fall short of full revolutions.
- Environments that may prove corrosive to the metal.
- Dirty environments, or environments that may require lubrication.
- Inconsistent supplies of lubricants.
- Machines that experience frequent stops and starts.
- Shafts that can grow misaligned.
Knowing which of these environmental factors may affect your bearings can go a long way toward choosing the right ones.
The metals and other materials in machines also can affect which bronze bearings are most appropriate for a certain project. For example, we may look at any disparity between the hardness of the metals in use, as well as how that may impact the coefficient of friction between those two metals.
Other considerations include the material’s ability to absorb and discard small contaminant particles, its high compressive strength, its high fatigue strength, its corrosion resistance, its low shear strength, its structural uniformity and its cost and availability. Needless to say, we offer a number of bronze bearings that can work for each of these conditions.
Types of Bronze
The final consideration comes in the form of bronze types, of which there are many. Different alloys are better for all of the varying conditions listed above, with different metals helping to add certain qualities to the bronze. Tin bronzes, leaded tin bronzes, high-leaded tin bronzes, aluminum bronzes, and manganese bronzes all perform differently in action, giving each machine exactly what it needs to run as well as designed.
If a business needs any help determining what their needs are from their bronze bearings suppliers, we always are happy to help. At Diversified Bronze, we hold ourselves to a high standard in both service and product quality, especially when it comes to our cast bronze bearings.
