The primary difference is the type of retainer used. Radial bearings have a crown retainer, and angular contact bearings have a full retainer.
Radial bearings tend to be more convenient to install and load. Angular contact bearings spin faster and last longer. However, they tend to be harder to install and load. Additionally, there are external factors that can impact the life of an angular contact bearing.
Phenolic is porous and can be filled with oil. This allows retainers made with it to be self-lubricating. On the other hand, Torlon is not a porous material and will not be filled with oil. However, retainers in this material can come with other types of lubrication built into it. Additionally, Torlon handles repeated sterilization better.
A hybrid ceramic bearing will run cooler, last longer, and reduce your chance of equipment failure. It is also a much lighter option than traditional steel. The result is that the bearing experiences less friction and can operate at higher speeds. Another advantage is that ceramic will experience less surface damage. This is because ceramic is much harder than steel, so there are fewer potential threats to the material. Additionally, ceramic does not require as much lubrication as steel.
Choosing the right bearings for your handpieces can be difficult. Fortunately, knowing the answers to some of the most commonly asked questions can help you get started on your search for parts.
