Thrust Roller Bearings
Thrust Roller Bearings are used for many industrial applications. They are able to handle heavy axial loads and high rotational speeds. They are also ideal for agriculture applications. In addition, they have a low moisture absorption and are also rust and corrosion resistant. The bearings are available in various shapes and sizes.
Thrust roller bearings come in a wide variety of materials. Most are made of stainless steel. However, they can also be manufactured from chrome steel. While the bearings are durable, they must be taken care of. Misalignment of the shaft and the raceway can lead to excessive vibration. Moreover, contaminants can damage the bearings. For example, the dirt and burrs on the shoulders of the shaft can cause misalignment. To prevent the bearing from deteriorating, it is important to clean and filter the lubricant.
Thrust roller bearings are designed to be self-aligning. When they are not, they will not function properly. In addition, they are very lightweight. These bearings are suitable for heavy duty applications such as machine tools, pumps and high pressure pumps, agriculture machinery, electronics, and tribological applications.
In addition to their high load capacity, the bearings are also very rigid and provide a very low coefficient of friction. It is possible to choose between tapered and cylindrical roller thrust bearings. Tapered roller thrust bearings are designed to evenly distribute the load between the rollers. There are also single direction and double direction versions of these bearings.
Cylindrical roller thrust bearings have a single row of rollers and a triple row of rollers. This type is recommended for axial load capacity. A double direction version is a good option when you have a heavy axial load to support. You should use a cylindrical roller thrust bearing when your application is not suited for radial loads.
Spherical roller thrust bearings are available in a wide range of sizes and capacities. They are ideal for a variety of applications, including planters, seeders, pumps and power take-off units. Additionally, they have a low grease limiting speed of 80 to 1,600 rpm. Another benefit of spherical roller thrust bearings is the ability to allow for angular misalignment. Unlike ball and roller thrust bearings, spherical roller thrust bearings do not have a cage.
Spherical roller thrust bearings also have a high load rating density. This means that they are able to withstand more axial load capacity than other bearings. Hence, they are used to handle heavy loads in confined spaces. Compared to the other types of bearings, spherical roller bearings are more expensive. But the advantages of these bearings are worth the expense.
Spherical roller thrust bearings can be manufactured from a wide range of materials. These include metal, ceramic, and plastic. Among the most popular materials are steel and stainless steel. Other common materials are rubber and plastic. If the application calls for a bearing that is corrosion-resistant, consider a bearing that is made from ceramic. Alternatively, you can opt for a bearing that has a brass or steel cage.
