Needle Thrust Bearing | Image Resource: indiamart.com With different types of bearings available in market, a lot depends on their usage and suitability. If your application asks for great stiffness and high durability, then the needle roller thrust bearings, among the others, are the best choice. A needle thrust bearing has several needle rolling elements, which are controlled by a cage. Where you have minimal axial space, this bearing is used to manage heavy axial loads.
Several heavy applications demand the use of needle roller thrust bearings for they do not occupy much space but only that occupied by the thrust washer. The bearing does not require any raceways; instead it used the adjoining components as raceways; thus, it is known to take less space but offer great dependability. Get to Know Some Intrinsic Characteristics of Needle Thrust Bearing The innate features of needle thrust bearings make them the most sought-after components in industry. You can find their use in a range of applications, such as machine tools, high-pressure pumps, automobiles, industrial machines, and so on. The following are the most important characteristics of the thrust needle bearing. Where you want to manage heavy axial loads and also peak loads, you can do so with needle roller thrust bearings, with a small deviation of the rollers by less than a diameter. These bearings are known for their extended service life, with the tapered rolling elements to not to experience stress peaks while in operation. With the slight design change, the rolling elements change the line of contact. Different Design Variants of Needle Thrust Bearings The application of a needle roller thrust bearing is based on its design variants and suitability. Needle roller bearing and cage thrust assemblies: Where you want a bearing to handle one-directional axial loads, a needle roller bearing, along with cage thrust assemblies, is used. The availability of this bearing in different sizes and dimensions helps its use with raceways in applications, where there are no adjacent components to use as raceways. Needle thrust bearing and a centering flange: This variant has not only cage thrust assemblies but also a centering flange and thrust washer to have the raceways centered radially. Multi-direction needle thrust bearing: The intermediate washers need to be of the same hardness and surface finish like that of a bearing. With changes in the design, you can have a two-directional needle thrust bearing by combining two bearings using raceways, an intermediate washer and cage thrust assemblies. Using Needle Thrust Bearings in Different Applications Variations in sizes, class-type clearance, dimensions, series, and so on make a choosing of a needle thrust bearing quite challenging. You can use the needle bearing catalogue for more information. For longer service life and higher reliability, you can choose the taper roller bearing design, which are largely found in automobiles like cars, buses, light trucks, trailers, and two wheelers.
