Many Uses of Needle Thrust Bearing in Different Applications in Industry

The oscillatory movements of a machine are well supported by a bearing, especially a needle roller bearing. For the purpose, these bearings undergo improvisations in regards to design, series, dimensions and shapes to manage loads, both radial and axial at high speeds. The latest developments in technology has brought in several changes in the designs of needle thrust bearings to make them suitable for applications that demand high performance under unfavorable conditions.

What Makes Needle Roller Bearings Distinguishable?

A needle roller bearing has its significance in supporting heavy axial loads and their compact design helps them get accommodated even in the minimal space; thus, avoiding the use of large and heavy bearing units, with ring washers. The advantage of these bearings lies in providing compact solutions to the scarcity of space. Needle thrust bearings are preferred to general bearings for their high rigidity and extended service life. 

The variations in design, series, dimensions and class clearance make them highly preferred and used bearing type in automobile and other heavy industrial sectors. The needle bearing with cage assemblies and central flanges are the some of the design variants you can in the needle bearing catalog. There are also needle roller bearings, with taper roller bearing design, which are best applied for managing radial and thrust loads. 

They occupy less space and can be multiplied if the application asks for greater load-carrying capacity. The bearing unit comes without any ring raceways to save its compactness. In case of any need, it uses the adjacent components as ring washers. 

You can have the machine look very compact using a needle thrust bearing, but at the same time, it offers great accuracy supporting heavy loads at high speeds. Moreover, the minimum oscillatory angle helps the roller overlap the position of nearby roller; thus providing adequate lubrication. Hence, the bearing has found its way in a number of applications like compressors, pivots, high-pressure pumps, and machine tools.

Get to Know Some Integral Features of Needle Thrust Bearing

You can find this bearing typically in two variants and they are single-row and double-row bearings. They are available with cage assembles, with a shaft and housing unit. The following are a few important features of this bearing. 

• Accommodates less space: You can have a needle thrust bearing offering minimum space solutions. With a drawn-cup needle thrust bearing, you have low-cross section to make-up space scarcity. 
• High stiffness: The number of rollers with small diameters of minimal oscillatory angle but high rigidity, which ensures better performance. 
• Easy maintenance: You can have easy maintenance of this bearing with the detachable inner and outer rings permitting interference fits. This also offers quick assembling and interchangeability. 

The above details show that a needle thrust bearingis best suitable for various applications.
