Needle Thrust Bearing | sulochanapatil.files.wordpress.com
When it comes to solving issues with regard to accuracy and performance of machines at high speeds, various types of bearings with improvisations in the size, design and shape are used. The
advancements in engineering technology has helped in the development of suitable bearings, which can be used particularly for applications demanding high performance under harsh conditions.
Some Reasons to Use Needle Thrust Bearing in Applications
Where heavy axial loads are to be managed by using a minimum space, a needle thrust bearing is used. It is recognized for offering compact solutions to space scarcity. A needle thrust bearing is available in
different design variants, with standard sizes, series and dimensions to help easy and quick interchangeability. Aneedle bearing catalogue has all the details to help you find an appropriate
bearing design for applications, which have a limited envelope space and where the faces of the adjoining components can be used as ring washers.
Nevertheless, it needs much care to select a bearing for applications that ask for high performance at high speeds and under changing heavy load conditions. Being small enough, a needle thrust
bearing makes the machine much compact by using minimal axial space. In a way, it is equal to a conventional thrust washer but it provides a high degree of stiffness. Some applications like
high-pressure pumps, machine tools and automobile components like pivots, compressors, etc., largely use this bearing.
Get to Know Some Innate Features of a Needle Thrust Bearing
The bearing design is available in two popular types:a single-row needle thrust bearing and double-row needle thrust bearing, and they both have numerous needle rollers and a cage. The assembling
unit comes with a shaft and housing, which is the raceway surface. The other inherent features of the bearing are:
Occupies minimal space: A needle thrust bearing permits downsizing by providing minimum space solutions. With a bearing variant like a drawn-cup needle thrust bearing, you find a
solution having low-cross section for space scarcity.
High rigidity: It offers high rigidity due to a large number of rolling elements of small diameters.
Easy maintenance: With separable inner and outer rings, a needle thrust bearing allows interference fits, which facilitates easy maintenance and assembling.
Manages heavy loads: Having innumerable needle rollers, a needle thrust bearing handles heavy loads easily.
Accommodates axial displacement: The bearing does not require flanges to handle axial displacement under heavy load conditions. It is designed to have with or without inner and
outer washers.
Enables self-alignment: Where there is static misalignment, a bearing can self-align up to three percent.
The above information, makes a needle thrust bearing suitable for various applications.
