Everything Needs To Know About The Needle Roller Bearings

Choosing the right bearing for a specific purpose is sometimes tricky and challenging as plenty of bearings available in the market. Usually, bearings are available in three different types such as roller bearings, needle bearings, and ball bearings. Among them, Needle Roller Bearing is the lightest and smallest of the roller bearing family. This renders them a particular advantage for some application especially those requiring reduced space and weight. It accesses small and cylindrical rollers, often called as the needle rollers, which minimize friction between moving components. The needle rollers are actually the load carrying components of this bearing. They are fixed between two races, a shaft, and housing, or a single race and shaft based on the design of bearing.

Benefits of the needle roller bearing

Below mentioned are the benefits of needle roller benefits when compared to other members of the bearing family.

• Ability to handle a larger and more rigid shaft in the given application
• Higher load capacity when compared to single row ball or roller bearings
• Lower costs particularly for the drawn-cup type than machined versions
• Amazing rolling characteristics within the small cross section

Different types of needle roller bearings

Below mentioned are the some of the types of bearing with the needle-shaped rolling elements.

Drawn cup needle roller bearings

One of the common types of needle roller bearings is Drawn Cup Needle Roller Bearings. These bearings have a deep yet thin-walled outer ring that is drawn from sheet metal. Commonly, the bore is left open but can be capped on one side. Additionally, they are intended to fit perfectly over the shaft. Without the inner ring, the smoother operation is achieved. It is further divided into three types such as drawn cup with the cage and open ends, full complement bearings with open ends and drawn cup with the cage and one-closed ends.

Thrust needle roller bearings

Thrust Needle Roller Bearing is highly accessed in the applications where the load is sustained axially not radially. In fact, the rollers have axes that are perpendicular to the bearing’s bore shaft. This type of bearing is acceptable for shock loads and heavy axial. It will take up so much space when compared to thrust washer.

Besides, alignment needle roller, bearings, drawn cup roller clutches, needle roller bearings with machined rings, etc. are available under this category.
