As the name implies, a needle roller thrust bearing is a type of bearing that uses thin cylindrical rollers (called needles) as the main bearing element. These rollers typically have an outside diameter less than half that of the shaft and are therefore able to support large loads or shocks.
The main advantage of needle roller bearings is their ability to withstand high loads or shocks. This is due to the small difference in diameter between the needles in the same cage. To reduce the contact pressure on the raceways, the ends of the needles are slightly depressed. This allows them to better withstand high loads without damaging the raceway.
The main disadvantage of needle roller thrust bearings is that they are not well suited for high-speed applications. This is because the small diameter of the needles limits the amount of lubricant that can be used, which can lead to increased friction and heat at high speeds.
When selecting a needle roller thrust bearing, it is important to consider the following factors:
There are many models of needle roller thrust bearings. So, when you are looking for a product, you have to define the inner diameter, the outer diameter, the thickness, the brand, and other technical characteristics. You can search for your needle roller thrust bearing on the 123Bearing website by entering your reference in the search bar or by filtering your search according to your specificities. Then, you just have to add the product to your basket.
