In most of the bearings with rolling element, you will find either it is ball bearing type or roller bearing type. The category involves tapered, spherical, cylindrical, needle type bearings and many more. We are going to discuss about needle thrust type of bearing. If you know, a Thrust bearing is a special type of rotary bearing which predominantly supports axial type loads. Alike properties of any other bearing type, these needle thrust bearing also helps to reduce the friction of rotating surface and rotates around its own axle.

As the name indicates bearings that has tapered ring raceways and tapered rollers on both inner and outer side of ring raceways are known as Tapered roller bearing. The design is perfectly apt to accommodate radial and axial load. In order to provide perfect rolling action, the projection lines of raceways are found at common point along bearing axis. This provides a perfect rolling action and thus low level of frictional moment happens during operation of machine. These are common features of Tapered roller bearing
- Results in Low friction due to presence of lubrication
- Long serving duration due to crowned raceway
- Separable & interchangeable due to placement of inner ring alongside cage assembly and roller which gives flexibility to mount separately from outer ring.
Needle bearing catalogue
Almost all small or large manufacturer have detailed catalogue of their product range. Catalogue mentions entire list of items, typically in alphabetical order and also in specification wise systematically listed. It contains Technical information of the bearings with the drawing for the reference of the users for an easy understanding. If you have a look at catalogue or brochure of needle thrust bearing you will find the following information in order:
- Catalogue Edition number
- Main features
- Bearing Life detail with related information
- Formula for Basic Load Rating and calculation of loads
- How to fix in case of misalignment
- Machines wherein bearings are used and its projected life span
- Bearing Seals
- Bearing handling
- Bearing mounting
Usually the calculation tables at the end provide all engineering calculation for the user to go through the same and choose the ideal type of bearing. It gives complete detail about placing a bearing or how will it accommodate in case of radial / axial load is applied or else if both type of loads are present.
You will find many national and international suppliers on any bearing type such as needle thrust bearing product range. Few of them even offer flexibility to the consumer wherein the product can be slightly customised. One can either procure directly from the manufacturer or wholesaler based on budget, requirement, timeline and terms & condition. To ensure you get the right product always buy ISO certified product.
