Needle Roller Bearings
A needle roller bearings consists of cylindrical rollers. These rollers have small diameters in comparison to their length. This makes needle roller bearings a very special and unique type of bearing. It has a high load carrying capacity. Moreover, these rolling elements can also withstand vibrations with more rigidness than other bearing options. Needle roller bearings come in a wide variety of designs, shapes, metric and inch sizes, which makes them suitable for an even larger number of operations and applications. The main applications of needle roller bearings include gearboxes, vehicle transmission, two and four-stroke engines, air compressors, etc.

What are needle roller bearings?
Needle roller bearings are the smallest and lightest type of roller bearing. This gives them a slight edge over other bearing types. These bearings have an advantage in applications that require reduced space and weight. The load capacity of this bearing is higher than single row and roller bearings. This bearing can also handle larger and stiff operations. They also have the ability to roll smoothly in a small cross section. The drawn cup needle roller bearings are cheaper as compared to refined versions.
Needle roller bearings are considered the most economical because it is a full complement of loose needles which are assembled directly into the shaft accommodation. Normally hardened washers are used for axial location.
What are needle bearings used for?
Needle roller bearings are used in many applications such as vehicle propeller joints, gearboxes, power transmission systems, rocker arm pivots, four-stroke engines, etc. This is specially used in applications where hardened shafts are featured as the outer raceway.
What is the difference between a roller bearing and a needle bearing?
The main difference between the two bearings lies in their diameter and length sizes. Thus, if the diameters and lengths of the rollers in a roller bearing are between point one and point four, that roller bearing is considered a needle bearing. Needle roller bearings also have a large exterior, when it comes into contact with the exterior surface as compared to ball bearings.
Another difference between roller bearings and needle bearing is that needle bearings come in a single row, double row, and solid or split cage assemblies.
Types of needle roller bearings and their applications
Needle roller and cage assemblies
These bearings provide a very efficient operating condition. These are separate and ready-to-mount, with high load capacity and extreme stiffness. This allows for a compact bearing arrangement, where the shafts serve as raceways.
Drawn cup needle roller bearings
This type has a walled outer ring. These bearings are used where the shaft cannot be used as a rolling element for the needle and rollers cage assembly. These bearings need to be mounted with a tight shaft. This makes it more economical and simple, as no other ring is required to locate axial loads.
Needle roller bearings with machined rings
These are compact with a high load carrying capacity and rigidness. This is a carbon chromium bearing, which is produced with or without inner and outer rings.
Alignment needle roller bearing
This needle has a self-aligning ability. These needle roller bearings comprise an outer ring with a convex-shaped outer surface and two seating rings with a concave-shaped inner area.
Combined needle roller bearings
This is a combination of a radial needle roller bearing and thrust bearing. This enables it to accommodate combined radial and axial loads. This also makes it very compact and supports high load carrying capacity.
Universal joint bearings
This is made with refined cup needle rolling elements, with a closed-end. These bearings are used in many applications, such as vehicle propeller shafts.
Needle roller bearing components
These are supplied as separate parts. The inner ring can be combined with a needle bearing and drawn cup needle bearings.
