Bearings are small device yet; the magnitude of its importance cannot be overlooked. Can you imagine a life without a car, airplane or trains in the present world? The bearings are the ‘hidden heroes’ of not just these inventions but, a range of others such as vacuum cleaner, transmissions, washing machines, computers, refrigerators, air conditioners etc. Bearings are not any recent discovery. In fact its importance was realized way back in the ancient period. Its production increased tremendously in the Industrial Revolution of the 18th century. Today, we have bearings of many types some of which includes cylindrical roller bearings, needle roller bearings, pins, ball bearings, tapered bearings and the like.
What are Needle Rollers?
Bearings which used small cylindrical rollers are classified as needle roller bearings. The rollers are thin and the end of the rollers usually tapers to points. The outer diameter of the needle bearing is to some extent larger than the hole. It is one of the most preferred choices of bearings for a number of automotive, industrial and textile sectors.
Uses of Needle ...
... Rollers:
Needle rollers have a number of applications of which some of them are listed below:
Transmission
Engines
Valve trains
Axle supports
Textile industry
Alternators
Steering gears
Fax Machines
Paper-moving equipment
Appliances
Universal joints
Outboard engines
Braking systems
Functions of Needle Rollers Bearings:
One of the most important functions of needle rollers is that they have a high capacity to carry heavy loads.
Needle rollers have greater rigidity
They have the power to operate in adverse conditions
Apt for handling applications where there is limited radial space
They aid in reducing friction of a rotating surface.
Since the needles are very small in diameter, the bearing can fit into tight places.
Types of Needle Roller Bearings:
Needle roller bearing comprises of:
Drawn cup: Comprises of an outer ring with pressed steel.
Precision race: Comprises of machined outer ring of a solid type
Caged roller: Some come with pressed steel cage while there are others that come without cage.
Thrust roller: Comprises of a single row roller and assemblies of cage. They also include thrust needle bearings
Single and double row bearings: Comes with or without the inner rings
Other types of needle roller include the yoke and stud type.
