What Is a Bearing?


A bearing refers to a mechanical device that sustains the moving section of an engine and to confine or guide its motion, while putting off motion in the course of applied weight.  Its main objective is to lessen friction with a bare minimum energy loss and simultaneously to control the wear and tear.  Bearings are produced to support the thrust loads, radial loads, or combined thrust-radial loads.

This piece of equipment can be located between the frame shafts of the machine or between the frame of the machine or the contact members. It can also be located between the frame and contact members or between the linkage members and the contact members.  The two most popular forms of this tool are the linear bearings and rotary bearings.

Linear bearing is used to allow movement in a straight direction.  Say for example, your cabinet drawer is making use of this tool to assists the pulling of the drawer back and forth.  Meanwhile, rotary bearing helps in moving around an object in a central spot. Like for example, wheel on the shaft rotates using this tool.  Rotary bearings may include oscillation and one-direction rotation.

With oscillation, this tool goes only through to a section of a rotation.   Other forms of bearings use a different principle when it comes to its design.  The tool that uses a rolling element is called the ball bearings and roller bearings.  This rolling element carry load through placing a spherical element between two parts.  This makes the spherical elements to tumble or to roll with a slight sliding.

Fluid bearing is another common type of tool used.  This tool functions by carrying the load either in a gas or liquid form.  This tool is used when a procedure requires high precision, high loads or high speed, because actual ball bearings will quickly wear out if used in this application.

Magnetic bearing is used when a weight is carried by means of magnetic field.  It is often used in electrical meter to determine power consumption.  It is also used to support the train resulting in a lesser noise and smoother ride.  This tool offers an extremely low friction and can perform work even without using lubrication.    It can also function in vacuum but it is very expensive.

Flexure bearing is used if the weight element needs to twist.  Usually, this tool is considered as one section that combines two other sections.  An example of this tool is a door hinge.  This tool is inexpensive and simple.  It is also lightweight and creates little amount of resistance.  The scope of movement is also limited and it cannot support higher load.

Bearing is designed in a way that it can offer lesser friction and to support various types of loads.  It also helps in providing precise performance with varying speeds and loads.

What are the different kinds of Bearings?



The various kinds of bearings are used for wide array of purposes. The type includes the tapered roller thrust, roller thrust, and ball thrust, roller and ball bearings.

Ball Bearings

Ball bearings are one of the most popular and commonly used of all types. It can be found from almost everything such as the hard drives to inline skates. This type can also handle both the thrust loads and radial loads. It can be found in those applications wherein there is a relatively small load.

It works by transmitting the load from the balls outer race and coming from the ball to its inner race. It is also shaped like a sphere so it can only contact the outer and inner race in a very little point that helps in a smooth spinning. It is also important to note that there is not much area of contact that holds the load, thus if the ball bearing becomes overloaded the tendency of the ball is to squish or deform which will ruin the entire bearings.

Roller Bearings

The roller bearings are used in various applications like the conveyer belt rollers, where it is responsible for holding heavy-duty radial loads. In this kind of bearing, the roller is cylinder shaped, so the outer and inner race contact is not within a point but through a line. This will spread the load in an outer direction over a large area, thus it allows the bearing to hold heavier loads compared with the ball bearing.

However, this type is not created to hold much compared with the thrust loading. Another variation of this kind is the needle bearing which uses a cylinder with an extremely small diameter allowing it to be fitted into small and tight places.

Ball Thrust Bearing

The Ball Thrust is commonly used for applications requiring low-speed performance and it cannot hold more radial load. The turntable and barstools uses this type of accessories.

Roller Thrust Bearing

The roller thrust is used to support larger thrust loads. It can be found in the gear sets such as the car transmissions in between the gears, rotating shafts and the housing. Helical gears which are commonly used in transmissions are characterized by angled teeth which causes thrust load that needs to be supported by this kind of bearing.

Tapered Roller Bearings


The tapered roller is used to support larger thrust and radial loads. It is also commonly used for car hubs where it is mounted in a paired order. The paired bearings are faced in opposite direction to allow them to handle the thrust in both of its directions.
