Bearing how does it work

Roller Bearings, like the one illustrated at right, are used in applications like conveyer belt rollers, where they must hold heavy radial loads. In these bearings, the roller is a cylinder, so the contact between the inner and outer race is not a point but a line.

This spreads the load out over a larger area, allowing the bearing to handle much greater loads than a ball bearing. However, this type of bearing is not designed to handle much thrust loading.

A variation of this type of bearing, called a needle roller bearing , uses cylinders with a very small diameter. This allows the bearing to fit into tight places. Ball Thrust Bearings, like the one shown on the left, are mostly used for low-speed applications and cannot handle much radial load. Barstools and Lazy Susan turntables use this type of bearing. Roller Thrust Bearings, like the one illustrated to the right, can support large thrust loads.

They are often found in gearsets like car transmissions between gears, and between the housing and the rotating shafts. We need now to introduce one more very important component of bearings. Have you ever had a plate covered with oil slip out of your hand when you held it? You probably all understand that when there is oil between two surfaces the amount of friction is decreased. Bearings aim for stable and smooth rotation, and to do that the friction with rolling motion needs to be reduced and the abrasion of the various components needs to be prevented.

This is the job of the "lubricant". Semi-solid i. The lubricant also serves to remove the heat that is generated inside the bearing as it rotates, serving to increase the service life of the bearing. For this reason lubricant is an important component in allowing bearings to rotate stably and smoothly.

Bearing rings races , rolling elements and cages all play a role in allowing bearings to function, and it is by combining these functions that bearings rotate smoothly.

On top of these components, lubricant also helps to reduce friction in the rolling motion, preventing abrasion. In this way, each component of the bearing serves an important function, allowing the bearing to continually rotate stably and smoothly.

What types of bearings are there, and what kind of special features do they have? Be sure to read Part 4 to find out! Part 1: What Are Bearings? The amazing history of bearings Part 3: What's the Structure of the Bearing? Bearing Trivia for Beginners: "Fits". Site search. Product information List of product types. Deep-Groove Bearings : designed to carry both radial and light axial loads. Linear Bearings : designed to allow movement in one direction along a linear axis. Self-aligning Ball Bearings : bearings with two sets of balls that are self-aligning and to carry both radial and light axial loads.

High-Speed Angular Contact Bearings : another type of precision ball bearing is a high-speed angular contact bearing. As the name implies, high-speed bearings are designed to handle high RPMs with precision and accuracy. Careers Review our current job openings and apply.

Bearings support the rotating shafts of the wheels, gears, turbines, rotors, etc. In this way, all sorts of machines require a great many shafts for rotation, which means bearings are almost always used, to the point where they have become known as "the bread and butter of the machine industry". At first glance, bearings may seem like simple mechanical parts, but we could not survive without bearings.

Friction is bound to occur between the rotating shaft and the part that supports the rotation. Bearings are used between these two components. The bearings serve to reduce friction and allow for smoother rotation. This cuts down on the amount of energy consumption. This is the single most important function of bearings. A large amount of force is needed between the rotating shaft and the part that supports the rotation. Bearings perform the function of preventing damage from being done by this force to the part that supports the rotation, and also of maintaining the correct position of the rotating shaft.

This function of bearings is what allows us to use our machines over and over again for an extended period of time. Let's ask ourselves just how much our daily lives are dependent on bearings.

You don't normally see them so it's a bit difficult to imagine, right? Let's talk a bit about cars, since those are something we all know. When you were a child, you probably played with an electric toy race car set at least once, right?

You might remember that the bearings where the wheels were attached. Please click the link below for more detailed information on bearings for use in cars:.
