Above all bearings.
Bearing manufacturers produce bearing to allow relative motion that is linear or rotational between two parts. They act more like an anti-friction device and are very important part in mechanical technologies and such. Bearings uses either balls or rollers to reduce the friction.
Have you noticed that things are better off rolling rather than sliding? This is because sliding basically causes friction which slows down the speed of the object. But, if the parts roll over one another, friction is greatly reduced. And this happens to be the concept behind bearings.
There are other machinery used to reduce friction, and some of these are: clutches, torque limiters, rotary dampers and rollers. Bearings are actually differentiated according to their motion, direction of load and most especially, the principle of their operation.
You can find bearings in a variety of type and uses. Used in inline skating, the ball bearings are the most popular one among all the bearing types. These bearings are useful in the case when the load is relatively small and can handle both thrust and radial loads.
But when it comes to the food industry, plastic bearings are the ones that are commonly used. This is because plastic bearings are good in both conditions such as wet and corrosive. They are also non-magnetic which is sometimes a necessity in food processing machines. Plastic bearings find its uses in vending machines, refrigerators and in office furniture as well. Steel bearings are more applicable for those that needs high-load precision bearings. There are other types of precision bearings products that you can find nowadays.
There exist miniature bearings that are corrosion resistant, light weight and cost effective. These types of bearings are usually used in office equipments and such. Ball bearings are the most cost effective among all bearing types as producing the balls used in these bearings is least expensive. Again, bearings are mainly produced to effectively reduce friction and to support radial and axle loads.
With the advancement of technology, harder and stronger bearings are now available for use. And example of these bearings are those used as rollers for elevators.
One of the precision bearings manufacturers under Emerson Power Transmission, and they are also the ones who produced the first ever CAMROL cam follower bearings. They also produce the industry’s broadest line of precision bearings in both standard and special “Engineered-To-The-Application” designs.
