The bearing is a mechanism used to reduce friction between two objects in rotary or linear movement. The first perceptions about the bearing were collected by Leonardo da Vinci in his studies concerning friction. However, the first to file a patent was Philip Vaughan di Carmarthen in 1794. On the other hand, a Parisian bicycle mechanic named Jules Suriray was the one who patented the first ball bearing for bicycles, thanks to which he won the first cycling competition in history held on August 3, 1869 on the occasion of the Paris-Rouen race. In this video we will see how bearings work, and what are the main types that we find. JAES, which has been involved in the industrial supply sector for over ten years, has become the reference partner for some of the most important companies in the metallurgical world. JAES offers its services to supply many types of bearings. Now, let's take a closer look at a classic ball bearing. If we disassemble and section it, we can analyse its different elements. The elements that draw our attention the most are the steel balls. These represent the rolling element. They are placed together in a cage made of anti-friction materials that can take very different shapes. On the other hand, this is the inner ring, which is normally in motion. While this is the outer ring. Both have their race, which can be more or less deep, and has the role of a sliding channel for the rolling elements. It is common for the bearing to also have a shield, which can be metallic to protect it from dust, or made of plastic material to prevent liquid leaks. These shields are placed in specific places between both rings, in order to seal and protect the balls and the cage from external agents. At the same time, sealing them will keep the oil or grease inside the bearing, thus guaranteeing lubrication for its entire life cycle. In order to function correctly, the bearing must allow a certain “internal clearance”, that is, the displacement of one ring relative to the other in a radial or axial direction. So that, once the operating temperature is reached, the thermal expansion of the bearing does not cause its deterioration, or in the worst case, seizure. There are different types of bearings that are mainly divided into: radial, oblique and axial. At the same time, rolling bearings can be ball or roller. The three categories of bearing that we have just mentioned are differentiated based on the direction of the load: Radial bearings are designed to withstand forces that are perpendicular to the direction of the axis. Oblique bearings support both perpendicular and axial loads. While axial bearings are designed to withstand the force in the same direction as the axis. The rolling elements of the bearings facilitate movement. These are balls, as we have already seen, although they can also be rollers positioned between the fixed part and the moving part. In general, the most commonly used are ball bearings. In most cases, radial ball bearings have a single ball ring, while in particular cases they could also have two rings in order to withstand higher radial loads. Within the category of radial ball bearings, we find orientable bearings with two ball rings. This type of bearing has an inner ring with two races placed side by side, while the outer ring has a single hemispherical race. This system tolerates the inclination of the axes of both rings during operation. On the other hand, there are also oblique ball bearings that can have one or two ball rings. These are characterized by having an oblique position with respect to the axis of rotation of the load line that passes through the contact points between the balls and the rings. Angled ball bearings are capable of withstanding higher radial loads and axial thrusts. Finally, it should be noted that all these variants can also have an axial configuration to primarily withstand an axial load. These are also called thrust bearings. The other major category of rolling bearings are thrust bearings.
