But the production ofbearings is a very important business, since without bearings many objectscould not work. But what are bearings? And how do they work? Withoutgiving too specific explanations, and without starting speaking about scienceand technology using terms that most people might not understand, we can saythat bearings are mechanical devices that are used to reduce friction betweentwo objects which rotate or move in a linear way. There are various types ofbearings, depending on the type of application and on the way they are built.No wonder that the production of bearings has enormously developed anddifferentiated since the first bearings were patented in the 18thcentury. The first patent of a ball bearing dates back to 1794 and wasregistered by Philip Vaughan in Wales. Almost a century later, more preciselyin 1896, it was French Jules Sururay that registered a second patent, but atype of bearing similar to the ones we know nowadays was presented only in1883. These bearings were launched by Friedrich Fscher. Plastic bearings,bearings for showers and all the other kinds of bearings that are now anessential part of many objects can be considered as the modern descendants ofthose first models of bearings. The bearings that you can find on the market do notbelong to only one category. On the contrary, the production of bearings hasundergone a great differentiation and development, and nowadays there arevarious types of bearings, each one with specific peculiarities that make itmore suitable for specific uses and applications. When you are to choose a typeof bearing, you need to take many factors into consideration, and althoughthere are no fixed rules for the choice of the ideal bearing for each field,still you can follow some general suggestions. First of all, you need toconsider some variables of the types of bearings, like space at disposal,loads, speed, noiselessness, rigidness, any incorporated protective devices andso on. Secondly, when you deal with a bearing system, you need to keep in mindthat there are other essential features apart from bearings. Choosing the righttype of bearing, considering also the most suitable size, is important but notsufficient. You need to consider also the most suitable protective devices, thetype of lubricant, the methods of installation and disassembly and so on.Lubricant is notably important, as it prevent the bearing from getting damagedin a short time. Moreover, lubricant is important for other reasons: it reducesfriction making the movement of rollers easier; it protects the bearings fromexternal agents; it mitigates the heat caused by movement and friction. Thereare two main types of bearing lubrication: grease and oil. The first one ismore common, as it has more advantages than the latter: grease, indeed,dissipates less that oil and is better at protecting bearings from impurities andcorrosion. Taking all these and other variables intoconsideration you can choose the best bearings for any situation.
