Working principle of the rolling bearing and sliding bearing

Surface pressure, because of the large contact area is more smaller, and you can use soft shaft axis or other materials, such as aluminum alloy, carbon fiber, etc. , so the sliding bearing is one of the many advantages of further reduce weight. Because there is no hard friction parts for mechanical rolling, also does not have the rolling body collide with each other, so the sliding operation noise and vibration will be less. Use linear sliding bearing, the guide rail can be joining together, which can easily form a long trip, the reason is that the movement of the sliding element easier than scrolling through the guide rail joint. All ball bearings and related materials of a major disadvantage is that allows the velocity and acceleration constraints, the maximum value is limited, especially in low load. Engineering plastic sliding bearing, by contrast, has high sliding speed and acceleration, thus greatly improve the cycle time in many applications. But the most important trump card is its service life, bearing made of high-performance engineering plastics are usually want to be more durable than traditional ball bearing. In addition, its service life can be through a variety of programs to calculate. In the past few years, both accuracy and friction values have made great progress. Before using traditional ball bearing has now started to use in a broad range of areas, engineering plastic sliding bearing.
