Difference between high-speed and low-speed bearings Many people may misunderstand it, it’s not that the rotation speed of the bearing itself, but its linear speed. Many low speed bearings can reach tens of thousands of revolutions per minute, on the other hand, for some high-speed bearings, the data of rotations per minute maybe only just a few hundred. There are also some other differences between the two. Generally, low-speed bearings have a rougher appearance, and the joints between parts are looser. To ensure its accuracy, the precision of high-speed bearing is generally very smooth on the surface, and the distance between the inner ring and outer ring is minimal, the accuracy is much higher. Many high-speed bearings are also super-precision bearings. It normally use special high speed grease. In terms of material, there is also a slightly difference between high-speed bearing and low-speed bearing. High speed bearings are generally made of very high hardness steel, which can withstand the pressure caused by excessively high speeds. If it’s low, some common materials are used, the requirements for hardness and durability of the material are relatively reduced. What to do if the high-speed bearing is overloaded and hot? 1) In the case…
