(Summary description)The slewing bearing is a large bearing that can withstand the combined load and can withstand large axial, radial loads and overturning moments. The slewing bearing is also called a slewing bearing, and some people also call it a rotary support and a rotary support. There are differences in the working effect and size between the slewing bearing and the ordinary bearing. So, what is the difference between the slewing bearing and the ordinary bearing? The slewing bearing is identical to the bearing and has a rolling element and a raceway with a raceway. However, compared with ordinary rolling bearings, there are still big differences. Let's talk about the difference between the two. The biggest difference between slewing bearing and ordinary bearing: 1. The installation method is different. The slewing bearing is not mounted on the mandrel like the ordinary bearing and is installed in the bearing housing. Instead, it is fixed on the upper and lower supports by screws. 2, slewing bearings generally have to bear several aspects of the load, not only to withstand axial forces, radial forces, but also to withstand large overturning moments. Therefore, a set of slewing bearings often function as several sets of ordinary rolling bearings. 3. The running speed of the slewing ring is low, usually below 50 rpm. In many cases, the slewing ring does not operate continuously, but only rotates back and forth within the angle, which is equivalent to a so-called "swing bearing". 4, the size of the slewing bearing is larger than the ordinary bearing, its diameter is usually 0.4 ~ 10 meters, and even some diameters reach 40 meters. 5. Normally, the slewing bearing is provided with a ring gear for rotational driving and a sealing device for dustproofing. 6. In terms of manufacturing processes such as materials and heat treatment, there are great differences between slewing bearings and rolling bearings. Therefore, in the purchase of bearings, but also according to the size of the machine to choose, according to their own needs to choose the right product is the most important.
