Talking about the characteristics and functions of the lower bolt roller bearing The bolt roller bearing is mainly composed of four parts: the main roller, the side roller, the shaft head and the cover plate. Next, let's take a look at the features and functions of each part. The first is the main scroll wheel. The main roller is the main bearing body in the bolted roller bearing. It can withstand the impact load and load in the vertical direction, and has strong corrosion resistance, wear resistance and impact resistance. Because the main roller is a full complement roller bearing, it can also be used as a one-way bearing alone, followed by the side roller. The outer ring of the bolted roller bearing is a full complement cylindrical roller bearing with thick outer ring wall. With this outer ring, the rollers can roll directly on the raceway. And can withstand heavier loads and shock loads. The side roller is the second bearing body in the bolt roller bearing. It can accept the load in the horizontal direction. Like the main roller, the side roller also has strong corrosion resistance, wear resistance and impact resistance. The design method it adopts is that there is no inner ring full of needle rollers, and a mandrel is used to replace the shaft head and the inner ring to connect the bearing. Next is the shaft head, which is the part of the machine equipment that engages the bolted roller bearing. In general, the head of the shaft head is designed in a chamfered shape, which is easy to install, and then the cover plate, which is the part that fixes the side rollers and the main rollers together. Improper method of the bolt roller bearing can also cause the bolt roller bearing to heat up. Bolted roller bearings generally have a large bearing capacity and can be applied to various support structures with limited installation sizes. Before the bearing is installed, an appropriate amount of grease is generally injected. Therefore, under normal circumstances, after the installation of the product is completed, the user does not need to add lubricating oil separately. The cover of the product is closed, which has achieved the function of sealing and can withstand sliding in a small axial environment. This product has a relatively long service life and is highly regarded by many users. The support bolt roller bearing, which is the same as the bearing, can also bear a higher load and can also bear the load pressure caused by the external impact. However, the structure of this product is more compact and diverse, and the rotation accuracy during operation is relatively high. There are many varieties on the market, and it is relatively easy and simple to install. In the production process of modern enterprises, it is widely used in various industries, such as machine tools, metallurgy and other industries.
