The bearing capacity of the roller bearing is generally large, and it can be applied to various supporting structures with limited installation size. 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. As the support roller bearing of the same kind of bearing, it can also bear a higher load and can also bear the load pressure caused by 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. The outer ring of the roller bearing adopts a full complement cylindrical roller bearing with a thick outer ring wall. The outer diameter surface of the roller has a cylindrical shape and an arc shape, which can be designed to match the raceway surface according to the application. It is widely used in various industries, such as machine tools, metallurgy and other industries. Structure The outer ring of the roller bearing adopts a full complement cylindrical roller bearing with a thick outer ring wall. The outer diameter of the roller has cylindrical and arc shapes, which can be designed to match the raceway surface according to the application. With this outer ring, the rollers can roll directly on the raceway and can withstand heavier loads and shock loads. The bearing is a sealed structure, filled with grease to provide long-term effective lubrication, and users can avoid lubrication. For harsh operating conditions, a channel for supplementing grease can be designed to improve bearing service life. Improper method can also cause the roller bearing to heat up. Lubrication can reduce the wear of parts in motion, ensure the accuracy of the press, and reduce energy consumption. Lubrication is divided into thin oil lubrication, thick oil lubrication, etc. The composition of the combined roller bearing 1 Main roller The main roller is the main bearing body in a set of composite rollers. It mainly bears the vertical load and impact load, and has strong impact resistance, wear resistance and corrosion resistance. Since the main roller is a full complement roller bearing, it can also be used alone as a one-way bearing. 2 Side rollers Side rollers are the second bearing body in a set of composite rollers, which mainly bear horizontal loads, and also have strong impact resistance, wear resistance and corrosion resistance. The side rollers are designed with full needle rollers without inner ring, and a mandrel replaces the inner ring and the shaft head to connect and carry. 3. Shaft head The shaft head is used as the connection part between the composite roller and the machine equipment. Usually the shaft head head is designed to be chamfered, which is convenient for installation. The shaft head can be directly welded on the equipment, or the shaft head can be welded on Then assemble the connecting plate and the device on the connecting plate of the hole. 4 Cover plate The function of the cover plate is to fix the side rollers installed inside the shaft head and the main roller outside the shaft head with nuts and thread glue at the tail of the shaft head.
