What is the main purpose of the roller bearing?

The outer ring of the roller bearing adopts a full-filled cylindrical roller bearing with a thick outer ring wall. The outer diameter surface of the roller has a cylindrical shape and an arc shape, and can be matched with the raceway surface according to the design of the use occasion. It is widely used in various industries, such as machine tools and metallurgy.

The outer ring of the roller bearing adopts a full-filled cylindrical roller bearing with a thick outer ring wall. The outer diameter surface of the roller has a cylindrical shape and an arc shape, and can be matched with the raceway surface according to the design of the use occasion. With this outer ring, the roller can roll directly on the raceway and can withstand heavy loads and shock loads. The bearing is a sealed structure, filled with grease, providing long-term effective lubrication, and users can be free of lubrication. Improve the bearing life by using a channel that can be designed with replenishing grease in harsh conditions. Improper means can also cause the roller bearing to heat up. Run


Slip can reduce wear and tear in parts movement, ensure press accuracy and reduce energy consumption. Lubrication is divided into thin oil lubrication, concentrated oil lubrication, etc.

Composition of combined roller bearings

1) Main wheel

The main roller is the most important carrier of a set of composite rollers. It is mainly subjected to 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 as a one-way bearing alone.

2) Side roller

The side roller is the second carrier of a set of composite rollers, which is mainly subjected to horizontal load, and also has strong impact resistance, wear resistance and corrosion resistance. The side roller is designed with no inner ring full needle roller, and a core shaft replaces the inner ring and the shaft head to carry the bearing.

3) Shaft head

The shaft head is used as the part of the composite roller and the machine equipment. Usually the head of the shaft head is chamfered for easy installation. The shaft head can be directly welded to the equipment, or the shaft head can be welded to the connection with round holes. The board and equipment are assembled on the board.

4) Cover

The function of the cover plate is to form an important part of the side roller mounted inside the shaft head, the main roller outside the shaft head with a nut and a thread glue fixed at the tail end of the shaft head.
