Composition and application of roller bearings

The outer ring of the roller bearing adopts a full-complement cylindrical roller bearing with a thicker outer ring wall. The diameter of the roller is cylindrical and arc. It can be matched with the raceway surface according to the design plan of the application site. Using this type of outer ring, the roller can instantly flip on the raceway and can withstand heavier loads and impact loads.

    The rolling bearing has a sealed structure and is filled with lubricating grease to show long-term effective lubrication, and customers can avoid lubrication. Designed solutions for extreme application working conditions can fill the safe passage of lubricating grease and improve the service life of rolling bearings. It is widely used in various industries, such as CNC lathes, metallurgical industry and other manufacturing industries.

    The composition of roller bearings

    1) Main roller The main roller is the most critical medium of a set of composite rollers. It is critical to bear vertical loads and impact loads, and has strong impact resistance, wear resistance and corrosion resistance.

    Because the main roller is a full complement roller bearing, it can also be used independently as a one-way bearing.

    2) Side rollers Side rollers are the second bearing medium among a set of composite rollers, which are critical to bear the horizontal load, and also have strong impact resistance, wear resistance and corrosion resistance. The side rollers are designed with no inner holes and full needles, and a mandrel replaces the inner hole and the shaft head to bear the load.

    3) Shaft head Shaft head is used as a part of the connection between composite rollers and mechanical equipment. Generally, the top of the shaft head is designed with rounded corners for easy installation. The shaft head can be immediately welded to the machine and equipment, or it can be The shaft head is welded by electric welding to the connecting plate with round holes, and then the connecting plate and the machine equipment are assembled.

    4) Rear cover The function of the rear cover is to fix the side rollers installed inside the shaft head and the main roller outside the shaft head with nuts and threaded glue at the end of the shaft head. The key components are not to move together.

The outer ring of the roller bearing adopts a full complement cylindrical roller bearing with a thicker 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 thicker 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.

Using this outer ring, the roller can roll directly on the raceway and can withstand heavier loads and shock loads.

The bearing has a sealed structure and is filled with grease to provide long-term effective lubrication. Users can avoid lubrication.

For harsh operating conditions, a channel for replenishing grease can be designed to increase the service life of the bearing.

Improper way can also cause the roller bearing to heat up. Lubrication can reduce the wear in the movement of parts, ensure the accuracy of the press, and reduce energy consumption. Lubrication is divided into thin oil lubrication and thick oil lubrication.

Composition of combined roller bearings

Main roller The main roller is the most important bearing body in a set of composite rollers. It mainly bears 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.

Side rollers The side rollers are the second load-bearing body of 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 no inner ring and full needles, and a mandrel replaces the inner ring and the shaft head to carry the load.

Axle head Axle head is used as the connection part of the composite roller and the machine equipment. Usually the head of the shaft head is designed with chamfering, which is convenient for installation. The shaft head can be directly welded to the equipment, or the shaft head can be welded with a round hole. Then assemble the connection board and the device on the connecting board.

The function of the cover plate is to fix the side rollers installed inside the shaft head and the main rollers outside the shaft head with nuts and thread glue on the shaft head and tail.
