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. 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.
Run through Sliding 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

 

1) 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.
 

2) Side roller

The side roller is the second bearing body of a set of composite rollers, which mainly bears horizontal load, and also has 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.
 

3) Shaft head

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

4) Cover plate

The function of the cover plate is an important part of fixing the side rollers installed inside the shaft head, the main rollers outside the shaft head with nuts and thread glue at the end of the shaft head.
