Roller Bearing Structure

- Apr 13, 2018 -


The outer ring of the roller bearing adopts a full-loaded cylindrical roller bearing with a thick outer ring wall. 

The outer diameter surface of the roller has a cylindrical shape and an arc shape. It can be designed to match the raceway surface according to the use occasion. 

With this outer ring, the rollers can be rolled directly on the raceway and can withstand heavier loads and shock loads.

The combined roller bearing consists of a main roller, side rollers, a shaft head and a cover plate.

The bearing is a sealed structure filled with grease, providing long-term effective lubrication, no need more lubrication at user's. 

For the use of poor working conditions can be designed to supplement the grease channel, improve bearing life. Improper handling can also cause the roller bearings to heat up. Lubrication can reduce the wear in the movement of parts, ensure press accuracy, and reduce energy consumption. Lubrication is divided into thin oil lubrication and thick oil lubrication.

Combination of roller bearings


1) Main wheel

The main roller is the most important carrier among the composite rollers. It mainly bears vertical load and impact load. It has strong impact resistance, wear resistance and corrosion resistance. Because the main roller is a full-loaded roller bearing, it can also be used as a one-way bearing alone.

2) Side roller

The side roller is a second carrier among the composite rollers. It mainly bears the horizontal load. It also has strong impact resistance, wear resistance and corrosion resistance. The side roller is designed with no inner ring full needle roller, and a mandrel is used to replace the inner ring and the shaft head.

3) Axle head

The shaft head is used as the connecting part of the compound roller and the machine equipment. Usually, the head of the shaft head is designed as a chamfer, which is convenient for installation. The shaft head can be directly welded on the equipment, and the shaft head can also be welded on the connection with a round hole. The board is then assembled with the equipment.

4) Cover plate

The role of the cover plate is to install the important part of the side roller installed inside the shaft head, the main roller outside the shaft head with a nut and thread glue at the end of the shaft head.
