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

structure

The outer ring of the roller bearing adopts the full loaded cylindrical roller bearing with thick outer ring wall. The outer diameter surface of the roller has cylindrical and arc shape, which can be matched with the raceway surface according to the design of the use situation. With this kind of outer ring, the roller can roll directly on the raceway, and can bear heavy load and impact load. The bearing is a sealed structure, filled with grease, providing long-term effective lubrication, and the user can avoid lubrication. For the poor service conditions, the channel for supplementing lubricating grease can be designed to improve the service life of the bearing. Improper way can also cause roller bearing heating. Lubrication can reduce the wear in the movement of parts, ensure the accuracy of press and reduce energy consumption. Lubrication is divided into thin oil lubrication, thick oil lubrication, etc.

Composition of combined roller bearing

1) main roller

The main roller is the most important bearing body of a set of composite roller, which mainly bears the vertical load and impact load, and has strong impact resistance, wear resistance and corrosion resistance. As the main roller is full loaded roller bearing, it can also be used as one-way bearing alone.

2) side roller

The side roller is the second bearing body in a set of composite roller, which mainly bears horizontal load, and also has strong impact resistance, wear resistance and corrosion resistance. The side roller is designed to be full needle roller without inner ring, and it is supported by a mandrel instead of inner ring and shaft head.

3) axle head

The shaft head is the part connecting the composite roller and the machine equipment. Generally, the shaft head is designed to be chamfered for easy installation. The shaft head can be directly welded on the equipment, or the shaft head can be welded on the connecting plate with a round hole, and then the connecting plate and the equipment are assembled.

4) cover plate

The function of the cover plate is to fix the side roller installed inside the shaft head and the main roller outside the shaft head together with nuts and screw glue at the end of the shaft head.
