Stud Cam Follower Roller Bearing constitute

The combination stud cam follower bearing consists of the main roller, the side roller, the shaft head and the cover plate.The cam follower bearing is a sealed structure, which is filled with grease to provide long-term effective lubrication, thus avoiding lubrication.For the poor service conditions can be designed to supplement the grease channel, improve the service life of the bearing.Improper way can also cause roller bearing heat.Through lubrication can reduce the motion of parts wear, ensure the accuracy of the press, reduce energy consumption.Lubrication divided into thin oil lubrication, thick oil lubrication, etc.

Stud Cam Follower Roller Bearing lubrication

The outer ring of Cam follower bearing adopts the full-loaded cylindrical roller bearing with thick outer ring wall. The outer diameter surface of the roller is cylindrical and curved, which can be designed to match with the raceway surface according to the use situation.With this outer ring, the roller can roll directly on the raceway and can withstand heavy loads and shock loads.The combination Cam follower bearing consists of the main roller, the side roller, the shaft head and the cover plate.The Cam follower bearing is a sealed structure, which is filled with grease to provide long-term effective lubrication, thus avoiding lubrication.For the poor service conditions can be designed to supplement the grease channel, improve the service life of the bearing.Improper way can also cause roller bearing heat.Through lubrication can reduce the motion of parts wear, ensure the accuracy of the press, reduce energy consumption.Lubrication divided into thin oil lubrication, thick oil lubrication, etc.

The composition of the composite Cam follower bearing

1) the main roller is the main carrier of a set of compound roller, which mainly bears the vertical load and impact load, and has a strong impact resistance, wear resistance and corrosion resistance.As the main roller bearing is full loaded, it can also be used as a one-way bearing alone.

2) the side roller is the second carrier in a set of compound roller, which mainly bears the horizontal load and also has strong impact resistance, wear resistance and corrosion resistance.The side roller is designed with full needle without inner ring, and a mandrel is used to replace the load bearing of inner ring and shaft head.

3) the shaft head is the part connected with the machine and equipment as the compound roller. Usually, the shaft head is designed with chamfering Angle, which is convenient for installation. The shaft head can be directly welded to the equipment, or the shaft head can be welded to the connection plate with circular holes, and then the connection plate and equipment can be assembled.

4) the cover plate is used to fix the side roller inside the shaft head and the main roller outside the shaft head together with nuts and thread glue at the end of the shaft head.
